In an economy, level of income is₹ 2000 crore and MPC= 0.75. Calculate total income if investment is increased by ₹ 200 crore.

Answer»

Solution :`""K= (1)/(1-MPC)= (100)/(25)= 4`
`""K=4`
`""K= (Delta Y)/(Delta I) ""or ""4 = (Delta Y )/(200)`
`""K= (DeltY )/(Delta I)""or ""4= (Delta y )/(200)`
`""Delta Y= ₹ 800` CRORE
`therefore ""` TOTAL income = `Y+Delta Y= 2000+800= ₹ 2800` crores
