Validate

Solution:

(b) Since, a man can do a work in 20 days.
Then, 5 men can do it in 4 days.
So, in 2 days of work = 50% work is completed.
Now, a woman can complete the work in 30 days
But here,

1/2

of the work is to be completed.
Again, 1 woman can complete in 30 days.
Then, 30 women can complete the work in 1 day.
So, to complete

1/2

of the work
∴ Required women =

1/2

x 30 = 15
