    Answer: (2) 40
    Explanation:-
    A can do a piece of work = 60 days.
    A can do work in a day = 1/60
    A can do work in 12 days = 12/60
    = 1/5
    Remaining work = 1 – 1/5 = 4/5

    B can do the same  work = 50 days.
    B can do the remaining work = 4 x 50/5 = 40 days.
    The answer is (2) 40.
