Inlet X is 5 times faster than the outlet Y. If Y can empty a cistern in 36 minutes, the find the time when the cistern will be full if both fill pipes are opened together

Pipe X and Y can fill a tank in 10 minutes and 20 minutes respectively. If both the pipes are opened simultaneously, then the time taken to fill the tank is how much?

There are 3 inlet pipes. The first 2 pipes working simultaneously can fill a pool in the same time as the third pipe alone, while the second pipe alone fills the pool 5 hours faster than the first and 4 hours slower than the third. In what time will second and third pipe working together fill the empty pool?

Pipe X, Y and Z can fill a tank in 10 minutes, 5 minutes and 10 minutes respectively. Find the time taken by the tank to be filled, if all the pipes are opened simultaneously.3 minutes19 minutes3.7 minutes2.5 minutesNone

A tank of capacity 25 litres has an inlet and an outlet tap. If both are opened simultaneously, the tank is filled in 5 minutes. But if the outlet flow rate is doubled and taps are opened, the tank never gets filled up. Which of the following can be the outlet flow rate in liters/min?

Three filling pipes, R, S and T, together, can fill an empty tank in two hours. S can fill the tank four times as fast as T. Initially, R alone is opened and after exactly x hours, it is closed and immediately S and T are opened together. The tank is full after exactly another y hours. If the tank was filled in a total of 4 hours, and x ≠ y, find the time (in hours) that T alone would take to fill the tank.6201224
