Hii,
We have to take the following steps to calculate the increase percent in his expenditure.
Let the persons income be 600.
Saving =6% of income
Income = 600, Saving = 36 Expenditure = 564
Now, increment by 15% = 600*15/100 = 90
Therefore new salary = 600+90 = 690
Saving = 36 and expenditure = 654
Increment in expenditure = 654-564 =90
% increase in expenditure = 90/564 * 100 = 15.95% i.e. approx. 16%.
Hope this helps.
