    Answer : Option A

    Explanation :

    As per question:

    Work done by A in 1 day: work done by B in 1 day = 2:1

    A and B working together can complete the work in 20 days.

    So, (A+ B)'s one day work = 1
                                              20

    Therefore, A's one day work will be = 1    ∗   2   =   2   =   1
                                                         20        3      60       30

    Therefore, A alone can finish the work in 30 days
