(Any three) (1x3)
7. Es = 1 if the curve starts from the origin
Es> 1 if the curve starts from the y-axis
E<1 if the curve starts from the x-axix
8. Downward sloping concave PP curve shows increasing Marginal Rate of
Transformation (MRT) as more quantity of one good is produced by reducing
quantity of the other good. This behaviour of the MRT is based on the assumption
that all resources are not equally efficient in production of all goods. As more of
one good is produced, less and less efficient resources have to be transferred to the
production of the other good which raises marginal cost i.e. MRT. (3)
The problem means that who will buy the goods produced ? Clearly those who
have income will buy. people earn income in the form of wages, rent, interest and
profit. This reduces the problem to the problem of distribution of income among
people. (3)
9. Qty. sold. Price ATC TR TC Profit
(Units) (Rs. per unit) (Rs) (Rs) (Rs) (TR-TC)
7 10 6 70 42 28
8 9 5 72 40 32
9 8 6 72 54 22
10 7 7 70 70 0 (2)
Profit maximizing output = 8 units (1)
10. Marginal revenue is the addition to total revenue from producing one more unit of
output (1)
(i) MR = AR at all the output levels (1)
(ii) MR will be less than AR at all the output levels (1)
11. (1)
- = (1½)
? 200 P = 200
or P = ?1 (½)
New P = P+ P = 5+(?1) = Rs.4. (1)
12. Monopoly :
(1) Only one producer
(2) No freedom of entry to new firms, etc.
Monopolistic Competition (1x2)
(1) Large number of sellers and buyers
(2) Firms produce diiferentiated products.
(3) Freedom of entry and exit to firms
(4) Perfect knowledge about market (any two) 1x2
Perfect competition : (1) Large number of sellers and buyers
(2) Firms produce homegeneous product
(3) Freedom of entry and exit to firm
(4) Perfect knowledge about market and technology. (1x4)
13. Increase in supply means more quantity supplied at the given price. Supply curve
shifts to the right from S1 to S2. This creates excess supply (=E, A) at price OP.
Since the firms are not able to sell what they produce, Competition among firms
leading to fall in price. takes place. Fall in price leads to rise in demand and fall in
supply. These changes continue till price falls to OP2 OP2 is the new equilibrium
price and OQ2. equilibrum quantity. (3)
For Blind Candidates in lieu of Question No. 13
Schedule (2)
Explanation (2)
Relation between ATC and AVC. (3)
1. ATC is greater than AVC by the amount of AFC. (1½)
2. The difference between ATC and AVC decreases as more output is produced
because AFC declines as level of output increases. (1½)

(c) When MC< AVC, AVC falls
15. Consumer?s equiibrium means allocation of income by a consumer on goods and
services in a manner that gives him maximum satisfaction. (2)
The two conditions of consumer?s equibrium are :
(i) Ratio of marginal utility to price in case of each good is the same i.e.
MUx = (2)
(ii) MU of a good decreases as more of it is consumed. (2)
16. (i) It means that TPP increases at an increasing rate and consequently MPP rises.
It is due to (a) more efficient utilization of fixed input and (b) division of labour
and specialisation due to increase in the quantity of variable input. (3)
(ii) It means output increasing in greater proportion than the increase in all input
simultaneously and in the same proportion. It is due to (a) more division of
labour leading to specialisation that increases produtivilty and(b) use of
specialized machines.

(ii) When there is a surplus in the revenue budget but the deficit in capital budget
is greater than this surplus (1½)

cannot be shifted. Indirect tax is a tax where burden can be shifted. (2)
Exampls : Direct Tax : Income Tax etc................. (½)
Indirect Tax : Excise duty etc............... (½)
24. (a) It is a capital receipt as it results in reduction of asset.
(b) It is a capital receipt as it creates liability.

(ii) Saving account deposits (½)
Interest is paid on deposits is this account. (½)
(iii) Fixed/ term deposits (½)
Interest paid on such deposits is higher than the interest paid on deposits under
saving account (½)
27. In current account, transactions relating to export and import of goods and services (3)
and transfer payment are recorded. In capital account transaction relating to
international purchases and sales of assets are recorded.
Import of machinery is included under import of goods and so it is recorded under (1)

28. The central bank acts as a banker to the government. The government keeps its cash
balance with the central bank. The central bank accepts receipts and makes payments
for the government. It also provides short term credit facility to the government.
It also manages the public debt. It also advises the government on banking and
financial matters. (4)
(a) Money is acceptable as means of exchange. A person can sell his goods or
services in exchange for money and can use this money for buying the goods and
services that he needs. Thus money acts as a medium of exchange, (2)
(b) Deferred payments mean payments to be made in future. Money serves as a
standard for deferred payments. Money can perform this function only if its value
remains more or less stable. (2)
29. (a) YI
= K =
1000 =
MPS = 0.25
\MPC = 0.75
So MPC = 0.75 (1)
(b) D S = D Y x MPS
= 1000 x 0.25
= Rs. 250 Crores (1)
(c) D C = D Y x MPC
= 1000x0.75
= Rs. 750 Crores (1)
K = = 4 (1)
30. Expenditure method estimates expenditure on domestic product, i.e expenditure on
final goods and services produced within the economic territory of the country. It
includes expenditure by residents and non- residents both. Exports, though purchased
by non- residents, are produced within the economic territory, and therefore, a part
of domestic product. (4)
Domestic product can be greater than national product if factor income paid to the
rest of the world is greater than the factor income received from the rest of the world
is i.e. when net-factor income received from abroad is negative. (2)
31. The equilibrium level of income and output is that level at which planned saving and
planned investment are equal. (1)
ss? is the saving curve that shows planned saving at diffrent levels of income. I I?
shows fixed level of investment as it is assumed that investment is given and is
constant, OQ is the equilibrium level of income and output as at this level, planned
saving and investment are equal (2)
If planned expenditure is less than planned output inventories will increase. So output
will be reduced till planned expenditure and planned output are equal.
Same as above except diagram
For Blind candidates
32. Income method
National Income = (iv+viii) + (iii + ix) + xi+xiii - x (1)
= (600+55)+(200+25)+20+130-30 (1½)
=Rs. 1000 crores (½)
Expenditure Method
National Income = vi+i+xii+xiv-v+ii-x (1)
= 800+100+110+70-60+10-30 (1½)
= Rs. 1000 Crores (½)
GNDI = iv+ii+vi-ix (1)
= 1000 +100 + 50 -(-20) (1½)
= Rs. 1170 (½)
Personal Income = (iv-xi) + (vii-ix+x)-viii-iii (1)
= 1000-80+70-(-20)+30- 40- 90 (1½)
= Rs. 910 Crores. (½)
