    Answer:

    6 days

    Step-by-step explanation:

    Work done by A in 1 day = 1/10

    Work done by B in 1 day = 1/15

    Work done by A and B together in 1 day = 1/10 + 1/15 = 5/30 = 1/6

    Therefore, A and B will complete the work together in [ 1 ÷ (1/6) ] days = 6 days

    Answer:

    A can do a piece of work in 10 days.

    A can do 1/10 part of a piece of work in 1 day.

    B can do a piece of work in 15 days.

    B can do 1/15 part of a piece of work in 1 day.

    A and B together can do (1/10 + 1/15)  part of a piece of work in 1 day

    = 1/6

    A and B together can do a piece of work in 1/1/6 days

    = 6 days

    therefore,  A and B will get 6 days to do the work
