Question
A leak in the bottom of the tank can empty the full tank
in 18 hours. An inlet pipe fills water at the rate of 12 liters a minutes. When the tank is full, the inlet is opened and due to the leak the tank is empty in 24 hours. The capacity of the tank is?Solution
Work done by Inlet in 1 hour = 1/18- 1/24 = 1/72 Work done by Inlet in 1 minute = 1/72 × 1/60 =1/4320 Volume of 1/4320 part = 12 litres Volume of the tank = 12 × 4320 = 51840 litres.
