3)	16 days	4)	25 days
5)	None of these

Answer : 15 days

. Let Ramesh can finish a work x days.

So, Bipin can finish the same work in 3x days.

According to equation (3x - x) = 40 days

or x = 20 days.

So, Ramesh can do the work in 20 days and Bipin can do the same work in 3 20 = 60 days.

If they work together day will be taken by them = (20 x 60) /(20+60) = 15days
