Answer 2

Step-by-step explanation:

For this you must be aware of unitary method

Let me introduce you an example:

Example--

3 boys can complete a work in 1 days

Then,1 boy can complete the same work in 1 × 3 days=3 days

Then,2 boys can complete the same work in = 3/2 days

POINT TO REMEMBER:-

Always calculate work done by 1 man/woman/boy/girl.....

Main solution:--

20 women can complete a work in - 12 days

1 woman can complete the same work in 20 × 12 days = 240 days

3 women can complete the same work in 240/3 days = 80 days

So,time taken by 3 women to complete the work = 80 days
