Let the income of Sonu be Rs. 100

Savings of Sonu = 100 × (15/100) = Rs. 15

Expenditure of Sonu = 100 – 15 = Rs. 85

New income of Sonu = 100 × (120/100) = Rs. 120

If savings amount same, then new expenditure = 120 – 15 = 105

Her expenditure increased by = 105 – 85 = 20

Her expenditure increased by = 20/85 × 100 ≈ 23.5%
