3. Answer : (b)
Reason : On a straight-line demand curve elasticity of demand at any
point is equal to lower segment of the demand curve / upper
segment.
Option (a) is incorrect as elasticity of demand at midpoint is
equal to one.
Option (b) is correct as elasticity of demand falls as we move
down the demand curve.
Option (c), (d) and (e) are incorrect as elasticity of demand
falls as we move down the demand curve.

4. Answer : (c)
Reason: When a decrease in price leads to increase in quantity
purchased so much as to increase the total revenue, the price
elasticity of demand is more than unity.
< TOP

5. Answer : (a)
Reason : The demand curve is Qd = 200 – P
The quantity demanded is Q = 200 – 75 => Q =125
Therefore dQ/dP = -1 (the slope)
Therefore point elasticity of demand = dQ/dP×P/Q
Therefore, Ed = -1 ×(75/125)= - 0.6.
< TOP
>
6. Answer: (a)
Reason : Demand : 20 = 104 – 4Q
4Q = 84
Q = 21
Supply : 20 = 2 + 0.5Q
0.5Q = 18
Q = 36
Surplus : 36 – 21 = 15 units.
< TOP
>
7. Answer : (b)
Reason : When tax is imposed, buyer and seller share the tax based on
the opposite ratios of their elasticities. Thus,
Ed = -80P/Q
Es = 40P/Q
Ratio of Es: Ed = 1: 2
Burden on consumer = 12 x 1/3 = 4
Earlier equilibrium price: 5,800 – 80P = 1,000 + 40P
4800 = 120P
P = 40
< TOP

Thus, new price = 40 + 4 = Rs.44.
8. Answer : (d)
Reason : Q = 10,000 – 1500(5) + 2(5000) + 200(8)

Income elasticity of demand: dQ/dY × Y/Q = 2 ×
5000/14100 = 0.709
< TOP
>
9. Answer : (e)
Reason : a. False. A consumer tends to maximize total utility (TU)
rather than marginal utility (MU). TU will be maximum
when MU is equal to the price paid by the consumer. If
the MU is greater than the price, the consumer can
increase TU by consuming more of the good. If MU is
less than the price, the consumer can maximize TU by
decreasing consumption of the good.
b. False. Apart from tastes and preferences (indifference
map), price of the product and income level of the
consumer (budget line) also determine how much of a
good a consumer will buy.
c. False. If magnitude of increase in demand is greater
than the magnitude of increase in supply, price will
increase. On the other hand if increase in supply is
greater than the increase in demand, price will decrease.
d. False. If the good under consideration is an inferior
good, increase in income would cause the demand to
fall.
e. True price and quantity demanded is inversely related
for normal goods.
< TOP
>
10. Answer : (c)
Reason : The demand curve of the consumer can be derived from the
price consumption curve. A price consumption curve
represents the successive points of tangency between the
different budget lines and the indifferent curves. Each point
on the (PCC) represents a price and quantity combination.
By plotting these price-quantity combinations, we can get the
corresponding point on the demand curve.

11. Answer : (d)
Reason : When the management of a company has increased the salary
of the staff by 10%, it will not affect the implicit cost.
Implicit cost incurred by a firm is actually the opportunity
cost of the factor owned by him. Opportunity cost of any
input is the next best alternative use that is sacrificed by its
present use. It indicates what a factor can earn in the next
best use.
(a) Is not answer because when there is an increase in
salary of the staff by 10%, economic cost increases.
(b) Is not answer because when there is an increase in
salary of the staff by 10%, accounting profit decreases.
Because accounting profits is the firm’s total revenue
less its economic cost. So when the economic cost
increases, accounting profits decreases.
(c) Is not answer because when there is an increase in
salary of the staff by 10%, direct cost increases.
Because direct costs are costs which can be directly
contributed to production of a given product.

diminishing marginal productivity’.
e. Average fixed cost (AFC = TFC/Q) falls at a decreasing
rate with the increase of output because of constant total

26. Answer : (e)
Reason : Least-cost production implies that the producer produces a
given level of output where the marginal physical product to
the factor price ratio is equal to the factor inputs.
a. It is not appropriate in this instance because it is
indicating that all factor prices are equal indicates the
demand and supply of that factor.
b. It is not appropriate in this instance because it indicates
the addition to total output by the employment of an
additional unit of a factor of production all else equal.
c. It is not appropriate in this instance because marginal
physical product is the slope of the total output curve
and therefore will not indicate the least cost production.
d. It is not appropriate in this instance because it is not
indicating the least-cost-production.
e. It is appropriate in this instance because, it is the change
in the total revenue of the firm that results from the
employment of one additional unit of a factor of
production. Therefore the marginal physical product to
factor price ratio equal to the factor inputs indicates the
least-cost production. The correct answer is (e).

Reason : In the short run a firm cannot avoid fixed costs. Whether the
firm undertakes production or not the fixed costs are incurred
by the firm. Therefore, the deciding factor for the firm is
whether it is able to recover its variable costs or not. As long
as the revenue (price) is greater than the variable (average
variable) cost it is in the interest of the firm to undertake
production.

Reason : Perfect competition is a form of market structure which
represents a market without rivalry among the individual
firms. The characteristics of perfect competition are: Large
number of buyer and sellers Homogeneous product No
barriers to entry Perfect information Perfect mobility of
factors of production. There are large number of buyers and
the demand curve which is the marginal revenue curve is
horizontal to the x-axis implying that the producer can
produce as much as the quantity of output for a given level of
price. All the additional goods can be sold at the market price
only, hence in a perfect competition, P = MR = AR. Hence

Or, Q = 2850/1.5 = 1900 units.
< TOP
>
33. Answer : (b)
Reason : A firm will shut down its operations if the price is less than
average variable cost. Since under perfect competition, price
is also equal to marginal revenue, the firm will continue
operations in the short run so long as price is at least equal to
average variable cost. Thus the minimum price, which the
firm will shut down, is the minimum average variable cost.
AVC = 300 – 40Q + 2Q2 Minimum average variable cost:
∂ AVC/ ∂ Q = 0 Thus, -40 + 4Q = 0 Or, Q = 10 When the
firm is producing 10 units, then AVC = 300 – 40(10) +
2(100) = 100.Thus, if price falls below Rs.100.

consumption curve. Hence the option is true.
MPS refers to change in savings as results of change in
income and slope of consumption curve gives the changes in
consumption as a result of change in income. Hence not true.

61. Answer : (a)
Reason : As the purchasing power of rupee decreases in future, due to
inflation, the real value of money paid by the borrowers to
the lender would be less. If inflation is anticipated, the lender
would include them in the interest rate.
a. An unexpected increase in inflation makes the borrower
to pay back money that has less real value than was
expected. As nominal interest rates do not include
unexpected inflation, real interest rate would be less
than the expected rate. Thus, borrower will be benefited
from unanticipated inflation.
b. Fixed income earners get only fixed nominal income.
With the inflation, the real value of money received
decreases. Hence they are losers during inflation.
c. Inflation reduces the purchasing power of the rupee
held and thereby reduces the value of rupee held by the
currency holders.
b. Because of unexpected increase in inflation the lender
receives money from the borrower which has a lesser
real value than expected. Interest rate on loans only
comprises expected inflation. Thus, lenders would
suffer from unexpected inflation by quoting less interest
rate than it should have been.

money supply and easing the liquidity in the banking system
easy credit is made available for productive endeavor. A
reduction in cash reserves increase lend able resources of
banks. The correct answer is C – along with it, reduction in
bank rate and buying government securities stimulate the
economy. Devaluation is undertaken in an extreme case of a
persistent deficit in BOP.
(a) Is not the answer because increase in bank rate is a
contractionary monetary policy.
(b) Is not the answer because increase in cash reserve ratio
is a contractionary monetary policy
(c) Is the answer because reduction in cash reserve ratio is

an expansionary monetary policy
(d) Is not the answer because selling government securities
in open market is not an expansionary monetary policy
(e) Is not the answer because devaluation of the currency is
not an expansionary monetary policy.
63. Answer : (a)
Reason : Automatic stabilizers refer to those government spending and
tax revenues that change automatically as the economy
fluctuate. This prevents aggregate demand from falling
excessively during bad times and rising during good times.
National defense spending is not an automatic stabilizer
because it is less concerned with the ups and downs in the
economy.
a. National defense spending changes depending upon the
security situation and not on the business cycles. Thus,
national defense spending does not signify an automatic
stabilizer.
b. Social welfare payments are made during economic
downturns that prevent aggregate demand from falling
excessively during economic downturn. But, once the
economy picks up the social welfare payments will
decrease which prevent aggregate demand from rising
excessively.
c. Unemployment compensation payments increase during
the economic downturn because of higher rate of
unemployment caused by reduced business activity.
Unemployment compensation payments prevent
aggregate demand from falling excessively during
economic downturn. On the contrary, these payments
will be low no sooner than the economy picks up. This
prevents aggregate demand from rising excessively.
d. & (e) tax revenues automatically change depending
upon the profits generated by the firms. It would be
lower during downturn and higher during boom.

64. Answer : (c)
Reason : Consumption function for an economy is estimated to be c =
400 + 0.75 Yd
Y = C + S
When S = 0, Y = C
∴ Y = 400 + 0.75 Y
or, 0.25Y = 400
Yd = 1,600
∴ c = 400 + 0.75 ( 1,600) = 400 + 1,200 = Rs.1,600 cr.

65. Answer : (c)
Reason : Money supply (Ms) = High-powered money (H) {(1 +
Cu)/(Cu + r)}
Where Cu = currency deposit ratio
R = cash reserve ratio.
H = Monetary liabilities (ML) +
Government money
{(1 + Cu)/(Cu + r)} = Money multiplier
When the cash reserve ratio (CRR) is reduced, the money
multiplier increases and hence the money supply.
a. Monetary liabilities of the Central Bank consist of
currency with the public, reserves of commercial banks
and other deposits. Changes in the CRR do not affect

monetary liabilities of the RBI because decrease in
reserves is offset by the increase in currency with the
public. Hence, monetary liabilities remain the same for
a given change in CRR.
b. As monetary liabilities are part of high-powered money,
hence changes in the CRR do not affect the highpowered
money also.
c. Money multiplier = {(1 + Cu)/(Cu + r)}. Hence
decrease in the CRR increases the value of the money
multiplier.
d. Money supply in the economy increases with the cut in
the CRR because of increase in the value of money
multiplier. When money supply increases, the interest
rates in the economy falls, leading to increase in
consumption and investment. This results in increase in
aggregate demand in the economy.
e. When money supply increases because of reduction in
the CRR, the aggregate demand in the economy
increases. Higher aggregate demand leads to higher
price levels in the country.
66. Answer : (d)
Reason : Outside lag ’is the duration involved for output and
employment to respond to changes of the implemented of
policies. Taxes has the least outside lag.
(a) Is not the answer because cash reserve ratio has not the
least outside lag.
(b) Is not the answer because bank rate has not the least
outside lag
(c) Is not the answer because repo rate has not the least
outside lag
(d) Is the answer because tax has the least outside lag.
(e) Is not the answer because open market operation has
not the least.

69. Answer : (c)
Reason : The periodic upswings and down swings in the level of
economic activity which forms a regular pattern with an
expansion of activity followed by a contraction ,succeeded
by further expansion are referred to as business cycles.
Certain features characterize each of the phases.
(a) Mere existence of unemployment cannot be taken, as an
indicator of recession or depression, as in a country like
India, even though the economy is growing these is
unemployment. Hence not true.
(b) Price levels are only an indicator of purchasing power,
which in turn is dependent on income levels of the
people also. Hence cannot be taken as primarily
indicator of the different phases of business cycles.
(c) By definition, a business cycle is a swing in total
national output; income and employment market by
contraction or expansion in many sectors of the
economy changes in real GNP brings changes in prices,
employment. Hence only the basis of changes in real
GDP different phases is classified. Hence real GDP is
the correct option.
(d) Changes in inventory level do give an indication about
the different phases, but the changes inventory levels
are as a result of changes in real GDP.
(e) Gross investment is dependent on future growth rate,
which again based on estimation of real GDP in future.
Hence gross investment cannot be primarily indicator.

71. Answer : (d)
Reason : Velocity of money =
Total expenditure(PY)
Money supply (M)
Total expenditure = C + I + G = 1000+340+280 =

72. Answer : (a)
Reason : High powered money = monetary liabilities + government
money = 10,500 + 1,500 = 12,000
Ms = H ×{( ) ( )} u u 1+ C / C + r
48,000 = 12,000 {(1+ 0.25)/ (0.25 + r )}
= (1 + 0.25)/(0.25 + r) = 4
= 1 + 4r = 1 – 0.25
4r = 0.25
r = 0.0625 = 6.25%.

73. Answer : (c)
Reason : Change in foreign exchange reserves = Current account
balance + Capital account balance
Current account balance = (116,320 + 230,010 + 4000 +
1000) - (140,240 + 125,234 + 2000) = 351330 – 267474 =
83856 i.e. current account surplus (Credit)
< TOP

26
Thus, change in foreign exchange reserves = 83856 +
202,000 = 285856 MUC.
74. Answer : (a)
Reason : Ms = High-powered money x {(1 + Cu)/(Cu + r)}; where
High powered money = monetary liabilities of the central
bank + government money.
ΔMs = ΔH. m
When foreign exchange reserves of the country decline by
Rs.200 MUC, the monetary liabilities also fall by 200 MUC.
Thus, money supply decline by 4.8 x 200 = 960.

75. Answer : (c)
Reason : Y = C + I+ G
Y = 70 + 0.75Yd + 80 + 70
Y = 70 + 0.75 (Y – 0.2 Y)+ 80 + 70
Y = 70 + 0.75 Y – 0.15 Y+ 80 + 70
Y = 220 – 0.6Y
Y = 550
∴ Budget deficit = T – G = 0.2 (550) – 70 = 110 – 70 = 40

77. Answer : (a)
Reason : Intermediation Ratio = Secondary issues/New issues
Or, secondary issues = Intermediation ratio x New issues =
0.7 x 30,000 = 21,000 MUC
Total issues = New issues + Secondary issues = 30,000 +
21000 = 51,000 MUC
Financial Interrelations Ratio = Total issues/Net Physical
Capital Formation (NPCF)
= 51000 /42500 = 1.2.
