    Answer: (a) 40 days

    Solution:-
    Let 1 man’s 1 day work = x
    and 1 woman’s 1 days work = y.
    Then, 4x + 6y = 1/8
    and 3x+7y = 1/10
    solving, we get y = 1/400     [means work done by a woman in 1 day]

    10 women 1 day work = 10/400 = 1/40

    Then, 10 women will finish the work in 40 days

    Hence, the correct answer is option (a) 40 days.
