A tank of 3600 cum capacity is being filled with water. The delivery of the pump discharging the tank is 20% more than the delivery of the pump filling the same tank. As a result, twelve minutes more time is needed to fill the tank than to discharge it. Determine the delivery of the pump discharging the tank.

A tank of 4800m^(3) capacity is full of water. The discharging capacity of the pump is 10m^(3) /min higher than its filling capacity. As a result the pump needs 16 min less to discharge the fuel than to fill up the tank. Find the filling capacity of the pump.

Two pipes A and B are opened together to fill a tank . Both the pipes fill the tank in time t . If A separately takes 4 min more time than t to fill the tank B takes 64 min more time than t to fill the tank , find the value of t .

Pipes A and B together can fill an empty tank in 6 2/3 minutes. If A takes 3 minutes more than B to fill the tank, then the time (in minutes) in which A alone would fill one-third part of the tank is:

Capacity of tap B is 80% more than that of A.If both the taps are opened simultaneously, they take 45 h to fill the tank. How long will B take to fill the tank alone?

If tap A can fill a tank 3 times faster than tap B and takes 28 min less than tap B to fill the tank. If both the taps are opened simultaneously, then find the time taken to fill the tank.

Pipes A and B can together fill a tank in 20 hours and pipe C can empty 40% of the tank in 20 hours. Find the time taken by all the 3 pipes together to fill 60% of the tank.

A tank fills completely in 2 hours if both the taps are open. If only one of the taps is open at the given time, the smaller tap takes 3 hours more than the larger one to fill the tank. How much times does each tap take to fill the tank completely?

A pump can be used to either fill or drain a tank.The capacity of the tank is 3600m^(3). The draining capacity of the pump 10(m^(3))/( min higher ) than its filling capacity.What is the draining capacity of the pump if it takes 12 minutes more to fill the tank than to drain it?

The water for a factory is stored in a hemispherical tank whose internal diameter is 14 m. The tank contains 50 kL of water. Water is pumped into the tank to fill to its capacity. Calculate the volume of water pumped into the tank.
