Question
The income of a person is Rs.12000 and his expenditure
is Rs.8000. In the next year his income and expenditure is increased by 10% and 20% respectively. His saving is what percent less than that of the previous saving?Solution
Initial Savings = 12000 – 8000 = Rs. 4000 Next year, Income = 12000 × (110/100) = Rs.13200 Expenditure = 8000 × (120/100) = Rs.9600 Saving = 13200 – 9600 = Rs.3600 Required % = [(4000 – 3600)/4000] × 100 = 10%
