A tank has two pipes. The first pipe can fill it in 5 hours and second can empty it in 20 hours. If two pipes be opened together at a time then the tank will be filled in -

A, B and C are three pipes connected to a tank. A and B together fill the tank in 6hrs. B and C together fill the tank in 10 hrs. A and C together fill the tank in 7.5 hours. In how much time will A alone fill the tank?

There are two inlet pipes $\mathrm{A}$ and $\mathrm{B}$ can fill a tank in 20 minutes and 30 minutes respectively. Outlet pipe C can empty the whole tank in 15 minutes. What time will they take (in minutes) to fill the whole tank, if they start together?

Pipe $A$ and $B$ running together can fill the cistern in 6hours. A takes 5 hours more than B to fill the cistern when opened separately. In how much time pipe B can fill the cistern alone?

Two pipes A and B can separately fill the tank in 4 hours and 8 hours respectively. If both the pipes are opened simultaneously in empty tank, then the tank will be filled in.

Pipe A alone can fill a tank in 8 hours. Pipe B alone can fill it in 6 hours. If both the pipes are opened and after 2 hours Pipe A is closed, then the other pipe will fill the tank in ?

A pipe can fill a cistern in 12 minutes and another pipe can fill it in 15 minutes, but a third pipe can empty it in 6 minutes. The first two pipes are kept open for 5 minutes in the beginning and then the third pipe is also opened. Number of minutes taken to empty the cistern is:

Pipes A and B can fill a tank in 10 hours and 13$\frac{1}{3}$ hours, respectively. Pipe C is an emptying pipe. When all the three pipes are opened together, the tank is filled in 8 hours. In how many hours will Pipe C alone empty 25% of the tank?

Two pipe A and B can fill a cistern in 10 and 15 hours respectively. If both the pipes are opened for one-one hour alternatively starting from pipe A, then find the total time required to fill the cistern completely?
