Question 12.
In the open market, the price of rice/kg is ₹ 35. Assume that the poor people cannot afford to purchase rice at this price. To protect the poor people, the government decided to offer rice at a minimum price of ₹ 2/kg through ration shop. Identify the economic term of this situation. Draw a diagram to illustrate this.
Answer:
Price selling:

In the diagram, ‘ep’ is the market determined equilibrium price. If this price is very high then the government will interfere in the market and will fix ‘p’ as the price ceiling. This government fixed price ‘p’ is less than the market determined equilibrium price ‘ep’. This leads to the following situations.

• Black marketing
• Dual marketing
• Huge burden of government as subsidy.

Answer:

Question 20.
a) Distinguish between MPC and MPS.
b) Calculate the value of multiplier and income generated when there is an additional investment of ₹ 100 crore in an economy.

Question 22.
QD = 500 – P
QS = 300 + P
a) Calculate the equilibrium price and quantity.
b) Draw a diagram based on equilibrium price and quantity.
Answer:
a) QD = 500 – P
QS = 300 + P
500 – P = 300 + P
500 – 300 = +P + P
200 = 2P
\(\frac{200}{2}\) = P
P = 100
Equilibrium price is 100
QD = 500 – P
= 500-100 = 400
Equilibrium quantity = 400

b)

Question 25.
a) Mention the methods of National Income accounting and explain briefly the expenditure method.
b) Caculate the GNP MP from the following data:

Answer:
a) There are mainly three methods for measuring national income. They are product method, income method and expenditure method.
i) Product method: It is the sum of the gross value added by the entire production units in the economy.
GDP = \(\sum_{i=i}^{N} N V A_{i}+\sum_{i=i}^{N} D_{i}\)

ii) Income method: The income method approaches national income from the income side. National income is the sum total of the rewards earned by the factors of production in an economy in the form of rent, wage, interest and profit.
GDP = W + P + In + R

iii) Expenditure method: Expenditure method is an alternative way to calculate the GDP and it looks at the demand side of the production. The expenditure method estimates national income by measuring final expenditure on gross domestic product.
GDP = C + I + G + X – M

b) GNP_MP = 18000
= 5000 + 1000 + 2000 + 10000
= 18000

Question 28.
In a perfectly competitive market, the firm wishes to maximize its profit.
a) Identify the conditions with the help of a diagram.
b) Explain the profit maximization of a firm in the short run.
c) In the long run, a perfectly competitive firm earns the normal profit. Do you agree with this? Graphically substantiate.
Answer:
a) The main air of a firm under perfect competition is the maximization of profit. The output level at which the firm maximises its profits is called equilibrium of the firm. The following conditions are necessary for the profit maximization. If firm

Condition – 1
Market price (P) should be equal to MC. ‘P’ should not be greater than MC or ‘P’ should not be less than MC.

If the market price (P) is less than MC then for producing each unit of output the firm incurs loss. When the firm produces output at q0 the gross profit is maximum. If q0 is equilibrium output then at q0 level of output market price (P) should be equal to MC.

Condition – 2
At the profit maximising level of output MC should not be decreasing or MC curve should cut MR curve from below.

Condition – 3
In the short run the price (P) should be more than or equal to minimum point of AVC.

Here the equilibrium output is q₁ and equilibrium price is p. If the price line is aboue the minimum point of AVC the loss will decrease. Thus in the short run the price of the firm should be more than or equal to minimum point of AVC.

b) Profit of a firm can be denoted as π. It is the difference between total revenue and total cost. Profit maximisation of firm in the short run takes place through following situations in the market which are given below.
1) P = MC
2) MC curve should cut the MR curve from below.
3) P > AVC.
In the short riff the firm should get at least minimum point of AVC as price, inorder to remain in the production process. So the minimum point of AVC is known as shut down point in the short run. In the short run the minimum point of SAC curve is the break even point.

c) Yes. I agree with this statement.
Each firm in the market will take the price determined in the market by the forces of demand and supply. If a firm changes a higher price than the market determined price then it will loose its entire customers. Since the firm gets only the normal profit he cannot sell below the market determined price.

Question 29.

a) Write down the equation for calculating Revenue deficit, Fiscal deficit and Primary deficit.
b) Calculate Revenue deficit, Fiscal deficit and Primary deficit from the given data.
c) Suggest any two measures to reduce the Fiscal deficit in the country.
Answer:
Revenue deficit = Revenue expenditure – Revenue receipts
Fiscal deficit = Total expenditure – Total revenue excluding borrowing
OR
Fiscal deficit = Total expenditure – Revenue receipt + Capital receipts excluding borroiwng
Primary deficit = Fiscal deficit – Interest payments

b) Revenue deficit = 65000 – 50000 = 15000
Fiscal deficit = 90000 – 50000 – 15000
= 90000 – 65000 = 25000
Primary deficit = 25000 – 10000
= 15000

c) 1) Reduction in subsidies by the government will also help to reduce the deficit.
2) Borrowing from domestic sources
