 1 woman's 1 day's work = |
1 | . |
| 320 |
(16 x 15) men can complete the work in 1 day.
| 1 man's 1 day's work = |

Its very simple. See that:
20*16 = 320. work done by women.
16*15 = 240. work done by men.
Ratio = 320/240 = 4/3. Answer.
20*16 = 320. work done by women.
16*15 = 240. work done by men.
Ratio = 320/240 = 4/3. Answer.

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.

Ok what you saying is 100% right Jananipriya. Then why we have to do cross multiple work as they given in last step.

Since the ratio has been asked between man and woman which is 1/240, 1/320 per day respectively. That is it Pavan.

Why we take 1/240:1/320?
Why not 1/320:1/240?
It will give us reverse answer as 3:4 which is the 1st option.
Why not 1/320:1/240?
It will give us reverse answer as 3:4 which is the 1st option.

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

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

Very simple
As per question 20Women*16=16men*15
Men:women=(16*20)/(15*16)=4:3
As per question 20Women*16=16men*15
Men:women=(16*20)/(15*16)=4:3
