## Relation between Investment Multiplier K and MPC

### PRACTICAL QUESTIONS

#### Example 1.

Calculate multiplier if MPC is:

(i) 0.75;

(ii) 0.90.

### Example 3.

In an economy, income generated is four times the increase in investment expenditure. Calculate the values of MPC and MPS.

### Example 16.

In an Investment 75 percent of the increase in income is spent on consumption Investment is increased by Rs 1,000crore. Calculate:(a)total increase in income;(b)total increase in consumption expenditure.

MPC =0.75

Change in Investment = 1000

a) change in income

b) Change in consumption

### Example 17.

An increase of ₹ 250 crores in investment in an economy resulted in total increase in income of ₹ 1,000 crores. Calculate the following:

(a) Marginal propensity to consume (MPC),

(b) Change in Saving,

(c) Change in consumption expenditure,

(d) Value of multiplier.

Change in investment = 250

change in income = 1000

a MPC = ?

b Change in savings = ?

c change in consumption = ?

d K = ?

### Example 18.

In an economy, income increases by 10,000 as a result of a rise in investment expenditure by 1,000 calculate;

(a)Investment Multiplier;

(b)Marginal Propensity to consume.

## Example 19

In an economy, an increase in investment leads to increase in national income which is three times more than the increase in investment. Calculate marginal propensity to consume.
