Answer 2

Answer:

50 minutes taken to completely filled the tank.

Step-by-step explanation:

Given : There are two pipes an inlet pipe which completely fills a tank at 6 litre/min and an outlet pipe which empties the tank at 4 litre/min. The pipes function alternately for 1 minute and the inlet pipe is the first to function. Considering the capacity of the tank as 50 litres.

To find : How much time will it take to completely fill the tank?​

Solution :

The capacity of reservoir is 50 litres.

For 1st minute inlet pipe opened = 6 liter filled

2nd minute inlet pipe closed, outlet pipe opened = 4 liter emptied.

In 2 minutes the tank filled is 2 liter.

In 1 minute the tank is filled 1 liter.

For 50 liter the tank is filled in 50 minutes as inlet pipe is opened and reservoir is filled.
