Question

A pump can fill a tank with water in 2 hours. Because of a leak, it took 7/3 hrs to fill the tank. The leak can drain all the water of the tank in?

Answer 1

Answer:

Step-by-step explanation:

Let the leak can drain all the water of the tank in y hours

Part of the tank filled by the pipe in 1 hr = 1/2

Part of the tank emptied by the leak in 1 hr = 1/y

1/2−1/y=3/8

⇒1/y=1/2−3/8=1/8

⇒y=8

i.e., the leak can drain all the water of the tank in 8 hours
