If 42 women can do a work in 18 days, how many women will do the same work in 21 days?
Explanation
To find the answer, we calculate the total work:
42 women x 18 days = 756 woman-days
Since the work remains the same, we divide the total work by 21 days:
756 woman-days ÷ 21 days = 36 women
So, 36 women can do the same work in 21 days.
