Answer and explanation

Correct answer D

Required increase in income is ΔY=800−500=Rs. 300 crores\Delta Y = 800 - 500 = \text{Rs. } 300\text{ crores}. With MPC=0.75MPC = 0.75, the multiplier is k=11−0.75=4k = \frac{1}{1 - 0.75} = 4. Thus, required increase in investment is ΔI=ΔYk=3004=Rs. 75 crores\Delta I = \frac{\Delta Y}{k} = \frac{300}{4} = \text{Rs. } 75\text{ crores}.
