ATQ, Ratio of investment of X and Y = 20000:50000 = 2:5 Let, total profit at the end of the year = Rs.100a X share = {100a × 0.1 + 0.9 × 100a × 2/(5 + 2)} = (10a + 180a/7) = Rs. (250a/7) Yshare = {5/(2 + 7)} × 0.9 × 100a = Rs. (450a/7) According to the question, (450a/7) – (250a/7) = 2200 Or, 200a/7 = 2200 Or, a = (2200/200) × 7 Or, a = 77 Or, 100a = 7700 Therefore, total profit received = Rs.7700
