On a Jaipur rooftop, a tap fills an empty water tank in 9 hours, but a crack at the bottom can drain the full tank in 36 hours. If the tap runs and the crack keeps leaking, in how many hours will the tank fill?

Question

Accepted Answer

12. Net rate = 1/9 − 1/36 = 3/36 = 1/12 of the tank per hour, so the tank fills in 12 hours.
