Question

    Sohan completes half the work done by Ramesh in 3/4 of

    the time. If they together can complete the work in 20 days, how much time will Ramesh take to complete the work?
    A 11 days Correct Answer Incorrect Answer
    B 23 days Correct Answer Incorrect Answer
    C 30 days Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    ATQ,
    Let time taken by Ramesh to complete the work = t days

    Sohan takes 2 × (3t/4) = 6t/4 = 3t/2 days.

    Efficiency of Ramesh = 1/t,

    Efficiency of Sohan = 2/3t.

    Total efficiency = 1/t + 2/3t = 1/20 Image
    Solving for t, we get t = 30 days.
