This Question has 2 answers.
Let the income of Raman be Rs. 100
According to the problem statement
Amount to be spend by Raman can be given as
Amount spent = 100 × (80/100) = Rs. 80
Now the savings is 100 – 80 = Rs. 20
If income increased by 25%, new income will be
New income = 100 × (1 + 25/100) = Rs. 125
Expenditure increased by 10% can be given as
final expenditure = 80 × (1 + 10/100) = 80 × 1.1 = Rs. 88
Savings can be given as 125 – 88 = 37
Increase in saving is 37 – 20 = Rs. 17
percentage increase in savings can be given as = 17 × 100/20 = 85%
The increase in savings is 85%Let the income of Raman be Rs. 100
