Twenty women can do a work in sixteen days .16 men can complete the same work in 15 days. What is the ratio between the capacity of a man and a woman?

Answer:

Explanation:

$(20\times 16)$ women can complete the work in 1 day.

1 woman 1 day work $=\frac{1}{320}$.

$(16\times 15)$ men can complete the work in 1 day.

1 man 1 day work $=\frac{1}{240}$.

Required ratio $=\frac{1}{240}:\frac{1}{320}$ = 4 : 3
