24 Discuss various types of short –run costs
Ans The various short-run costs can be explained with neat diagrams
1) Total fixed cost (TFC): it is a payment made for fixed factors in the short –run. It remains
the same with the change in the level of production(TFC=TC-TVC)
2) Total variable cost (TVC) : it includes payment made to the variable factors of production
.it changes along with the change in output.(TVC=TC-TFC)
3) Total cost (TC): It includes both total fixed cost and total variable cost(TC=TFC+TVC)
4) Average fixed cost (AFC): It is the per unit fixed cost of production of a
commodity(AFC=TFC/Q) or (AFC=AC-AVC)
5) Average variable cost(AVC): It is the cost per unit variable cost of production of a
commodity(AVC=TVC/Q) or (AVC=AC-AFC)
6) Average cost(AC): It is per unit total cost of production (AC=AFC+AVC) or (AC=TC/Q)
7) Marginal cost(MC): It is the addition to the total cost (MC=TCn-TCn-1)
25 Explain elasticity of demand with the neat diagram
Ans There are five types
1) Perfectly elastic demand: In this case a very small change in price leads to an infinite
change in demand(ped=∞)
2) Perfectly in elastic demand : In this case whatever may be the change in price , the
quantity demanded will remain constant(ped=0)
3) More elastic demand : In this case the percentage change of demand is greater percentage
change in price (ped>1)
4) Less elastic demand: In this case the percentage change in demand is less than the
percentage change in price(ped<1)
5) Unitary elastic demand: In this case the percentage change in demand is equal to
percentage change in price(ped=1)

IV. Answer the following questions: - 2 X 10 = 20
29. Explain how a consumer reaches equilibrium using Indifference Curve technique.
Ans. Here we can explain how a consumer attains equilibrium by using.
a) Indifference Curves and b) Budget line.
Assumptions:
1. Income of the consumer is given
2. Consumer is rational
3. Prices of goods and services are constant
4. Consumer is aware of the Indifference Map
5. All goods are homogeneous and divisible
This is clearly explained with the help of a diagram.
In the diagram IC1, IC2, IC3 and IC4 Indifference Curves are drawn. PQ is budget
line. ABCD and E points are combination of X and Y goods Which of the points from
A to E is the optimum choice of a consumer. Is point B optimal? No, because B lies
below the budget line PQ and therefore does not give maximum satisfaction. Are
points C and E optimal? No, because C and E are on the IC curve which gives
minimum satisfaction than the above IC curves. Is point D optimal? No, because B
lies on IC4 which gives maximum satisfaction but it is far above budget line PQ.
Hence, the point A is optimal. The point A lies on IC2 and it touches the budget line
PQ. Here
consumer can purchase the combination with his budget and he attains equilibrium by
getting
maximum satisfaction. This is called optimal choice of a consumer.
30. Explain the functions of RBI.

4. Lender of last resort: When a commercial bank is under financial crises and not able
to get finance from any banks, RBI will provide finance to them.
5. Clearing house: RBI acts as a clearing house by clearing the disparities between
subordinate banks in lending and borrowing.
6. Leader of money market: RBI controls the entire money market in the nation and

V. Answer the following questions: - 2 X 5 = 10
31. If the demand and supply function of raw cotton are Qd = 250 – 50p and Qs = 25 +
25p,
find the equilibrium price and equilibrium quantity demanded and supplied and
prove that
any price other than equilibrium price leads either to excess supply or excess
demand.
Ans: Qd = Qs
250 – 50p = 25 + 25p
-50p -25p = 25 – 250
-75p = -225
P = 225 / 75 = 3
Equilibrium price = 3
When p is 3
Qd = 250 – 50p Qs = 25 + 25p
Qd = 250 – 50 x 3 Qs = 25 + 25 x 3
Qd = 250 – 150 Qs = 25 + 75
Qd = 100 Qs = 100
So at equilibrium price = 3,
Qd = Qs = 100
Suppose if the price = 2 there will be excess of demand
Qd = 250 – 50p Qs = 25 + 25p
Qd = 250 – 50 x 2 Qs = 25 + 25 x 2
Qd = 250 – 100 Qs = 25 + 50
Qd = 150 Qs = 75
Qd> Qs
150 >75
Suppose if the price = 4 there will be excess of supply
Qd = 250 – 50p Qs = 25 + 25p
Qd = 250 – 50 x 4 Qs = 25 + 25 x 4
Qd = 250 – 200 Qs = 25 + 100
Qd = 50 Qs = 125
Qd <Qs
50<125
Thus equilibrium price is 3
32. The market demand curve for commodity and the total cost for monopoly firms
producing the commodity is given by the schedule below:
Quantity(Q) 0 1 2 3 4 5 6 7 8
Price in Rs. (P) 52 44 37 31 26 22 19 16 13
Total costs (Tc) 20 60 85 100 102 105 109 115 125
Use the information to calculate the following:
a. The MR and MC schedules
b. The quantities for which MR and MC are equal
c. The equilibrium quantity of output and equilibrium price of the commodity
Q P TC MC TR (P x Q) MR
0 52 20 20 0 0
1 44 60 40 44 44
2 37 85 25 74 30
3 31 100 15 93 19
4 26 102 02 104 11
Ans:
b) The quantity for which MR = MC is 6
c) Equilibrium output = 6 and equilibrium price = 19

III. Answer the following 5X8=40
21 Explain the movements along the demand curve and shift in demand curve with a neat
diagram
Ans 1) Expansion and contraction: When price is less the demand is more and when
price is more
the demand is less thus anychange in price leads to movements along demand
curve
In the diagram when price decreases from P to P1 the demand expands from Q to Q1
so the
demand curve moves downwards it is called expansion of demand likewise when the
price
increases from P to P2 the demand contracts Q to Q2 so the demand curve upwards it
is called
contraction of demand.
2) Increase and decreasing demand: Other things remaining constant if the income of the
consumer
increases the demand for the goods changes at each price it leads to shift in demand curve
In the diagram the right ward shift of demand curve from DD to D1 D1 is called increase
in demand
likewise if demand curve shift leftward from DD to D2 D2 is called decrease in demand.
22 Mention the factors determining price elasticity of demand
Ans The price elasticity of demand depends several factors some of them are
1) Nature of goods
2) Availability of substitutes
3) Income of the consumer
4) Habits
5) Price of goods
6) Varity of uses
7) Differed consumptions
8) Market awareness
23 Explain with a neat diagram how the long run average cost curve is derived.
Ans All the factors are variable in long run hence there is no total fixed cost or average fixed
cost in long
run . So they are called long run average cost
In the diagram SAC1, SAC2,SAC3,SAC4 and SAC5 is short term average cost curve the
point
PQRST is the minimum point if each SAC . If these minimum points are joined together
is called long run .The point R of SAC3 is least cost combination that is the cost is minimum, the
output is maximum.
24 Explain TR and TC approach under monopoly firm with neat diagram
Ans A monopoly firm attains its equilibrium at point where TR is maximum and TC is
minimum at this
point the firm reaches maximum profit
In The diagram TR and TC is total revenue and total cost respectively .π is the profit curve.
The profit of monopoly firm as given by TR-TC.In the diagram we find BD distance is a
maximum . Thus the firm attains equilibrium with OQ output. The point A and C is called break-
even points where TR=TC(no loss no gain). Before OQ1 and after OQ2 the firm suffers loses
because TC >TR. After OQ1 and before OQ2 the firm is under profit because TR<TC.
25 Mention the important concepts of national income(Macro-economic identities)
Ans The concepts of national income are
1) Gross domestic product (GDP) it is aggregate value of final goods and services produced
within the country during the year GDP=C+I+G+netX
2) Net domestic product(NDP) it is aggregate money value of all final goods and services
produced within the country less depreciation NDP=GDP-Depreciation
3) Gross national product (GNP) it is aggregate money value of all final goods and services
produced by a country in a year including net income from abroad GNP=C+I+G+(X-
M)+(R-P)
4) Net national product (NNP) it includes the value of total output of consumption goods
and investment goods NNP=GNP-depreciation cost
5) Personal income it is that part of the national income of a country which is received by
the people or households
6) Personal disposal income (PDI) the actual income which can be spent on consumption
after deducting direct access is called disposal income (PDI=PI-personal taxes)
26 Explain the new definition of money supply.
Ans At present there exist only three monitory aggregates that is NM1,NM2 and NM3
1) NM1 =currency with the public + demand deposits with the banking system+ other
deposits with RBI
2) NM2= NM1+ Short term time deposits of residents
3) NM3=NM2 + Long term time deposits of residents+ call or term funding from financial
institutions.
27 Explain the consumption functions of Keynes.
Ans. It is the important concept of general theory . It is also called propensity to

In the diagram income is measured along OX axis and consumption is measured along OY axis.
OA curve is in 45 degree . All the points on this curve equal to income and consumption. C is the
consumption curve. At point B C=Y or OY1=OC1 .When income increases to OY2 consumption
increases to OC2 but increase in consumption is not equal increase in income Y1 Y2>C1 C2 the
income saved is S S1

IV. Answer the following 10X2=20
29. Explain the law of variable proportion with the help of a table and diagram.
Law of variable proportion refers to the relationship between the proportion of input and output in
short period.
There are 3 stages in this law. They are –
a. First stage: Increasing returns.
b. Second stage: Diminishing returns
c. Third stage: Negative returns
Assumptions of the law:
1. Technology is constant
2. Some inputs are constants
3. All the units of the variable factors are equally efficient
4. Factors of production are not perfect substitutes
The law can be understood with the help of the following table:
Land
(in
acre)
Amount of capital
(in Rs.)
Units of
labour
Total product
(in tonnes)
Average
product (in
tonnes)
Marginal
product (in
tonnes)
1 10,000 1 5 5 5
1 10,000 2 11 5.5 6
1 10,000 3 18 6 7
1 10,000 4 20 5 2
1 10,000 5 21 4.2 1
1 10,000 6 21 3.5 0
1 10,000 7 20 2.86 -1
First stage: At this stage marginal product increases i.e. total output increases at an increasing rate.
Average product also increases. In this situation law of increasing returns is set to operate.
Second stage: Here the total output continues to increase but at a diminishing rate. This stage continues
till total product reaches the maximum and marginal product becomes zero. The average product goes on
diminishing. But both average product and marginal product remain positive.
Third stage: At this stage total product starts declining and marginal product becomes negative. The
average product also falls.
30. Describe the short run equilibrium under a monopolistic competition.
Ans: A monopolistic firm can achieve equilibrium with the following conditions:
a. MR = MC.
b. MC curve intersects the MR curve from below and moves upwards.
c. Price should be more or equal to AVC
There are 3 short run equilibrium situations in monopolistic competitions.
I. Abnormal profit. MR = MC at point E which shows equilibrium output OQ and equilibrium
price OP. The total revenue of the firm is OPRQ and total average cost is OP1SQ. Thus the
firm profit of P1PRS which is shown in shaded area.
Profit = TR – TC
= OPRQ – OP1SQ
= P1PRS abnormal profit (shown in shaded area)
II. Normal profit. MR = MC at point E which show equilibrium output OQ and equilibrium price
OP. Total revenue of the firm is OPRQ and total cost is OPRQ. Thus the firm is earning Zero
profit (It is also called economic profit)
Profit = TR – TC
= OPRQ – OPRQ
= 0 (normal profit)
III. Losses. MR = MC which shows equilibrium output OQ and equilibrium price OP.Total ravenu
of the firm is OP1RQ and total cost is OPRSQ . Thus firm is under a losses of P1PRS.
Profit = TR – TC
= OPRQ – OP1SQ
= P1PERS (loss)
V. Answer the following 5X2=10
31. Write the process of credit creation by commercial banks with the help of an
example.
Ans: The process of credit creation of banks starts with lending out of primary deposits.
In this process we make the following assumptions.
a. There are A, B, C banks in this process.
b. Each bank has to keep 10% of cash reserve
c. A customer has kept new deposit of Rs. 1000 in bank A.
Bank A receives cash deposit of Rs. 1000 from a customer. Bank keeps Rs. 100
(10%) as reserve and lends Rs. 900 to Mr. X. It is shown in the balance sheet below.
Balance sheet of bank A
Liabilities Assets
Deposits: Rs.1000
Total: Rs.1000
Cash reserve: Rs.100
Loan to Mr.X Rs.900
