    Question

    A and B started a business with investments in the ratio

    4:5 respectively. After 6 months, C joined them with an investment 44% more than the investment of B. Find the profit share of C out of the total profit of Rs 12960 at the end of two years
    A Rs. 1960 Correct Answer Incorrect Answer
    B Rs. 4320 Correct Answer Incorrect Answer
    C Rs. 3920 Correct Answer Incorrect Answer
    D Rs. 1560 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the investments of A and B be Rs. 4x and Rs. 5x respectively.  So, the investment of C = 1.44 × 5x = Rs.7.2x So, the ratio of their investments = (4x × 24): (5x × 24): (7.2x × 18) = 8:10:9 So, the profit share of C = 9/27 × 12960 = Rs. 4320
