Two pipes A and B are opened together to fill a tank. Both pipes fill the tank in a certain time. If A separately takes 16 min more than the time taken by ( A + B ) and B takes 9 min more than the time taken by ( A + B ). Find the time taken by A and B to fill the tank when both the pipes are opened together.

- 10 min
- 12 min
- 15 min
- 8 min
Correct Option: B
Here, a = 16 and = 9
Required time = √ab
√16 x 9 = 4 x 3 = 12 min
