Question
Two pipes X and Y can fill a cistern in 21 hours and 24
hours, respectively. The pipes are opened simultaneously, and it is found that due to a leakage in the bottom, it takes 48 minutes more to fill the cistern. When the cistern is full, in how much time will the leak empty it if no pipe is open during that time?Solution
