    Answer: (3) 7 days
    Explanation:-

    10 women can complete a work = 7 days
    1 women can work in  a day = 1/7 x 10 = 1/70

    10 children can complete a work = 14 days
    1 child can work in a day = 1/10 x 14 = 1/140

    5 women and 10 children can complete work = 5/70 + 10/140
    = (10 + 10)/140
    = 20/140
    = 1/7

    Hence, 5 women and 10 children can complete the work in 7 days.
