Explain any two central problems of economy re-gaining the allocation of resources.
Answer:
All economies in the world address almost same issues related to economic affairs, these issues are known as central problems of an economy they are (two problems)
1. What to produce
2. How to produce
1. What to produce:
Every economy needs lakhs of goods and services. Since the resources are scarce, all these goods and services cannot be produced. That’s why the question What to produce’ arises. So it is very Important to decide what to produce before the production starts.
2. How to produce:
This problem is related to the selection of production technique. Economies can select their production technique which suits best. They can choose labour intensive technique or capital intensive technique.

Question 22.
With the help of a diagram analyse the ‘Law of vari able proportion’.
Answer:
Short run production function is known as law of variable proportion or law of returns to a factor. Here only one factor is variable and all other factors are fixed. This law is otherwise known as law of diminishing marginal product. It explains the situation. when more and more units of variable factors are added to fixed factors then total product and marginal product will pass through three stages. They are
1. Increasing returns to a factor
2. Diminishing return to a factor
3. Negative returns to a factor

(1) Stage I : Increasing returns to a factor From the graph we can understand that total product, marginal product and average products are increasing s more variable factors are added. Here in this stage marginal product reaches its maximum.
(2) Stage II : Diminishing returns to a factor Here in this stage total product increases but at a decreasing rate. Both MP and AP declines and marginal product becomes zero, when variable inputs increases.
(3) Stage III : Negative returns to a factor In this stage, total product starts declining, marginal product becomes negative and average product continues to decline but it never becomes zero.

Question 25.
Explain any two reasons why GDP cannot be considered as an index of the welfare of the people
of a country.
Answer:
GDP is the money value of final goods and services produced by a nation during a financial year. Nation with high GDP is considered as the best, so we can say that GDP is considered as an index of development but it has certain drawbacks that’s why we cannot consider GDP as a best index of the welfare of the people.
Reasons:
1. Inequality in the distribution of income.
Along with increase in GDP inequalities in income may occur. Even if the majority does not experience any increse in income, the GDP will increase if the income of a minority increases. Here welfare diminishes even when GDP increases.
2. GDP and harmful goods.
While calculating GDP all goods and service are considered. Whether these goods and services are useful or harmful to the people is not taken into consideration. An increase in the production of such harmful products will result in an increase in GDP. But overconsumption of such harmful products result in loss of welfare, eg:-Alcohol, Tubacoo products.

Question 26.
The diagram shows the relationship between Aver age Cost (AC) and Marginal Cost (MC) curve:

i) Write short notes on:
a) Average Cost (AC)
b) Marginal Cost (MC)
ii) With the help of above diagram identify any two relationships between Average Cost (AC) and Marginal Cost (MC).
Answer:
(i) a) AC (Average cost) Cost per unit of out put is known as average cost
AC = \(\frac{\mathrm{TC}}{\mathrm{Q}}\)
b) MC (Marginal cost)
It is the change in total cost per unit change in output
MC = \(\frac{\Delta \mathrm{TC}}{\Delta \mathrm{Q}}\)
(ii) a) In the initial stage both MC and AC are diminishing (decreasng)
b) MC equals AC at the minimum point of AC.
Question 27.
With the help of diagrams anale ‘Prive Ceiling’ and ‘Price floor’.
Answer:
‘Price ceiling’
It is the upper limit on the price of goods and services imposed by the government to protect the interest of consumers (ie. protection from high price)

Here in the diagram P0 is equilibrium price which is higher, Pc is the ceiling price fixed by government which is lower than P0.
‘Price floor’
It is otherwise known as support price, it is the minimum price fixed by government to protect the interest of the producers.

Here in the diagram P0 is equilibnum price which is very low. To ensure fair pnœ government fixes floor price above the equilibnum price (P0). It is the floor price.

B. Answer any 2 questions from 30 to 32. Each carries 6 scores. (2 × 6 = 12)
Question 30.
i) What do you mean by Price Elasticity of Demand(PED)?
ii) Graphically explain the perfectly elastic and perfectly inelastic demand curves.
Answer:
i) Price elasticity of demand It is the degree of responsiveness of quantity demanded of a commodity with respect to change in tis price. It is obtained by dividing the percentage change in quantity demanded by the percentage change in price. On the basis of degree of change in the quantity demand, elasticity can be classified into a five types, they are
- Elastic demand
- Unitary elastic demand
- Inelastic demand
- Perfectly elastic demand
- Perfectly inelastic demand.
ii) Perfectly elastic demand

When a small change in price leads to infinite change in demand, this type of demand elasticity is known as perfectly elastic demand. Here the value of elasticity is infinite; demand curve would be parallel to x axis.
Perfectly inelastic demand

Here in this case price has no effect on demand, so the value of elasticity is zero. In this case demand curve is a vertical straight line parallel to y axis.
Question 31.
RBI publishes figures for four alternative measures of money supply.
i) Elucidate four measures of Money Supply in India.
ii) Identify Narrow Money and Broad Money.
Answer:
a) Supply of money in our nation is entirely controlled by RBI. RBI publishes four different measures of money supply under the heads M1 M2, M3 and M3
M1 = CU + OD ie currency notes and coins held by the public + net demand deposits of the people held by commercial banks.
M2 = M1 + saving deposits with post office – savings banks.
M3 = M1 + Net time deposits of commercial banks
M4 = MM3 + Total post office deposits except national savings certificates
b) Here M1and M2 are known as narrow money
M3 & M4 are known as broad money has thethighest liquidity M4 has least liquidity.

Question 32.
i) Distinguish between open economy and closed economy.
ii) Product market is one of the linkages through which open economies establish economic relation with rest of the World. Explain the other two linkages.
Answer:
(i) Open economy
An economy which has economic relations with other countries through exchanging goods and services financial assets etc. can be termed as an open economy. This type of economy will function freely without much regulations and control.
Closed economy
An economy without economic relations with other countries through exchanging goods and services financial assets etc. can be termed as a closed economy.
(ii) This openness can be attained through different types of linkages (ie. – connections) They are:
- Product market linkage
- Financial market linkage
- Factor market linkage
Financial market linkage:
Through this investors can invest in domestic economy and foreign economy; this will result in creation of a friendly environment and co-operation at global level.
Factor market linkage:
This means factors of production are transferable between nations. This will improve the relationship between different nations in the world.

Question 33.
i) Mention the properties of Indifference curves.
ii) Diagrammatically explain the optimal choice of consumer.
Answer:
i) Indifference curve:
It is the locus of points of combinations of two goods which give same level of satisfaction to the consumer.

Features of indifference curve.
- Indifference curve slopes downwards from left to right.
- Indifference curve is convex to origin.
- Higher indifference curves represent higher levels of satisfaction.
- Indifference curves do not intersect each other
ii) Optimal choice of the consumer
A consumer prefers a situation where his satisfaction is maximum. According to indifference curve approach, a consumer attains equilibrium at the point where budget line is tangent to highest possible indifference curve.

Here in the diagram point ‘E’ shows optimal choice of the consumer.
Question 34.
With the help of diagrams analyse the profit maximisation conditions of a firm under perfectcomPetition in short run.
Answer:
Perfect competition. It is a market situation where large number of buyers and sellers operate freely perfect competition is anextreme form of market which is rarely existing in the real world.
Features of perfect competition.
- Large number of buyers and sellers
- Homogenous products
- Perfect mobility of factors of production
- Perfect know’edge of market condition
- Freedom of entry and exit
- Absence of transport cost
- Uniform price
- Absence of selling cost
- Firms are price takers.
Short run equilibrium
Conditions of equilibrium.
1. P = MC
2. MC curve should cut MR curve from below.
3. Price should be greater than or equal to AVC
Diagrammatic representation of equilibrium

The above given diagram represents short run equilibrium under perfect competition.
Here TR = OPAQ
TC = OEBQ
Profit = TR – TC
ie. OPAQ – OEBQ = EPAB
Question 35.
What do you mean by GDP? Explain any two methods of calculating GDP.
Answer:
a) GDP
Money value of all final goods and services produced by a nation during a financial year is known as national income (GDP). Computation of national income is an important activity. To compute national income we can use three different methods, they are
1. Product method or value added method
2. Expenditure method or out lay method
3. Income-method
b) Product method or value added method
Here in this method national income is calculated by adding all the final goods and services produced by all production units in a nation during a financial year. But it is not so easy because the final output produced by a firm is used as input in other firms this problem Is termed as double counting. To avoid this problem value added method is used to calculate final value of output. As per value added method, GDP is the sum of gross value added by all the producers in the domestic territory.
2. Income method
Under his method GDP is calculated by adding together all the factor income received by the owners of factors of production, such as land, labour, capital and entrepreneurship. Therefore as per income method the GDP of an economy is the sum total of wages, rent, interest and grossprofit. ie.GDP = W +R + l + P
