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?


A) 3 : 4

B) 4: 3

C) 5 : 3

D) 3 : 5

E) Cannot be Determined

Answer:

Option B

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
