Answer:
9men do a job in 1 day.So 1 man does (1/9)th of the job in a day.
12 women do a job in 1 day.
So 1 woman does (1/12)th of the job in a day.
Let the number of women be w to work with 6 men.
(6/9) +(w/12) = 1 or
(24/36) +(3w/36) = 1
24 + 3w = 36, or
3w = 12
So the number of women required = 12/3 = 4 to do the work in 1 day.
