Paulson spends 75% of his income. His income is increased by 20% and he increased his expenditure by 10%. Find the percentage increase in his savings .

Answer»

Let the original income=Rs.100 .

Then , expenditure=Rs.75 and savings =Rs.25

New income =Rs.120 , New expenditure = Rs.((110/100)*75)=Rs.165/2

New savings = Rs.(120-(165/2)) = Rs.75/2

Increase in savings = Rs.((75/2)-25)=Rs.25/2

Increase %= ((25/2)*(1/25)*100)% = 50%
