    Answer: (2) 6 days
    Let the A can finish a piece of work = X days, B can finish the same work = X/2 days
    And C can finish same piece of work = X/3 days.

    A, B & C can together work in a day = (1/X + 2/X + 3/X) = 1/2
    6/X = 1/2
    X = 12
    Then, B can work complete = 12/2 = 6 days.
    Hence the answer is (2) 6 days.
