If MPS = 0.30, Autonomous Consumption = Rs 50 crores and Investment = Rs. 100 crores, then Equilibrium Income will be:
So consumption Function is C = 50+ 0.70 Y where Y in the income in the economy.
At equilibrium level of income,
AS=AD
Y= C+I
=> Y= 50 + 0.70 Y + 100
=> Y - 0.70 Y = 50 + 100
=> 0.30 Y = 150
=> Y = 150/ 0.30 = Rs. 500 crores
