In an economy, the equilibrium level of income falls short by Rs. 500 crores. Calculate the additional investment needed to achieve the equilibrium level of income , if `80%` of increased income is spent on consumption.

in an economy equilibrium level of income is Rs. 12,000 crore , the ratio of MPC t MPS is 3:1 Calculate the additional investment needed to reach a new equilibrium level of income of RS. 20,000 crore .

Calcualte the additional investment needed if the equilibrium level of income falls short by Rs. 1,000 crores . It is given that consumption function is given as: C =120+0.8Y.

in an economy investment is increased by Rs. 300 crore .If MPC is 2/3 , calculate increase in national income .

from the following information about an economy , calculate (i) its equilibrium level of national income and (ii) its savings at equilibrium level of national income and (ii) saving at equilibrium level of national income , consumption function C =200+0.9Y ( where C= consumption experendilture and Y= national income ). investment expenditure I=3,000 .

In an economy, the marginal propensity to consume is 0.8. If investment increases by Rs. 1,000 crores, calculate the total increase in income.
