    Solution

    ATQ, Let the incomes of ‘L’, ‘M’, and ‘N’ be Rs. l, Rs. m, and Rs. n. According to the question, 0.1l : 0.15m : 0.4n = 2 : 3 : 10 Or, l : m : n = (2/0.1) : (3/0.15) : (10/0.4) = 20 : 20 : 25 Sum of the ratios = 20 + 20 + 25 = 65 Therefore, income of ‘L’ = 27000 × (20/65) = Rs. 8308 Income of ‘M’ = 27000 × (20/65) = Rs. 8308 Income of ‘N’ = 27000 - (8308 + 8308) = Rs. 10384 Required sum = (0.9 × 8308) + (0.85 × 8308) + (0.6 × 10384) = 7477 + 7062 + 6230 = Rs. 20769
