Calculate AD, AS for every level of income and the equilibrium level, from the following schedule: (assuming that the investment is fixed at 40 crores)

In an economy , the investment expenditure is Rs. 70 crores and consumption functin is C= 60 + 0.80 Y . ("i) Determine the equilibrium level of income , (ii) Find the equilibrium income when planned investment expenditure is creased by Rs. 10 crores , (iii) Value of multiplier due to increase in investment expenditure.

On the basis of the following schedule spot the equilibrium level of output:

Suppose investment in the economy is fixed at Rs.40 crores. The consumption expenditure, at different levels of income , is given in the following schedule: {:("Income"(Rs."crores"),200,300,400,500,600,700),("Consumption"(Rs."crose"),220,300,380,460,540,620):} On the basis of the given schedule, answer the following questions: (i) Calculate AD and AS all level of income. (ii) At what level of income will the economy be at equilibrium? (iii)State the level if income where total saving is negative. (iv) Are saving and investment equal at the equilibrium level of income? (v) Calculate MPC and MPS ,when the incme increases from Rs. 400 crores to Rs. 500 crores. (vi) What will be the income level of Rs. 300 crores?

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 .
