(C) Let the initial income be $₹ 100$.Since he spends $75 \%$ of his income,his initial expenditure is $₹ 75$.Therefore,his initial savings = $	ext{Income} - 	ext{Expenditure} = 100 - 75 = ₹ 25$.Now,his income increases by $20 \%$,so the new income = $100 + (20 \% 	ext{ of } 100) = ₹ 120$.His expenditure increases by $10 \%$,so the new expenditure = $75 + (10 \% 	ext{ of } 75) = 75 + 7.5 = ₹ 82.5$.New savings = $	ext{New Income} - 	ext{New Expenditure} = 120 - 82.5 = ₹ 37.5$.Increase in savings = $	ext{New Savings} - 	ext{Initial Savings} = 37.5 - 25 = ₹ 12.5$.Percentage increase in savings = $(\frac{	ext{Increase in Savings}}{	ext{Initial Savings}}) 	imes 100 = (\frac{12.5}{25}) 	imes 100 = 0.5 	imes 100 = 50 \%$.
