Question 4:

A tank is filled in 6 hours by three pipes A, B and C. The pipe C is $\frac{3}{2}$ times as fast as B and B is 3 times as fast as A. If pipe A is outlet pipe and B and C are inlet pipe then how many hours will pipe A alone take to empty a full cistern?

Question 9:

A and B two pipes can fill a tank in 24 hours and 48 hours, respectively. If both pipes are opened simultaneously, how much time will it take to fill the tank?

Question 10:

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?
