Q6. State the relation between marginal revenue and average revenue.
Ans: 
When MR < AR, AR falls
When MR = AR, AR is constant

good X and less of good Y till MRS falls enough to be equal to the market price and the consumer is in equilibrium.
b. Unless MRS declines continuously as more and more of X is consumed. It will not be equal to  CBSE Sample Question paper - 03 Economics, Class 12 | Sample Papers for Class 12 Commerce and consumer will not reach equilibrium again.

Q21. An economy is in equilibrium. Calculate the investment expenditure from the following:
National income = 800
Marginal propensity to save = 0.3
Autonomous consumption = 100
Ans: 
Y = C + MPC (Y) + I
800 = 100 + (1 - 0.3) 800 + I
I = 800 - 100 - 560
I = 140

Q22. What is 'deficient demand'? Explain the role of 'Bank Rate' in removing it.
Ans: 
Deficient demand: Is the amount by which the aggregate demand falls short of aggregate supply at full employment level. It causes fall in price level.
Bank Rate is the rate of interest at which central bank lends to commercial banks for long term. The central bank lowers bank rate to reduce defilement demand. When central
bank lowers. Bank rate commercial banks also lower their lending rates. Since burrowing becomes cheaper, people burrow more. This leads to raise in aggregate
demand and thus helps in reducing deficient demand.
OR
What is excess demand? Explain the role of 'Reverse Repo Rate' in removing it.
Ans: 
Excess demand is the amount by which the aggregate demand exceeds aggregate supply at full employment level. It causes inflation. Reverse Repo Rate is the rate of interest paid by the central bank on deposits by commercial banks. Central Bank can reduce excess demand by raising the reverse reporate.
When the rate is raised, it encourages the commercial banks to park their funds with the central bank. This reduces lending capacity of the commercial banks. Lending
by the commercial banks to public declines leading to fall in aggregate demand.

Q23. Explain how the government can use the budgetary policy in reducing inequalities in income?
Ans: 
Government can reduce in equalities through its tax and expenditure policy. Government can charge higher rate of tax from higher income groups by imposing higher rate of income tax and higher rate on goods and services purchased by the rich. The money so collected can be spent on the poor in the form of free education, free medical facilities, cheaper housing etc. in order to raise their disposable income.

Q24. Calculate a. GDP and b. factor income to abroad from following data:

 

(^ crore)

i. Compensation of employees

800

ii. Profit

200

iii. Dividends

50

iv. Gross national product at market price

1400

v. Rent

150

vi. Interest

100

vii. Gross Domestic fixed capital formation

200

viii. Net domestic capital formation

200

ix. Change in stock

50

x. Factor income from abroad

60

xi. Net indirect taxes

120

Ans:
 
a. GDPFC = (i) + (ii) + (v) + (vi) + [(vii) + ix) - viii]
= 800 + 200 + 150 +100 + [(200 + 50) - 200]
GDPFC =rs 1300 cr [ Dep = GDCF - NDCF]
b. Factor income to abroad
GNPMP = GDPFC + NIT + NFIA
1400 = 1300 + 120 + FIFA - FITA
1400 = 1300 + 120 + 60 - FITA
FITA =rs 80 crore
