A person can save only 6% of his income. Two years later his income is increased by 15% and he still saves the same amount. what is the increase percent in his expenditure?
Hi Simran,
Let the income of the person be Rs.100
Savings of the person = 6%
So, 6% of 100 = Rs. 6
Expenditure of the person = Total Income - Total Savings
=> 100 - 6 = Rs.94
Two years later the income of the person is increased by 15%
Now, Total Income = 100 + 15% = Rs. 115
As the savings of the person is still the same amount that is Rs. 6
So, the current expenditure of the person = Rs. 115 - 6 = Rs. 109
Total increase in Expenditure = Rs. 115 - 94 = Rs.15
=> Increase % = (15 / 94) X 100
=> 15.95 % is the increase percent in the person's expenditure.
