    A and B together can complete a piece of work in 8 days. B alone can complete the work in 40 days. In how many days can A alone complete the same work?

    A)  8 days

    B)  10 days

    C)  12 days           

    D)  18 days

    Correct Answer: B

    Solution :

     Efficiency of (A + B) = \[\frac{1}{8}\] Efficiency of B = \[\frac{1}{40}\] Efficiency of A = \[\frac{1}{8}=\frac{1}{40}\] \[=\frac{5-1}{40}=\frac{4}{40}=\frac{1}{10}\] So, A complete whole work in = [10 days]
