    A and B started a business with investments in the ratio

    3:5 respectively. After 5 months, C joined them with an investment 60% more than the investment of B. Find the profit share of A out of the total profit of Rs 3440 at the end of two years.
    A 610 Correct Answer Incorrect Answer
    B 480 Correct Answer Incorrect Answer
    C 720 Correct Answer Incorrect Answer
    D 935 Correct Answer Incorrect Answer

    Solution

    Let the investments of A and B be Rs. 3x and Rs. 5x respectively.  So, the investment of C = 1.60 × 5x = Rs. 8 x So, the ratio of their investments = (3x × 24): (5x × 24): (8x × 19) = 9:15:19 So, the profit share of A = 9/43 × 3440 = Rs. 720
