Answer 1

Answer:

D. 10%

A woman's expenditure and savings are in the ratio 5 : 3. Let expense = 500 , savings = 300 and income = 800 new income = 800 + 15% of 800 = 800 +120 = 920 new expense = 500+ 18% of 500 = 500 + 90 = 590 new savings = 920 – 590 = 330 Percentage increase in savings = [(330 – 300 )/300] × 100 = 30/300 × 100% = 10%
