Explanation:

Let the initially income of Sonu be Rs.100.
saving = 15%
Expenditure = 100 - 15 = 85%
Saving = 100 -85 = Rs.15
Expenditure = 85% of 100 = Rs.85
Income after increment = 100x120/100 = Rs.120
Saving = 15
Expenditure = 120 - 15 = 105
Increment in expenditure = 105 - 85 = Rs.20
Percentage Increment in expenditure = 20/85 x 100 = 23.52%
