Work done by the women
20 women -->16 day
1 women ----16/20
One day work of 1 women 20/16
Work done by a man
16 man ---->15
1 man ------>15/16
one day work of 1 man 16/15
(1-day work of one man) : (1-day work of one woman)
(20/16) / (15/16)
20/15 = 4/3 i.e 4:3.
20 women -->16 day

@Karthik.
Because in question they asked men : women that's why we can't take women : men.

Why we don't take women as first.
3 (women) : 4 (men).
Can anyone explain me?

Ratio of man and woman is asked here, but not woman and man. So the answer will be 3:4 (option A).

=> 20women, 15men,
=> 20:15,
=> 20/15=4/3,
=> 4:3.
=> 20:15,
=> 20/15=4/3,
=> 4:3.

We can easily find out the answer for this question by reverse thinking.
Take an option A.
Divide 16 by 3 it can't. We can't Divide it exactly. So it is not an answer.
Take option B.
Divide 16 by 4 and 15 by 3 hence it is the answer.
