Given that :

C+ 100+ 0.75 Y

Planned Investment = ₹1000 Crores

The equilibrium level of income is :

₹4400 Crores

The correct answer is option (4) : ₹4400 Crores

To find the equilibrium level of income (Y), we need to set planned investment equal to aggregate expenditure (which includes consumption expenditure and investment) in a closed economy where there are no taxes or savings.

Given: Planned Investment (I) = ₹1000 Crores

Consumption function: C = 100 + 0.75Y

At equilibrium, aggregate expenditure (AE) equals income (Y):

AE = C + I

Substituting the values: AE = (100 + 0.75Y) + 1000

Since AE = Y (at equilibrium), Y = (100 + 0.75Y) + 1000

Now, solve for Y:

Y = 100 + 0.75Y + 1000

Y = 1100 + 0.75Y

0.25Y = 1100

Y = 1100 / 0.25

Y = 4400

Therefore, the equilibrium level of income (Y) is ₹4400 Crores.
