    Question

    A and B together can complete a piece of work in 35 days

    while A alone can complete 50% of the work in 20 days. Find the time taken by B to complete 12.5% of the work.
    A 30 days Correct Answer Incorrect Answer
    B 36 days Correct Answer Incorrect Answer
    C 32 days Correct Answer Incorrect Answer
    D 35 days Correct Answer Incorrect Answer

    Solution

    Time taken by A to complete the whole work = 20/0.50 = 40 days Let total work = 280 units Amount of work done by A and B together in one day = 280/35 = 8 units Amount of work done by A alone in one day = 280/40 = 7 units Amount of work done by B in one day = 8 – 7 = 1 units Desired time = 0.125 × 280/1 = 35 days
