    Question

    A can complete a task in 24 days, B can complete the

    same task in 18 days, and C can complete it in 12 days. A and B work together for 4 days, and then C takes over. How many days will C take to complete the remaining work?
    A 7.33 days Correct Answer Incorrect Answer
    B 8.2 days Correct Answer Incorrect Answer
    C 10.4 days Correct Answer Incorrect Answer
    D 5 days Correct Answer Incorrect Answer

    Solution

    Work done by A and B together in 4 days = 4 Ă— (1/24 + 1/18) = 4 Ă— (7/72) = 28/72 = 7/18. Remaining work = 1 - 7/18 = 11/18. C can complete 1/12 of the work per day. Time taken by C to complete 11/18 of the work = (11/18) / (1/12) = 11/18 Ă— 12 = 22/3 = 7.33 days.
