## Pipes and Cisterns – Quantitative Aptitude

**Basic Concepts:**

A pipe is used to fill or empty the tank or cistern.

A pipe used to fill the tank or cistern is known as Inlet Pipe.__Inlet Pipe__:A pipe used to empty the tank or cistern is known as Outlet Pipe.__Outlet Pipe__:- If an inlet pipe can fill the tank in x hours, then the part filled in 1 hour = 1/x
- If an outlet pipe can empty the tank in y hours, then the part of the tank emptied in 1 hour = 1/y
- If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours ( where y > x), then on opening both the pipes, the net part filled in 1 hours = ( 1 / x – 1 / y ).
- If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours ( where x > y), then on opening both the pipes, the net part emptied in 1 hours = ( 1 / y – 1 / x ).
- Suppose that pipe ‘A’ fills the tank as fast as the other pipe ‘B’. If pipe ‘B’ (slower) & pipe ‘A’ (faster) take ‘x’ min & ‘x/n’ min respectively to fill up an empty tank together, then part of the tank filled in 1 hour = (n+1)/x
