You can put this solution on YOUR website!
The given info tells you there are 21 employees and 1/3 are men.
21+%2A+%281%2F3%29+=+7 so there are 7 men. Thus there are 14 women
You are asked to find out ho wmany women to hire such that men wind up being 1/4 of the total
The number of men won't change.
7+%2A+4+=+28 We need to get a total of 28 employees.
Since there are 21 now, and we need 28, hire 7 women.
Answer A
