Question
The income of a person is Rs.15000 and his expenditure
is Rs.12000. In the next year his income and expenditure is increased by 8% and 13% respectively. His saving is what percent less than that of the previous saving?Solution
Initial Savings = 15000 – 12000 = Rs. 3000 Next year, Income = 15000 × (108/100) = Rs.16200 Expenditure = 12000 × (113/100) = Rs.13560 Saving = 16200 – 13560 = Rs.2640 Required % = [(3000 – 2640)/3000] × 100 = 12%
