Plus Two Economics Previous Year Question Paper March 2018, 1
a) Name the curve (1) and curve (2) in the diagram
b) Write any one relationship between the two curves.
a) MP curve (1) and AP curve (2)
b) When the value of MP is greater than ‘AP’ then AP increases.
When the of MP is less than the value of ‘AP’ then AP decreases.

Question 7.
The demand and supply function of a commodity are given below:
qD = 80 – 2P
qS = 60 + 2P
Find the equilibrium price and equilibrium quantity.
At equilibrium qD = qs
80 – 2P = 60 + 2P
80 – 60 = 2P + 2P
20 = 4P
qD = 80 – 2p = 80 – 2 × 5 = 80 – 10 = 70
equilibrium price = 5
equilibrium quantity = 70

Question 8.
Following data shows the level of total expenditure of an economy during a particular year. Calculate GDPMP

Items ₹ in crores
a) Private final consumption expenditure (C) 6,500
b) Government consumption and investment expenditure (G) 5,000
c) Private Final Investment Expenditure (I) 4,000
d) Export (X) 600
e) Import (M) 900

GDPMP = C + I + G + (X – M)
= 6500 + 5000 + 4000 + 600 – 900
GDPMP = 15200

Question 9.
Calculate price elasticity of demand at point A and B by using geometric equation from the following linear demand curve.
Plus Two Economics Previous Year Question Paper March 2018, 2
A = |eD| > I
B = |eD| < I

Question 10.
Following data shows the money supply of an economy. Calculate M1 and M3.

Items ₹ in crores

b) Net demand deposits with commercial banks 40,000
c) Savings deposits with post office Savings Bank 1,000
d) Net time deposits with the commercial banks 3,000

M1 = Cu + DD
Cu = Currency and coins held by the public
DD = Demand deposits in commercial banks
= 20,000 + 40,000 = 60,000
M3 = M1 + Net time deposits with the commercial banks.
= 60,000 + 3,000 = 63,000

Question 15.
Graphically illustrate the determination of equilibrium exchange rate under flexible exchange rate system.
Flexible Exchange Rate
It is also known as floating exchange rate determination. Here the exchange rate is determined by the forces of demand and supply of foreign exchange. The central bank has no role in the determination of exchange rate. They do nothing to directly affect the level of the exchange rate. It can be illustrated with the help of figure.

Question 20.
Governments have mostly depend on borrowings for meeting its budgetary deficits. But this Govt, debt act as a burden on future generation. Do you agree with this statement? Substantiate.
I agree with this statement. If the government borrow more, it may lead to a situation that the private investors cannot get enough fund from the capital market for investment. This is known as crowding out effect. So this may help the private sector to borrow more in future. The government can reduce budget deficit either through increasing taxes or by reducing public expenditure.

  • Law of variable proportion
  • Some inputs kept constant

Long run production function:

  • Returns to scale
  • All inputs are variable
  • Factors are changing proportionately

Answer any 4 of the following from 22 – 27. Each carries 5 scores. (4 × 5 = 20)

Question 22.
a) Illustrate graphically the price fixation action of the government to protect the consumers from huge price rise.
b) State any two consequences of this action on consumers.
a) The price determined in the market by the forces of demand and supply is very high, the common man will find it very difficult to purchase the goods. Then the government will interfere in the market. The government will fix a price that is less than the market determined price. This is known as price ceiling.
This can be explained with the help of figure.
Plus Two Economics Previous Year Question Paper March 2018, 9
In the diagram, ‘ep’ is the market determined equilibrium price. If this price is very high then the govt, will fix price ‘p’ which is less than market price ‘ep’.

b) This leads to the following situations

  • Rationing: The government will supply goods at ‘p’ price through ration shops.
  • This may lead to huge burden to the government as subsidy.

Question 26.
Explain the relationship between TP, AP and MP in the short-run with the help of a diagram.
The three stages of returns to a factor can be explained through the following diagram.
Plus Two Economics Previous Year Question Paper March 2018, 13
First stage: The marginal product (MP) increases i.e. total product (IP) increases at an increasing rate. This stage is known stage of increasing returns to a factor.

Second stage: In this stage the marginal product decreases. Here the TP increases at a decreasing rate. This stage is known as diminishing returns to a factor.

Third stage: Here the marginal product becomes negative. Therefore the total product decreases. This stage is known as stage of negative returns to a factor.

Question 27.
Sometimes duopoly firm behave like a monopoly firm. Some other times they are competing each other. Explain the behaviour and features of Oligopoly/Duopoly firm.
The term oligopoly has derived from two terms oligo (small) and poly (seller). Thus oligopoly is a market situation characterized by a competition among few sellers. In simple terms, it is a competition among few sellers in the market selling either homogenous or differentiated product. The industries manufacturing car, motor cycle, scooter etc. are some of the examples for oligopolistic competition.

The main features of oligopolistic competition are as follows:

  • Few sellers: The number of sellers or producers would be few under oligopolistic competition.
  • Homogneous or differentiated products: The products sold under oligopolistic competition would be either homogneous (e.g. gas, petrol) or differ – entiated (e.g. car, scooter)
  • Free entry and exit: Free entry and exit persist under oligopolistic competition.
  • Selling cost: Firms spend on advertisement and sales promotion.
  • Interdependence of the firms: Since the number of firms under oligopoly are few, they are highly interdependent. The action of one firm will certainly have impact on other firms in terms of price, quality of the product, etc.
  • Price leadership: Some of the firms may emerge as price leaders under oligopoly. The price leader could be the first firm in the industry or the firm with largest number of consumers. The price leader takes the important decisions regarding the-vital decisions such as the price of the product or number of units to be produced in the market, etc.

Answer any 2 of the following from 28 – 30. Each question carries 8 scores. (8 × 3 = 24)

Question 28.
RBI reduces its rate of lending to commercial banks at 25 point basis in its third monetary policy review of 2017-18.
a) Which policy instrument is used by RBI in the above context?
b) Briefly explain the operation of any three monetary policy instruments that RBI would adopt during inflation.
c) Name the instrument that RBI often uses for stabilizing the stock of money from external shocks.
a) Bank rate policy
b) Instruments of Monetary Policy and the Reserve Bank of India.

The instruments which RBI uses for conducting monetary policy are as follows.
1) Open Market Operations: It refers to the sale and purchase of government securities by the central bank. RBI purchases government securities to the general public in a bid to increase the stock of high powered money in the economy.

2) Bank Rate Policy: As mentioned earlier, RBI can affect the reserve deposit ratio of commercial banks by adjusting the value of the bank rate – which is the rate of interest commercial banks have to pay RBI – if they borrow money from it in case of shortage of reserves. A low (or high) bank rate encourages banks to keep smaller (or greater) proportion of their deposits as reserves, since borrowing from RBI is now less (or more) costly than before.

3) Varying Reserve Requirements: Cash Re¬serve Ratio (CRR) and Statutory Liquidity Ratio (SLR) also work through the rdr-route. A high (or low) value of CRR or SLR helps increase (or decrease) the value of reserve deposit ratio, thus diminishing (or increasing) the value of the money multiplier and money supply in the economy in a similar fashion.

4) Sterilization by RBI: RBI often uses its instruments of money creation for stabilizing the stock of money in the economy from external shocks. This operation of RBI is known as sterilization.

c) Open market operations

Question 29.
a) Write down the identities of calculating GDP of an economy using three methods.
b) There are only 2 producting units, A and B in the economy. Calculate:
i) GVAMP of firm A.
ii) GVAMP if firm B.
c) Calculate GDPMP


(₹ in Crores)

i) Sales by firm A 10,000
ii) Sales by firm B 20,000
iii) Change in stock of firm B 2,000
iv) Change in stock of firm A 500
v) Purchase of raw materials by firm A 5,000
vi) Purchase of raw materials by firm B 6,000
vii) Consumption of fixed capital by firm A & B 1,800

a) GDP ≡ [latex]\sum_{i=1}^{N}\) GVAi / GVA1 + GUVA+ GVAn
≡ \(\sum_{i=1}^{N}\) RVi = C + I + G + X – M = W + P + Iu + R

b) GVAMP → A = Gross value – intermediate consumption = 5500
GVAMP → B → Equation = 16000

c) aDPMP = GVAMP pf firm A + GVAMP of firm B
= 21,500

Question 30.
a) Mr. Roy wants to buy rice and milk with the money income of ₹ 200. Its market prices are ₹ 10 and ₹ 5 respectively.
i) Derive the budget line equation.
ii) Find the slope of the budget line.
iii) Find out horizontal and vertical intercept.
b) Explain the optimum level of the consumer (Consumer’s Equilibrium) with suitable diagram.
a) i) P1X1 + P2X2 = M
10X1 + 5X2 = 200
Budget line can be taken as
Plus Two Economics Previous Year Question Paper March 2018, 14

b) The consumers equilibrium is that point at which the budget line is tangent to the indifference curve. In the diagram ‘E’ is the consumers equilibrium. The consumer will purchase the consumption bundle at the point ‘E’.
Plus Two Economics Previous Year Question Paper March 2018, 15
The points A & B does not show the equilibrium. The consumer gets more satisfaction on indifference curve IC3 than at IC2. But he cannot go to bundles on IC3 indifference curve as his budget does not allow him to do so. So the consumer will prefer bundles on the indifference curve IC2. So ‘E’ is the consumer’s equilibrium point.
