SSC CHSL 2023 PYQ — Question 56

The correct answer is option 2 i.e. 29$\frac{12}{17}$%.

Let A's income = 100

Expenditure = 68

Savings = 100 - 68 = 32

New income = 125

Savings = 32 × (115/100) = 36.80

Expenditure = 125 - 36.80 = 88.20

Increase in expenditure = 88.20 - 68 = 20.20

Required percentage = (20.2/68) × 100 = $29\frac{12}{17}\%$

Therefore, the percentage increase in his monthly expenditure will be $29\frac{12}{17}\%$.
