Explanation: Concept used Income = Expenditure + savings Calculation Let Rumi's income be 100x Her savings = 100x × 20/100 = 20x New income = 100x × 130/100 = 130x New expenditure = 80x × 140/100 = 112x New savings = 130x - 112x = 18x Income decrement = 20x - 18x = 2x 2x → 750 100x → 750 × 50 = 37500 The answer is 37500.
