Rahul's initial monthly expenditure and savings were in the ratio 5 : 3. His monthly income then rose by 25%. If his initial savings were Rs. 4,500, what is his new monthly income after the increment?

1. 16000
2. 15000
3. 9375
4. 12000

Correct answer: 15000

Solution

Ratio expenditure:savings = 5:3. Initial savings = 4500, so initial expenditure = (5/3) x 4500 = 7500. Initial income = 7500 + 4500 = 12000. After 25% increase: new income = 12000 x 1.25 = 15000.
