12 men in 36 days can do a work.

1 man in a day can do 112×36 work.

8 men in 20 days can do 8×2012×36=1027 work.

Similarly, we find that 20 women in 20 days can do 1027work.

Remaining work =727
Now, because in 60 days a work is done by 20 women.

In 1 day a work done by 20×60 women.

In 4 days 727 work is done by 20×60×727×4= 70 women.
