    Solution

    ATQ, Let the incomes of ‘Pawan’, ‘Qureshi’ and ‘Ranjan’ be Rs. ‘5x’, Rs. ‘3x’ and Rs. ‘4x’, respectively Expenditure of ‘Pawan’ = 5x – 5x × 0.4 = Rs. ‘3x’ Expenditure of ‘Qureshi’ = 3x – 3x × 0.2 = Rs. ‘2.4x’ Expenditure of ‘Ranjan’ = 4x – 4x × 0.3 = Rs. ‘2.8x’ ATQ, 3x – 2.4x = 1500 Or, 0.6x = 1500 Or, x = 2500 Average of incomes of ‘Pawan’, ‘Qureshi’ and ‘Ranjan’ = {(5x + 3x + 4x)/3} = Rs. ‘4x’ Or, average of incomes of ‘Pawan’, ‘Qureshi’ and ‘Ranjan’ = 4x = 4 × 2500 = 10000 Or, y = 10000
