    Answer: (1) 16/3 days

    Explanation:-
    Let a man can work in a day = X  and A woman can work in a day = Y.
    4 men and 6 women complete a work in 8 days,
    Then, 4 X + 6 Y  = 1/8 …………………………. (1)
    2 men and 9 women also complete in 8 days,
    2 X + 9 Y = 1/8          ………………………… (2)
    Solve equation (1) & (2),
    Then,  X = 1/64  &  Y = 1/96

    Therefore, 1 woman can do a work in a day = 1/96
    Then,  18 women can do in a day = 18/96
    = 3/16

    There are 18 women can complete the work in 16/3 days.

    Hence, the answer is (1) 16/3 days.
