A man spends 75% of his income. His income increases by 20% and he increased his expenditure by 15%. His saving are then increased by :

a. 33%
b. 33(1 / 3)%
c. 35%
d. 40%

• 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%
  option c is currect

• 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%
