REHAMAN  (9 years ago)

his actual income is 100%
he save 25% and he spent 75%
his income incresed by 20%
that mean his income rise to 120%(100 + 20%(100) = 120)
new exp=75+15%(75)=86.25
new save=120-86.25=8.75
% increase in savings = (8.75/25)*100=35%

Let income = Rs. 100 .-. Expenditure = Rs. 75 Saving = Rs. 25

New income = Rs. 120 .-. Expenditure = (115/100) X 75 = 345/4

Saving = 120 - (345/4) = 135/4

Increase % in saving = (35/4) X (1/25) X 100 = 35%
