Ravi saves 20% of his monthly income. The next year his income goes up by 25% while his expenditure goes up by 30%. His monthly saving increases by what percent?

Question

Accepted Answer

5. Take the income as 100: expenditure 80, saving 20. New income = 125, new expenditure = 80 × 1.30 = 104, so the new saving = 125 − 104 = 21. Increase = 1/20 = 5%.
