    Question

    The ratio of time taken by P, Q and R to complete work

    alone is 6:8:3 respectively. If all three together complete the work in 5 days, then find in how many days P alone will complete two-third of the same work?
    A 12.5 days Correct Answer Incorrect Answer
    B 19.5 days Correct Answer Incorrect Answer
    C 14.1 days Correct Answer Incorrect Answer
    D 16 days Correct Answer Incorrect Answer

    Solution

    Ratio of efficiency of P, Q & R = 4 : 3 : 8 So, let total work = (4x + 3x + 8x) × 5 = 75x unit Required days = 75x × 2/3 × 1/4x = 12.5 days
