B Correct answer
Explanation

Let original income be 100. Expenditure = 65, savings = 35. After 30% increase: new income = 130. After 20% expenditure increase: new expenditure = 65×1.2 = 78. New savings = 130-78 = 52. Percentage change in savings = (52-35)/35 × 100 = 17/35 × 100 = 48.57% ≈ 48.6%. Option B is correct.
