In this question, you have to find no. of men equal to women or vice versa first.
Here,
8 men = 12 women
Then 2men = 3 women
Now,
Applying Unitary method, you can get
2 men + 2 women = 3 women + 2 women = 5 women .
i.e. Work done by 5 women is in 48 days.

how can 5 women can do it in 48 days
can u explain
Since 12 women can do a work in 20 days. So, 1 woman will do it in 20*12 days. Therefore, 5 women will do that work in 20*12/5 days i.e. 48 days.
This method is called Unitary method.
