As per question:
20W = 16 days and 16M = 15 days.
So W = 16/20 and M = 15/16.
So M/W = 15/20 = 3/4.
So ratio is 4:3.
20W = 16 days and 16M = 15 days.
So W = 16/20 and M = 15/16.
So M/W = 15/20 = 3/4.
So ratio is 4:3.

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

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

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
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.

20w can take 16 days.
If 16w-----can take 20 days,
16m can take 15 days(given).
so 20:15.
4:3.
