Question
The income of a person is Rs.13000 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 = 13000 – 8000 = Rs. 5000 Next year, Income = 13000 × (110/100) = Rs.14300 Expenditure = 8000 × (120/100) = Rs.9600 Saving = 14300 – 9600 = Rs.4700 Required % = [(5000 – 4700)/5000] × 100 = 6%
