ATQ, Let the income and saving of Michael be Rs. '6x' and Rs. '2x', respectively. So, his expenditure = 6x - 2x = Rs. '4x' His new expenditure = 4x + 0.25 × 2x = Rs. '4.5x' Since savings remain the same, therefore His new income = 4.5x + 2x = Rs. '6.5x' ATQ: 6.5x - 6x = 1500 Or, 0.5x = 1500 Or, x = 1500 ÷ 0.5 Or, x = 3000 So, his initial income = 6x = 6 × 3000 = Rs.18000
