In an economy, every time the income rises, 75 percent of the rise in income is spent on consumption. Now suppose in the same economy investment rises by Rs. 750 crore. Calculate : (i) change in income, (ii) change in saving.

Answer»

SOLUTION :(i) `MPC=0.75, :. MPS=0.25`
`:. K=1/(1-MPC)=1/(1-0.75)=4`
`:. DeltaY=K. Delta I=4xx750` CRORE = Rs. `3,000` crore
`133`
(II) `DeltaS=DeltaY-DeltaC=3,000-(0.75xx3,000)`
`=3000-2250` crore = Rs. `750` crore.
