    Question

    P and Q started a business by investing Rs.8000 and

    Rs.6400 respectively. After 4 months, Q increased his investment by a certain percentage such that at the end of 1 year, the profit shares of P and Q were equal. By how much percentage did Q increased his investment?
    A 18% Correct Answer Incorrect Answer
    B 15% Correct Answer Incorrect Answer
    C 10% Correct Answer Incorrect Answer
    D 12.5% Correct Answer Incorrect Answer

    Solution

    Let the increased investment amount of Q = Rs.x Ratio of profit shares of P and Q = (8000 x 12) : (6400 x 4 + 8y) = 1:1 So, 96000 = 38400 + 8x => x = 7200 Increase in investment of Q = 7200 – 6400 = Rs.800 Required % = (800/6400) x 100 = 12.5%
