Kerala Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination

What is excretion?
Excretion is the elimination common nitrogenous wastes. Ammonia, urea and uric acid are the major forms of nitrogenous wastes excreted by the animals.

Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination

Ammonotelic.ureotelic and urecotelic animals and their excretion:
1. The process of excreting ammonia is Ammonotelism. eg: Many bony fishes, aquatic amphibians and aquatic insects are ammonotelic.

2. Mammals, many terrestrial amphibians and marine fishes mainly excrete urea and are called ureotelic animals.

3. Reptiles, birds, land snails and insects excrete nitrogenous wastes as uric acid in the form of pellet or paste with a minimum loss of water and are called uricotelic animals.

Where is urea produced?
Ammonia produced by metabolism is converted into urea in the liver and released into the blood which is filtered and excreted out by the kidneys.

Excretion in lower organisms:

Protonephridia or flame cells are the excretory structures in Platyhelminthes (Flatworms, eg: Planaria), rotifers, some annelids and the cephalochordate – Amphioxus.
Nephridia are the tubular excretory structures of earthworms and other annelids
Malpighian tubules are the excretory structures of most of the insects including cockroaches.
Antennal glands or green glands perform the excretory function in crustaceans like prawns.

Human Excretory System
In humans, the excretory system consists of

  1. A pair of kidneys
  2. One pair of ureters
  3. A urinary bladder
  4. A urethra.

Each kidney of an adult human measures 10 – 12 cm in length, 5 – 7 cm in width, 2 – 3 cm in thickness with an average weight of 120 – 170 g.
Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination 1
1. Centre of the inner concave surface of the kidney is a notch called hilum through which ureter, blood vessels and nerves enter.

2. Innerto the hilum is a broad funnel shaped space called the renal pelvis with projections called calyces.

3. Inside the kidney, there are two zones, an outer cortex and an inner medulla.

4. The medulla is divided medullary pyramids projecting into the calyces.

5. The cortex extends in between the medullary pyramids as renal columns called Columns of Bertini.

6. Each kidney has nearly one million complex tubular structures called nephrons, which are the functional units. A diagrammatic representation of a nephron showing blood vessels, duct and tubule Each nephron has two parts -1 The glomerulus & 2 Renal tubule.
Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination 2
7. Glomerulus is a tuft of capillaries formed by the afferent arteriole – a fine branch of renal artery.

8. Blood from the glomerulus is carried away by an efferent arteriole.

9. The renal tubule begins with a double walled cup-like structure calle Bowman’s capsule, which encloses the glomerulus.

Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination

10. Glomerulus alongwith Bowman’s capsule, is called the malpighian body or renal corpuscle

11. The tubule continues further to form a highly coiled network proximal convoluted tubule (PCT).

12. A hairpin shaped Henle’s loop is the next part of the tubule which has a descending and an ascending limb.

13. The ascending limb continues as another highly coiled tubular region called distal convoluted tubule (DCT).

14. The DCTs open into a straight tube called collecting duct, many of which open into the renal pelvis through medullary pyramids in the calyces.

15. The Malpighian corpuscle, PCT and DCT of the nephron are situated in the cortical region of the kidney whereas the loop of Henle dips into the medulla.
Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination 3

Types of Nephrons:
1. In majority of nephrons, the loop of Henle is too short and extends only very little into the medulla. Such nephrons are called cortical nephrons.

2. In some of the nephrons, the loop of Henle is very long and runs deep into the medulla.These nephrons are called juxta medullary nephrons. A minute vessel of capillary network runs parallel to the Henle’s loop forming a ‘LT shaped vasa recta. Vasa recta is absent or highly reduced in cortical nephrons.

Urine Formation
1. It involves three main processes namely, glomerular filtration, reabsorption and secretion

2. The first step in urine formation is the filtration of blood, which is carried out by the glomerulus and is called glomerular filtration.

3. 1100 – 1200 ml of blood is filtered by the kidneys per minute. The glomerular capillary blood pressure causes filtration of blood through 3 layers,

(a) Endothelium of glomerular blood vessels
(b) Epithelium of Bowman’s capsule and
(c) Basement membrane between these two layers.

4. The epithelial cells of Bowman’s capsule called podocytes which possess minute spaces called filtration slits.

5. Blood is filtered through these membranes, that almost all the constituents of the plasma except the proteins pass onto the lumen of the Bowman’s capsule. It is the process of ultra filtration.

Glomerular filtration in a healthy individual is approximately 125 ml/minute, i.e., 180 litres per day

6. The kidneys have efficient mechanism for the regulation of glomerular filtration rate. It is carried out by juxta glomerular apparatus (JGA).JGA is found in the distal convoluted tubule .

7. A fall in GFR can activate the JG cells to release renin which can stimulate the glomerular blood flow and thereby the GFR back to normal.

8. Nearly 99 percent of the filtrate is reabsorbed by the renal tubules. This process is called reabsorption.

9. For example, substances like glucose, amino acids, Na+, etc., in the filtrate are reabsorbed actively whereas the nitrogenous wastes and water are absorbed by passive transport.

10. During urine formation, the tubular cells secrete substances like H+, K+ and ammonia into the filtrate.

11. Tubular secretion is helpful in the maintenance of ionic and acid-base balance of body fluids.

Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination

Function Of The Tubules
Proximal Convoluted Ttubule (PCT):
1. PCT consists of simple cuboidal brush border epithelium which increases the surface area for reabsorption.

2. All essential nutrients, and 70 – 80 per cent of electrolytes and water are reabsorbed by this segment.

3. PCT also helps to maintain the pH and ionic balance of the body fluids. It occurs through selective secretion of hydrogen ions, ammonia and potassium ions into the filtrate and by absorption of HCO3 from it.

Henle’s Loop
Function:
It helps to maintain high osmolarity of medullary interstitial fluid. The descending limb of loop of Henle is permeable to water but impermeable to electrolytes. This concentrates the filtrate as it moves down.

The ascending limb is impermeable to water but allows transport of electrolytes actively or passively. Therefore, as the concentrated filtrate pass upward, it gets diluted due to the passage of electrolytes to the medullary fluid.

Distal Convoluted Tubule (DCT):
The reabsorption of Na+, HCO3 and water takes place in this segment. In this segment selective secretion of hydrogen and potassium ions and NH3 to maintain the pH and sodium-potassium balance in blood.
Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination 4

Collecting Duct:
It extends from the cortex of the kidney to the inner parts of the medulla. Large amounts of water is reabsorbed from this region to produce a concentrated urine. This part maintains pH and ionic balance of blood by the selective secretion of H+ and K+ ions.

Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination

Mechanism Of Concentration Of The Filtrate
The flow of filtrate in the two limbs of Henle’s loop is in opposite directions and thus forms a counter current. The flow of blood through the two limbs of vasa recta is also in a counter current pattern.

The proximity between the Henle’s loop and vasa recta, as well as the counter current in them help in maintaining an increasing osmolarity towards the inner medullary interstitium, i.e. from 300 mOsmolL-1 in the cortex to about 1200 mOsmolL-1 in the inner medulla. This gradient is mainly caused by NaCl and urea.

NaCl is transported by the ascending limb of Henle’s loop which is exchanged with the descending limb of vasa recta. NaCl is returned to the interstitium by the ascending portion of vasa recta. Similarly, small amounts of urea enterthe thin segment of the ascending limb of Henle’s loop which is transported back to the interstitium by the collecting tubule.

This transport is facilitated by the counter current mechanism This mechanism helps to maintain a concentration gradient in the medullary interstitium. Presence of such interstitial gradient helps in an easy passage of water from the collecting tubule thereby concentrating the filtrate (urine).

Regulation Of Kidney Function
The functioning of the kidneys is influenced by hypothalamus, JGA and to a certain extent, the heart in the body are activated by changes in blood volume.

How can diuresis is prevented in body?
The decrease of fluid from the body can activate these Osmoreceptors which stimulate the hypothalamus to release antidiuretic hormone (ADH) or vasopressin from the neurohypophysis. ADH facilitates water reabsorption Hence it prevents diuresis.

An increase in body fluid volume switch off the osmoreceptors and suppress the ADH release. ADH can also affect the kidney function by its constrictory effects on blood vessels. This causes an increase in blood pressure. An increase in blood pressure increase the glomerular blood flow and the GFR.

A fall in glomerular blood flow/glomerular blood pressure/GFR can activate the JG cells to release renin which converts angiotensinogen in blood to angiotensin I and further to angiotensin II. Angiotensin II, increases the glomerular blood pressure and thereby GFR.

Angiotensin II also activates the adrenal cortex to release Aldosterone. Aldosterone causes reabsorption of Na+ and water from the distal parts of the tubule. This also leads to an increase in blood pressure and GFR. This is known as the Renin-Angiotensin mechanism.

An increase in blood flow to the atria of the heart can cause the release of Atrial Natriuretic Factor (ANF). ANF can cause vasodilation (dilation of blood vessels) and thereby decrease the blood pressure. ANF mechanism acts as a check on the renin-angiotensin mechanism.

Micturition
It is the voluntary signal from the central nervous system (CNS). This signal is initiated by the stretching of the urinary bladder in response to the stretch receptors on the walls of the bladder.

The process of release of urine is called micturition and the neural mechanisms causing it is called the micturition reflex. An adult human excretes 1 to 1.5 litres of urine per day.

The urine is slightly acidic (pH – 6.0) and has a characterestic odour. 25 – 30 gm of urea is excreted out per day. Analysis of urine helps to know malfunctioning of the kidney.

For example, presence of glucose (Glycosuria) and ketone bodies (Ketonuria) in urine are indicative of diabetes mellitus.

Role Of Other Organs In Excretion
Lungs remove large amounts of CO2 (18 litres/day) and water every day. Liver secretes bile-containing substances like bilirubin, biliverdin, cholesterol, degraded steroid hormones, vitamins and drugs.

The sweat and sebaceous glands in the skin eliminates watery fluid containing NaCl, small amounts of urea, lactic acid, etc. Sebaceous glands eliminates sterols, hydrocarbons and waxes through sebum. This secretion provides a protective oily covering for the skin.

Plus One Zoology Notes Chapter 8 Excretory Products and their Elimination

Disorders Of The Excretory System
Uemia:
It leads to the accumulation of urea in blood. It lead to kidney failure. In such patients, urea can be removed by a process called hemodialysis.

Procedure of Dialysis:
Blood drained from a artery is pumped into a dialysing unit after adding an anticoagulant like heparin.The unit contains a coiled cellophane tube surrounded by a fluid (dialysing fluid).

The porous cellophane membrance allows the passage of molecules based on concentration gradient.
As nitrogenous wastes are absent in the dialysing fluid, the cleared blood is pumped back to the body through a vein after adding anti-heparin to it.

Remedy for kidney damage:
Kidney transplantation is the ultimate method in the correction of acute renal failures (kidney failure). A functioning kidney is used in transplantation from a donor to minimise its chances of rejection by the immune system of the host.

Renal calculi:
Stone or insoluble mass of crystallised salts (oxalates, etc.) formed within the kidney.

Glomerulonephritis:
Inflammation of glomeruli of kidney

NCERT SUPPLEMENTARY SYLLABUS
Diabetes Insipidus:
Antidiuretic hormone (ADH) is released from the posterior pituitary, prevents dehydration. It helps in the reabsorption of water by the distal parts of the kidney tubules and prevents diuresis. Deficiency of ADH leads to diabetes insipedus, that means huge amounts of dilute urine is formed followed by intense thirst.

The name itself (diabetes = overflow; insipidus = tasteless) distinguishes it from diabetes .mellitus (mel = honey), in which insulin deficiency causes large amounts of blood sugar to be lost in the urine

Artificial kidney:
Hemodialysis machine is known as the artificial kidney. Hemodialysis is an artificial process of removing toxic substances from the blood in patients of kidney failure.

Kerala Plus Two Accountancy Notes Chapter 5 Dissolution of Partnership

Summary
Dissolution of Partnership Firm
When the partnership between all the partners of a firm comes to an end it is called dissolution of partnership firm. When the firm is dissolved, it leads to the closure of the business – firm’s book of accounts are closed, assets of the firm realised, liabilities are paid off and whatever remains is paid to the partners in settlement oftheir accounts.

Dissolution of Partnership
When the relation of partnership among different partners changes without affecting the entity of the firm, it is called dissolution of partnership. Dissolution of partnership takes place in the case of admission, retirement, death etc. This does not necessarily involve dissolution of partnership firm.

Accounting treatment
The following accounts are prepared on dissolution.

Realisation account
Realisation account is a nominal account prepared for the purpose of closing the accounts of assets and liabilities and for finding out the profit or loss on realisation of assets and payment of liabilities. The profit or loss on realisation is transferred to partners’ capital accounts in their profit sharing ratio.

Capital accounts of partners
Each, partner’s capital account is credited with accumulated profit and realisation profit, if any, and debited with accumulated loss and realisation loss. After making any other adjustments, as per agreement, the balance in the capital account represents the amount due to or due from each partner. Partners’ capital accounts are closed by paying off orbringing in cash, as the case may be.

Kerala Plus One Physics Notes Chapter 14 Oscillations

Introduction
In this chapter, we study oscillatory motion. The description of an oscillatory motion requires some fundamental concept like period, frequency, displacement, amplitude and phase.

Periodic And Oscillatory Motions
Periodic Motion:
A motion that repeats itself at regular intervals of time is called periodic motion.
Example:

  • The orbital motion of planets in the solar system.
  • The piston in a steam engine going back and forth

Oscillations or Vibrations:
A body executes to and fro motion at regular intervals of time is called oscillatory (or) vibratory motion.

Note:
(1) When the frequency is small, we call it oscillation. When the frequency is high, we call it vibration.
Period and frequency:
Period (T):
Time taken to complete one oscillation is called period

Frequency (n):
The number of oscillations per second is called frequency.
frequency v = \(\frac{1}{T}\)Hz

Plus One Physics Notes Chapter 14 Oscillations

Displacement:
Displacement of oscillation means the change of any physical property with time under consideration.

Explanation:
For example, consider the oscillation of block attached to a spring. In this case the displacement of block with time is referred to as displacement.

In the case if oscillation of simple pendulum, the angle from the vertical as a function of time may be regarded as a displacement variable. The voltage across a capacitor, changing with time in an a.c. circuit is also a displacement variable

Note:
The displacement variable may take both positive and negative values.

Simple Harmonic Motion And Uniform Circular Motion

Question 1.
Show that the projection of uniform circular motion on any diameter of the circle is S.H.M.
Plus One Physics Notes Chapter 14 Oscillations 6
Answer:
Consider a particle moving along the circumference of a circle of radius ‘a’ and centre O, with uniform angular velocity w. AB and CD are two mutually perpendicular diameters along X and Y axis. At time t = 0. let the particle be at P0 so that ∠P0OB = Φ.

After time Y second, let the particle reach P so that ∠POP0 = ωt. N is the foot of the perpendicular drawn from P on the diameter CD.

Plus One Physics Notes Chapter 14 Oscillations

Similarly M is the foot of the perpendicular drawn from P to the diameter AB. When the particle moves along the circumference of the circle, the foot of the perpendicular executes to and fro motion along the diameter CD or AB with O as the mean position. From the right angle triangle O MP, we get
cos (ωt + Φ) = \(\frac{\mathrm{OM}}{\mathrm{OP}}\)
∴ OM = OP cos (ωt + Φ)
X = a cos (ωt + Φ) ………………. (1)
Similarly, we get
sin (ωt + Φ) = \(\frac{y}{a}\) (or)
Y = a sin (ωt + Φ) ……………… (2)
Equation (1) and (2) are similar to equations of S.H.M. The equation(1) and (2) shows that the projection of uniform circular motion on any diameter is S.H.M.
At t = 0, if the particle is at B, then Φ = 0. Then equations (1) and (2) reduce to
x = a cos ωt ………………….. (3)
y = a sin ωt …………………….(4)

Velocity And Acceleration In Simple Harmonic Motion B
Velocity Of S.H.M.
The y displacement of S.H.M. is given by
y = a sin ω t
∴ velocity in y direction
Plus One Physics Notes Chapter 14 Oscillations 7

Case – 1
At the mean position y=0, therefore velocity is maximum. The maximum velocity is given by
Plus One Physics Notes Chapter 14 Oscillations 8
Case – 2
At the extreme position, y = a
∴ Vminimum = \(\sqrt{a^{2}-a^{2}}\) = 0
So the velocity of a S.H.M. varies between o and wa

Acceleration of S.H.M
We know y = a sin ω t
Velocity v = \(\frac{d y}{d t}\) = a ω cos ω t
Acceleration a = \(\frac{d^{2} y}{d t^{2}}\) = -aω² sin ωt
a = -aω² sin ωt

Force Law For Simple Harmonic Motion
According to Newton’s second law of motion F = ma
But a = -ω²y(t)
ie. force acting on the S.H.M. in Y direction
F = -mω²y(t)
(or) F = -ky(t)
Where k= mω²
From the above equation (1), we can take an alternative definition of simple harmonic motion.

Statement:
Simple harmonic motion is the motion executed by a particle subject to a force, which is proportional to the displacement of the particle and is directed towards the mean position.

Energy In Simple Harmonic Motion
A simple harmonically moving particle possesses both potential energy and kinetic energy. Potential energy is due to its displacement against restoring force. Kinetic energy is due to its motion.

Total energy of the S.H.M. is the sum of the kinetic energy and potential energy. Total energy remains a constant throughout its motion.

Consider a mass m suspended from one end of a string of length L fixed at the other end as shown in figure. Suppose P is the instantaneous position of the pendulum. At this instant its string makes an angle θ with the vertical.

The forces acting on the bob are (1) weight of bob Fg (mg) acting vertically downward. (2) Tension T in the string.

Periodic oscillations of decreasing amplitude due to the presence of resistive forces of the medium are called damped oscillations.

Question 2.
Derive a differential equation for a damped simple harmonic oscillation.
Plus One Physics Notes Chapter 14 Oscillations 24
Answer:
Consider a block of mass ‘m’ connected to one end of a massless spring of spring constant K. The other end of spring is connected to rigid support. The block is connected to a vane through a rod (The vane and rod are massless). The vane is submerged in a liquid.

Let the equilibrium position of block be ‘O’. If this block is moved along downward direction through a distance x, a damping force will be developed on vane due to liquid. This damping force is proportional to velocity of vane ie; damping force Fd α – v (or) Fd = -bv

where b is called damping constant. The value of b depends on the characteristics of the liquid and the vane.

Plus One Physics Notes Chapter 14 Oscillations

The restoring force on the block due to spring. Fs = -kx. where x is the displacement of the mass from its equilibrium position.
∴ Total force on the block, F = -bv + -kx
ma = -bv + -kx
ma + bv + kx = 0
\(m \frac{d^{2} x}{d t^{2}}+b \frac{d x}{d t}+k x=0\)

Case – 2
If b is small, the amplitude of the oscillator decreases continuously with time. The motion is approximately a periodic. The Variation of displacement x (t) with time T is shown below.

Note:
Small damping means that the dimensionless ratio
\((b / \sqrt{k m})\) is much less than 1.

Forced oscillations and resonance
Free oscillation:
When a body oscillates in the absence of external forces (eg. friction etc.) the oscillations are said to be free oscillations.

Forced oscillation:
When an external periodic force is applied to a damped harmonic oscillator, the oscillator will vibrate with a constant amplitude and frequency of vibration will be that of the applied periodic force. This type of oscillation is called forced oscillation.

The differential equation of forced oscillator:
Let F(t) = F0 cosωdt is an external force applied to a damped oscillator.

The total force acting on the damped oscillator,
F = – bv – kx + F0 cosωdt
where -bv is the damping force and -kx is the linear restoring force.
F + bv + kx = F0 cosωdt
\(m \frac{d^{2} x}{d t^{2}}+b \frac{d x}{d t}+k x=F_{0} \cos \omega_{d} t\)
This is the differential equation of an oscillator of mass m on which a periodic force of (angular) frequency ωd is applied. The oscillator initially oscillates with its natural frequency w. When we apply the external periodic force, the oscillation with the natural frequency die out, and the body oscillates with the (angular) frequency of the external periodic force.

The motion of forced oscillator:
The solution (displacement) of the above differential equation of forced oscillator can be written as
x(t) = Acos(ωdt + Φ)
Plus One Physics Notes Chapter 14 Oscillations 32
where m is the mass of the particle v0 and x0 are the velocity and the displacement of the particle at time t = 0, (which is the moment when we apply the periodic force)

Case -1
When b = 0 (damping force = 0) and ω = ωd,
we get A = \(\frac{F_{0}}{0}\)
A = ∞
This is an ideal case. This case never arises in a real situation as the damping is never perfectly zero.

Case – 2
(Small damping, driving frequency far from natural frequency).
In this ωdb << m(ω² – ωd²). Hence we can neglect ωdb. Hence amplitude of oscillation can be written as.
Plus One Physics Notes Chapter 14 Oscillations 33

Case – 3
(Small damping, driving frequency close to natural frequency).
In this case m(ω² – ωa²) << ωdb. Hence we can neglect m (ω² – ωa²). Hence amplitude of oscillation can be written as
Plus One Physics Notes Chapter 14 Oscillations 34

This equation shows that the maximum amplitude fora given driving frequency is governed by the driving frequency and damping constant.

Plus One Physics Notes Chapter 14 Oscillations

Resonant Oscillation
When the frequency of the external periodic force is varied, it is found that the amplitude of the forced vibration increases and reaches a maximum value and then decreases.

The amplitude will be maximum when the frequency of the applied periodic force is equal to the natural frequency of the vibration. Such oscillations are called resonant oscillations and the phenomenon is called resonance.

Graphical variation amplitude with driving frequency:
Plus One Physics Notes Chapter 14 Oscillations 35

Examples of resonance:
All mechanical structures have one or more natural frequencies, and if a structure is subjected to a strong external periodic driving force that matches one of these frequencies, the resulting oscillations of the structure may rupture it.

The Tacoma Narrows Bridge at Puget Sound, Washington, USA was opened on July 1, 1940. Four months later winds produced a pulsating resultant force in resonance with the natural frequency of the structure.

This caused a steady increase in the amplitude of oscillations until the bridge collapsed. It is for the same reason the marching soldiers break steps while crossing a bridge. Aircraft designers make sure that none of the natural frequencies at which a wing can oscillate match the frequency of the engines in flight! Earthquakes cause vast devastation.

In an earthquake, short and tall structures remain unaffected while the medium height structures fall down. This happens because the natural frequencies of the short structures happen to be higher and those of taller structures lower than the frequency of the seismic waves.

Kerala Plus Two Accountancy Notes Chapter 4 Reconstitution of a Partnership Firm – Retirement/Death of a Partner

Summary
Retirement of a partner
A partner’s withdrawal from the business with the consent of other partners or as per the provisions of the partnership deed or by giving notice of retirement is called retirement of a partner.

Accounting problems on retirement
Accounting problems that arise on the retirement of a partner are as follows
(a) New profit sharing ratio:
It is the ratio in which the remaining partners will share future profits after the retirement of any partner.
New share = Old share + acquired share from outgoing partner.

Plus Two Accountancy Notes Chapter 4 Reconstitution of a Partnership Firm - Retirement/Death of a Partner

(b) Gaining Ratio:
The ratio in which the continuing partners decide to share the outgoing partner’s profit is called gaining ratio.
Gaining ratio = New ratio – Old ratio

(c) Treatment of goodwill:
A partner who is retiring from the firm is entitled to his share of goodwill. It is fair and equitable to compensate the retiring partner for the respective share of goodwill by the continuing partners in their gaining ratio.

I. When goodwill does not appear in the books.
A. Goodwill is raised at its full value and retained-in the books as such. The journal entry is,

Plus Two Accountancy Notes Chapter 4 Reconstitution of a Partnership Firm - Retirement/Death of a Partner

Death of a Partner:
Death, being a natural phenomenon, may take place at any time. A partnership comes to an end on the death of any one of the partners, although the firm may continue with the remaining partners. The accounting treatment for various adjustments in case of death of a partner is similar to that of a retiring, partner.

According to Section 37 of the Partnership Act, the executors of the deceased partner are entitled, at their choice, to interest at 6% p.a. on the amount due, from the date of death till the date of payment or that portion of profit earned by the firm with the help of the amount due to the deceased partner.

The amount due to the deceased partner may be paid off immediately to his legal heirs, or executors. Whenever a firm is not in a position to make the final payment immediately in cash, the same is transferred to his executor’s loan account. The Journal entry will be:

Kerala Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm – Admission of Partner

Summary
Reconstitution of a partnership firm
Reconstitution of a partnership firm means a change in the nature of relationship amongst members, effected through a fresh agreement under which the existing business continues.

Mode of reconstitution
Reconstitution of a partnership firm usually takes place in any of the following ways:

  1. Change in the profit sharing ratio of the existing partners
  2. Admission of a partner
  3. Retirement of a partner
  4. Death of a partner

Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner

Admission of a partner
Inclusion of a person as partner to an existing partnership firm is called admission of a partner. Acquisition of rights by a new partner:

  1. right to share the assets of the firm
  2. right to share profits/losses of the firm

Accounting problems at the time of admission

  1. Capital of new partner
  2. Calculation of new profit sharing ratio
  3. Calculation of sacrificing ratio
  4. Treatment of goodwill
  5. Revaluation of assets and liabilities
  6. Adjustment of reserves and accumulated profits/ losses
  7. Adjustment of capital accounts of partners

New profit sharing ratio
The ratio in which the old partners and new partner share the future profit after the admission is new ratio.
New ratio = old ratio – sacrificing ratio

Sacrificing ratio
The ratio in which the old partners agree to sacrifice their share of profit in favour of the incoming partner is called sacrificing ratio.
Sacrificing ratio = old ratio – New ratio

Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner

Goodwill
Goodwill is the value of the reputation of a firm in respect of profits in future over and above the normal profits. It is an invisible intangible asset. Thus goodwill really arises only if a firm is able to earn super profit.
Treatment of goodwill (Different situations):

  1. Premium paid directly
  2. Premium brought in cash and retained in business
  3. Premium brought in cash and half the amount withdrawn by partners
  4. Premium brought in kind
  5. New partner brings in only a portion of the goodwill in cash
  6. New partner is not in a position to bring premium in cash
  7. Goodwill existing in the books at the time of admission

Methods of valuation of goodwill:
1. Average profit method:
Goodwill = \(\frac{\text { Total profit }}{\text { No. of years }}\) × No. of years purchase

2. Super profit method:
Normal Profit = Cap employed × \(\frac{N R R}{100}\)
Average Profit = \(\frac{\text { Total profit }}{\text { No. of years }}\)
Super profit = Average profit – Normal profit
Goodwill = Super Profit × No. of years purchase

3. Capitalisation method:
(a) Capitalising the average profit:
Goodwill = Capitalised value of average profit – capital employed – Total assets (excluding goodwill) – outside liabilities
Capital employed = Total Asset – Outside liabilities.

(b) Capitalisation of superprofit
Goodwill = Super profit × \(\frac{100}{\mathrm{NRR}}\)

Treatment of goodwill:
Premium method – When the new partner brings cash for his share of goodwill.
(i) When this amount is paid directly/ privately to the old partner by new partner.
No entry is needed.

Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner

(ii) When the amount is paid through firm
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 1
To Old partner’s capital A/c (Sacrificing Ratio)

(iii) When the old partners decide to withdraw their amounts (full or part)
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 2
When goodwill already exists in books, the existing goodwill must be written off by debiting the old partners in their old ratio.
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 3
If they decide to retain goodwill as such, the amount to be brought in by the new partner will have to be proportionately reduced.

Revaluation of Assets and Reassessment of liabilities
Assets and liabilities are revalued at the time of admission. The account opened for this purpose is called revaluation account. The Journal entries recorded for revaluation of assets and reassessment of liabilities are as follows:
1. For increase in the value of an asset
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 4

2. For reduction in the value of an asset
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 5

3. For appreciation in the amount of a liability
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 8

4. For reduction in the amount of a liability
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 9

5. For an unrecorded asset

Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 12

8. For transferring loss on revaluation
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 13

Adjustment for reserves and accumulated Profits/Losses
Items like reserve and accumulated profits/losses appearing in the balance sheet should be distributed to old partners at the time of admission of a partner.
1. Reserve and Profit & Loss A/c if any on the liability side of balance sheet Reserve A/c Dr.

2. Profit & Loss A/c on the asset side of balance sheet
Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner 7

Plus Two Accountancy Notes Chapter 3 Reconstitution of a Partnership Firm - Admission of Partner

Adjustment of capital accounts of partners
It may sometimes be agreed that the capitals of all partners should be in proportion to their respective share in profits. This can be effected in two ways:

  1. Adjustment of old partners’ capital accounts on the basis of incoming partner’s capital
  2. Bringing in proportionate capital by the incoming partner based on the capitals of existing partners.

Change in profit sharing ratio
Sometimes, the existing partners may decide to change their profit sharing ratio. In such a case, those who gain must compensate the others who have made the sacrifice on account of change in profit sharing ratio.

Spreadsheet – Meaning
Spreadsheet application is a computer program that allows to record, calculate and compare numerical or financial data. Using a spreadsheet program. We can store a lot of data in the worksheet and also arrange and analyse the data by using different functions and formulae for meaningful object.

It is used to establish relationship between two or more sets of data. Libre Office Calc, MS Office Excel, Open Office Spreadsheet etc. are examples of spreadsheet software.

Plus Two Accountancy Notes Chapter 2 Spread Sheet

Features of Spreadsheet

  1. A spreadsheet is a configuration of rows and columns.
  2. A spreadsheet is also known as worksheet.
  3. Spreadsheet application allows to enter (ie., add) and process data.
  4. It makes quick and easy financial and numerical analysis of data.
  5. The data stored in the spreadsheet can be converted into graphs, charts etc.
  6. It can be used to store, arrange and filter data.

Introduction to Libre Office Calc
Libre Office Calc is one of the best spreadsheet applications, which can be used to calculate, analyse and manage data. It is a Free and Open Source Software (FOSS). Libre Office Calc is available for a variety of platforms including Linux, OSX, Microsoft windows and Free BSD.
1. Features of Libre Office Calc:

  • It is a spreadsheet application.
  • It is both free software and open source software.
  • It can be used to calculate, analyse and manage data.
  • The worksheet in Libre Office Calc contains Rows and Columns in a Table format.

Basic concept of Libre Office Calc Spread Sheet
(a) Workbook:
A file in spreadsheet is known as a workbook. A work book is a collection of a number of work sheets.

(b) Work sheets:
The work area which consists of rows and columns in a spreadsheet is called worksheet. By default three worksheets – sheet-1, sheet-2, sheet-3 are available in work book.

(c) Active work sheet:
The worksheet which is available to the user for carrying out operations is called active work sheet. The name of the active worksheet will be shown in bold letters in the Sheet Tab at bottom of work sheet.

(d) Sheet Tab:
It shows the name of the work sheet at bottom left of the screen. Additional sheets can be added by clicking on the right hand side of the sheet Tab.

Plus Two Accountancy Notes Chapter 2 Spread Sheet

(e) Rename:
The Sheet-1, Sheet-2, and Sheet-3 etc. can be renamed by right clicking the mouse over the worksheet and selecting “Rename” option.

(f) Rows:
Rows are the horizontal vectors in the worksheet. These are numbered numerically
from Top to Bottom.

(g) Columns:
Columns are vertical vectors in the worksheet. These are referred by alpha characters from left to right such as A, B, C, …, AA, AB, AC …etc.

(h) Cell:
The intersection of a row and a column is called a cell. A cell is identified by a combination of an alpha – numeric character eg: A1, B6, C10, etc. This alpha numeric character is called cell address. Hence each cell has a unique address.

(i) Active cell:
When we start Libre Office Calc, the pointer (cursor) points the first cell ie., A1, and this cell is called the active cell. The active cell is distinguished by a dark box called cell pointer. We can move the cell pointer by using the arrow keys UP, DOWN, LEFT and RIGHT.

(j) Cell Reference:
A cell reference identifies location of a cell or group of selected cells in spreadsheet.

(i) Types of Cell References:
1. Relative Cell references:
By default cell reference is relative; which means that as a formula or function is copied and pasted to other cells, the cell references in the formula or function change to reflect the new location.

2. Absolute Cell reference:
The absolute cell reference consist of the column letter and row number surrounded by dollar ($) signs. Eg $A$5. An absolute cell reference is used when we want a cell reference to stay fixed on a specific cell.

Plus Two Accountancy Notes Chapter 2 Spread Sheet

3. Mixed cell reference:
It is a combination of relative and absolute cell references that holds either row or column constant when the formula or function is copied to another location.

(k) Inserting Rows and Columns:
We can add or delete Rows and Columns in a spreadsheet. To add column, click at the column header (right click on the mouse) there we get an option to add column.

Likewise, we can add rows. To delete the column, click the column header (right click on the mouse) there we get an option to delete column. Likewise we can remove rows.

(l) Ranges:
Range is a group of adjacent cells that forms a rectangular area. A range is specified by giving the address for first cell in range and the last cell in the rage, eg: range starting from A10 to A20 is written asA10:A20 where colon (:) is the range operator.

(m) Spreadsheet navigation:
We can move around a worksheet through four arrow keys. ie;

  • Left arrow key
  • Right arrow key
  • Up arrow key
  • Down arrow key

The mouse can also be used for navigation in spreadsheet except data entry. Some common operations/navigations are listed below:

Movement Key stroke (Press Key)
One cell up Up arrow key/Shift+Enter key
One cell down Down arrow key/ Enter key
One cell right Right arrow key/Tab key
One cell left Left arrow key/Shift + Tab key
Top of sheet (Cell A1) Ctrl + Home Key
Move to last cell containing data Ctrl + End Key
Move to beginning of the Row Home Key or Ctrl+Left arrow key
Move to last filled cell in column End key

Plus Two Accountancy Notes Chapter 2 Spread Sheet

(n) Labels:
A descriptive information for rows or columns in the form of a text, or a special character is called Label.
Eg: Name, Roll No, Address

(o) Formula:
The formula means a mathematical calculation on a set of cells. The formula must start with an = (equal to) sign. When a cell contains a formula, it often contains reference to other cells.
Eg: = Basic pay + DA + HRA.

Spreadsheet Functions
Functions:
A function is a special key word which can be entered into a cell in order to perform and process the data which is appended within brackets. There is a function button f(x) on the formula bar.

When we click on it, function offers assistance through Function Wizard. Alternatively we can enter the function directly into the formula bar. A function is a build in set of formulae which starts with an ‘equal to sign’ (=).
Eg =SUM (), =AVERAGE (), =COUNT() etc.
There are twelve different categories of functions available in LibreOffice Calc. Important functions are

  • Date and Time Function
  • Financial Function
  • Logical Function
  • Mathematical Function
  • Look Up and Reference Function
  • Statistical Function

Date and Time Functions
These functions are used for inserting, editing and manipulating date and time. “Date” must be entered with quotation marks. Libre Office Calc internally handleds a date/time value as a numerical value. The most commonly used Date and Time Functions are:

1. TODAY ():
It is the function for today’s date in the worksheet. This helps to update the date value when we reopen the spreadsheet or modify the values of the document.
Syntax: =TODAY()

2. NOW ():
It is the function for today’s date and present time. This helps to update the date and the time value when the cell value is modified.
Syntax: =NOW()

3. YEAR ():
It helps to update the year for the given date value
Syntax: = YEAR (Date value) or = YEAR (“Date”)

Plus Two Accountancy Notes Chapter 2 Spread Sheet

4. MONTH ():
It helps to update the month for the given date value. The month is recorded as an integer between 1 and 12.

6. DATEVALUE ():
This function converts the given date into the corresponding date number. By default 31/12/1899 has the value as 1.
Syntax: =DATEVALUE (“Date”)

7. DATE ():
This function calculates a date specified by year, month, day and displays it in the cell’s formatting.
Syntax: = DATE (Year; Month; Day)

Mathematical Functions
The following mathematical functions are very useful in business applications.

1. SUM ():
This function adds all the numbers in a range of cells. The AutoSum (S) button can also be used directly for summation of values from cells.
Syntax:=SUM (number 1, number 2,…….)

2. SUM IF ():
It returns the sum of the cells as per a given criteria.
Syntax: = SUMIF (range, “criteria”, sum_range) where

  • Range is the range of cells to evaluate.
  • Criteria defines which cells will be added.
  • Sum_range, is the range from which values are summed.

3. ROUND ():
This function rounds a number to specified number of digits or decimal places.
Syntax: = ROUND (Number, Count)
Plus Two Accountancy Notes Chapter 2 Spread Sheet 1

Plus Two Accountancy Notes Chapter 2 Spread Sheet

4. ROUNDUP():

Statistical Functions
Statistical function operates on a set of data and give summarised results. Libreoffice Calc provides a number of statistical functions. They are

1. COUNT ():
This function used to count the number of cells in a range contains numbers only.
Syntax :=COUNT(Value 1, Value2,…)
or := COUNT (Range)

2. COUNTA():
This function used to count the number of ceils In a range contains any value. It will count number, text, time, date, logical values, error code, etc. In other words, this function counts the number of cells that are not empty in a range.
Syntax: = COUNTA (Value 1, Value 2….) or = COUNTA (Range)

3. COUNTBLANK():
This function in LibreOffice Calc count the number of empty cells in the given range. It is the opposite function of COUNTA.
Syntax: =COUNTBLANK (Range)

4. COUNTIF():
This function counts the number of cells within a given range that meet the criteria or condition.
Syntax: COUNTIF (Range, Criteria)

5. ROWS():
This function returns the number of rows in a reference or array.
Syntax = ROWS (Array)
Where Array is the reference or named area whose total number of rows is to be determihed.

Plus Two Accountancy Notes Chapter 2 Spread Sheet

6. Columns ():
This function returns the number of columns in an array or reference
Syntax: = COLUMNS (Array)
Where Array is the reference to a cell range whose total number of columns is to be found.

Text Manipulation Function
There are two types of Text Manipulation Functions in LibreOffice Calc. They are

1. TEXT ( ):
This function converts a number or I numerical value into text according to a defined format.
Syntax: TEXT (Number, Format)
This function is useful in situations to display numbers in a more readable format.

2. CONCATENATE ( ):
This function is used to combines several text strings in different cells into one string.
Syntax:=CONCATENATE (“Text 1 ”, “…..”,“ Text n”)

Logical Functions
Logical functions are used for comparison and checking a test condition. The major logical functions are IF, AND and OR.

1. IF ():
This function is used to test a condition. When the condition is TRUE, then first action is taken. When it is FALSE, then the second action is taken.
Syntax: IF (Test, Then value, Otherwise value)

2. NESTED IF ()
Libre Office Calc allows to include one function inside another function. It is called nesting of functions. The IF function can be nested, when you have multiple condition to meet.
Syntax: =IF (Test_1, Then value_1, If (Test_2, Then value _2, If (_____)))

3. AND ():
This function gives only a TRUE or FALSE answer.
Syntax: =AND (Logical value 1, Logical value 2,…)

4. OR ():
Returns TRUE if atleast one argument is TRUE. This function returns the value FALSE, If all the arguments have the logical value FALSE
Syntax: = OR (Logical value 1, Logical value 2,…)

Plus Two Accountancy Notes Chapter 2 Spread Sheet

Spreadsheet Reference Functions
The important spreadsheet reference functions are

1. LOOKUP () functions:
The LOOKUP function returns a value either from a one-row or one-column range or from an array. The lookup function has two syntax forms: Vector form and Array form.

The vector form of LOOUP looks in a one-row or one-column range (known as a vector) for a value, and then returns a value from the same position in a second one-row or one-column range.

The array form of LOOKUP looks in the first row or column of an array for the specified value, and then returns a value from the same position in the last row or column of the array.

  • LOOKUP (Vector from)
    Syntax: =LOOKUP (search criterion, Search vector, Result vector)
  • LOOKUP (Array form)
    =(LOOKUP (lookup_value, array)

2. VLOOK UP ():
VLOOK UP is the vertical LOOKUP function. Use VLOOK UP to search the first column (columns are vertical) of a block of data and return the value from another column in the same row.
Syntax: = VLOOKUP (Search criterion; Array; Index; Sort Order)

3. HLOOKUP ( ):
It is the Horizontal LOOKUP function, searches for a value in the first row of a table array and returns the corresponding value in ‘ the same column from another row of the same table array.
Syntax: -HLOOKUP (search criteria; index; sorted)

Financial Functions
The major financial functions of LibreOffice Calc are discussed below:

1. ACCRINT ():
This function returns the accrued interest for a security that pays periodic interest.
Syntax:= ACCRINT(Issue, First_nterest, settlement, rate, Par, frequency, basis, calc_method)

2. CUMIPMT():
This function returns the cumulative interest paid between two periods.
Syntax: = CUMIPMT (Rate, NPER, PV, S, E, Type)

3. PV():
This function is used to calculate the amount of money needed to be invested at a fixed rate today, to receive a specific amount, over a specified number of periods.
Syntax: = PV (Rate, NPER, Pmt, FV, Type)

4. PMT ():

Data Entry, Text Management, and Cell Formatting
In any computerised business application, the basic requirement is to input data, which may be either for processing or to update various data elements. In both the cases, data should be correct, accurate and should be in proper format.

Data Entry
Libreoffice Calc facilitates fast data entry. Some of the methods for data entry are mentioned below:

1. The data fill options:
The ‘fill’ command can be used to fill data into worksheet cells. To fill quickly in several types of data series, we select cells and drag the fill handle (A fill handle is the small black square in the lower-right corner of the selection). When we point to the fill handle, the pointer changes to + symbol.

2. Import/Copy Data from other sources:
This method will transfer data into required cells by copying or importing an external file to calc sheet.

3. Data validation:
This is a feature to define restrictions on type of data entered into a cell. We can configure data validation rules for cells data that will not allow users to enter invalid data. There may be warning messages when users tries to type wrong data in the cell.

Data Formatting
Formatting of spread sheets makes easier to read and understand the important information. On the Ribbon there are several tools and shortcuts to format spreadsheets effectively. Some of them are explained below.

1. Number formatting:
Number formatting includes adding percent symbols (%), commas(,), decimal places (.), and currency signs (?) date (dd/mm/yyyy), time (HH: mm), scientific values and as well as some special formats to a spreadsheet.

2. Currency:
If we enter a financial value with the currency sign, calc assigns a currency format to the cell along with the entry.

3. Dates:
If we enter the date, that follows one of the built-In Calc number formats, such as 01/06/2018 or 01 June 2018, the program assigns a Date format that follows the pattern of the date.

4. Changing cell colours:
Select the range to format. From the Toolbar, select format and click on cells to display format cells dialog box and choose background tab. The back ground tab provide Background colourforthe cell. Select the desired colour from the colour pallets. Then click OK to make necessary changes.

5. Create a custom cell border:
We can create a cell style that includes a custom border, and can apply to that cell style when we want to display the custom border around selected cells.

  • Select the properties option on the side bar (Right)
  • Click cell appearance
  • We can modify cell border properties

6. Conditional formatting:
We can apply conditional formatting to a cell range, a table, or a Pivot Table report. A conditional format changes the appearance of a cell range based on a condition or criteria. If the condition is true, the cell range is formatted based on that condition; if the condition is false, the cell range is not formatted based on that condition.

Changing The Alignment Of Data In Cells
There are several options to change the alignment of text (Data) in cells.

1. Text Formatting:
We can format the text in the cell in the following way.

  • The font style can be changed
  • The font size can be changed
  • If we need bold letters, Italics, or underlined, choose from appropriate field.
  • The back ground colour can be changed
  • The text alignment in the cell either is left, right, center or justify
  • The position in the cell ie., Top, Center or Bottom of the cell can be selected.
  • The borders to the cell can choose from the appropriate field.
  • Different types of borders can be given in the field.

All these actions are also given in property windows appears on the right of the work sheet.

2. Merging a range of cells:
Merged cells are’ a single cell that is created by combining two or more selected cells. When two or more adjacent horizontal or vertical cells are merged, the cells become one large cell and displayed across multiple columns or rows. The contents of cell appear in the centre of the merged cell.

3. Split a merged cell:
Select the merged cell which we want to split into two. When we select a merged cell, the merge and centre button also appears selected in the Alignment group on the Home Tab. Click merge and centre.

4. Formatting a table:
There are predefined table styles or quick styles that we can use to quickly, format a table. Select cells where the Table hasto be inserted. Then select the format option in the menu bar, in the dropdown menu select the auto format. We can select the predefined table format.

5. Headers and Footers:
In calc spreadsheet, headers and footers are lines of text that are printed at the top (Header) and bottom (footer) of each page in the menu bar. They contain descriptive text such as titles, dates, and / or page numbers and are used to add information to a printed spreadsheet. These options are available under insert option in the menu bar.

Output Reports
We can print entire or partial worksheets and work books, one at a time, or several at once.

1. Page set Up:
We can customize our output Report by editing the page set up option.

2. Print Out:
Before Printing, we have to verify print preview which gives an idea about how the print out may come. The modification can be done by this verification.

3. Defining the Print:
By default, Libre Office Calc prints all data on the current worksheet. The print area can be customized/defined by using Dialog Box option.

4. Preparation of reports using Pivot Tables:
A Pivot Table is a way to present information in a report format. A PivotTable report provides enhanced layout, attractive and formatted report with improved readability. There are two types of data table.

  • One-Variable Data Table
  • Two-Variable Data Table

The one variable Data Table allows us to identify a single decision variable in our model and see how changing the values for that variable affect the values calculated by one or more formulas in our model.

The two variable Data table allows us to Specify two decision variables and a variety of inputs and only a single formula.

Kerala Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves

Summary:
Meaning of depreciation:
Depreciation is decline in the value of a tangible fixed asset. In accounting depreciation is the process of allocating depreciable cost over useful life of a fixed asset.

Depreciation and similar terms:
Depreciation term is used in the context of tangible fixed assets. Depletion (in the context of extractive industries), and amortisation (in the context of intangible assets) are other related terms.

Factors Affecting Depreciation:

  • Wear and Tear due to use and/or passage of time
  • Expiration of Legal Rights
  • Obsolescence

Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves

Importance of depreciation:

  • Depreciation must be charged to ascertain true and fair profit or loss.
  • Depreciation is a non-cash operating expense.

Methods of charging depreciation:
Depreciation amount can be calculated using:

  • Straight line method, or
  • Written down value method

Methods of recording depreciation:
In the books of account there are two types of arrangements for recording depreciation on fixed assets.

  • Charging depreciation to asset account or
  • Creating provision for depreciation/ accumulated depreciation account.

Charging depreciation to asset account:
According to this arrangement depreciation is deducted from the depreciable cost of the asset (credited to the asset account) and charged (or debited) to profit and loss account. Journal entries under this recording method are as follows:
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 1

2. Following two entries are recorded at the end of every year.
(a) For deducting depreciation amount from the cost of the asset.
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 2

(b) For charging depreciation to profit and loss account
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 3

3. Balance Sheet Treatment
When this method is used, the fixed asset appears at its net book value (ie. cost less depreciation charged till date) on the asset side of the balance sheet and not at its original cost (also known as historical cost).

Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves

Creating Provision for depreciation account/ Accumulated depreciation Account:
This method is designed to accumulate the depreciation provided on an asset in a separate account generally called “Provision for Depreciation” or “Accumulated Depreciation” account.

The following journal entries are recorded under this method:
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 4

2. The following two journal entries are recorded at the end of each year
(a) For crediting depreciation amount to provision for depreciation account.
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 5

(b) For charging depreciation to profit and loss account
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 6

3. Balance Sheet treatment
In the balance sheet the fixed asset continues to appear at its original cost on the asset side. The depreciation charged till that date appears in the provision for depreciation account, which is shown either on the “liabilities side” of the balance sheet or by way of deduction from the original cost of the asset concerned on the asset side of the balance sheet.

Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves

Disposal of Asset:
Disposal of asset can take place either

  • At the end of its useful life or
  • During the useful life (due to absolescence or any other abnormal factors). In this case the following journal entries are recorded.

1. For the sale of asset as scrap
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 7

2. For transfer of balance in asset account
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 8

In case, however “the provision for depreciation account” has been in use for recording the depreciation, then before passing the above entries transfer the balance of the provision for depreciation account to the asset account by recording the following journal entry.
Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves img 9

Factors affecting the amount of depreciation:

  • Depreciation amount is determined by Original cost
  • Salvage value, and
  • Useful life of the asset

Provisions and Reserves:
A provision is a charge against profit. It is created for a known current liability the amount of which is uncertain. Reserve on the other hand, is an appropriation of profit. It is created to strengthen the financial position of the business.

Plus One Accountancy Notes Chapter 6 Depreciation, Provisions and Reserves

Types of Reserves:
Reserves may be:

  • General reserve and specific reserve;
  • Revenue reserve and capital reserve.

Secret Reserve:
When the total depreciation charged is higher than the total depreciable cost, the Secret reserve is created. The secret reserve is not explicitly shown in the balance sheet.

Interest on capital
Interest on capital payed to partner’s as a compensation for their capital contribution to the firm. It is allowed at an agreed rate on the amount of capital (at the beginning and on additions) with reference to time.

Interest on drawing
Interest to be charged on the withdrawals made by the partners if it has been specifically metioned in the partnership deed. It is calculated with reference to time at an agreed rate on the amount of withdrawal.
Calculation of interest on drawings under different situations
(I) When the amount is withdrawn every month
(a) When the amount is withdrawn at the beginning of each month:
Average period = 6.5 months
Interest on drawings = Total drawings × \(\frac{6.5}{12} \times \frac{\text { Rate }}{100}\)

(b) When the amount is withdrawn at the end of each month
Average period = 5.5 months
Interest on drawings = Total drawings × \(\frac{5.5}{12} \times \frac{\text { Rate }}{100}\)

(c) When the amount is withdrawn in the middle of the month.
Average period = 6 months
Interest and drawings = Total drawings × \(\frac{6}{12} \times \frac{\text { Rate }}{100}\)

(II) When fixed amount is withdrawn quarterly
(a) If the amount is withdrawn at the beginning of each quarter.
interest on drawings= Total drawings × \(\frac{7.5}{12} \times \frac{\text { Rate }}{100}\)

(b) If the amount is withdrawn at the end of each year
Interest on drawings = Total drawing × \(\frac{4.5}{12} \times \frac{\text { Rate }}{100}\)

Plus Two Accountancy Notes Chapter 2 Accounting for Partnership - Basic Concepts

(III) When varying amounts are withdrawn at different intervals.
Interest on drawings = Sum of Product × \(\frac{Rate}{100} \times \frac{\text {1 }}{12}\)
Sum of Product = Withdrawal amount × Remain-ing months in the year.

Guarantee of profit to a partner
Sometimes, on admission of a new partner, the existing partners may give an assurance to the incoming partner that he shall be given a minimum amount of profit irrespective of the firm’s actual profits. This is called guarantee of profit to a partner.

The guarantee may be given either by all the partners or by one of the partners. If the share of profit of the new partner is more than the guaranteed amount, then he will get his actual share of profit.

Past Adjustments
Sometimes, after closing the books of accounts it is found that certain items are left out by mistake or have been wrongly treated. In such a case necessary adjustments are carried out in partners’ capital accounts through an account called ‘profit and loss adjustment account’.

Preparation of final accounts of a partnership firm
There is not much difference in the final accounts of a sole trading concern and that of a partnership firm. The only difference is the division of profit among the partners for which a profit and loss appropriation account has to be prepared.
