Six Pipes Are Fitted To A Water Tank. Some Of These Are Inlet Pipes And The Others Outlet Pipes. Each Inlet Pipe Can Fill The Tank In 9 Hours And Each Outlet Pipe Can Empty The Tank In 6 Hours. On Opening All The Pipes, An Empty Tank Is Filled In 9 Hours. How Many Inlet Pipes Are There?

Answer»

x / 9 – y / 6 = 1/9;

2X – 3y = 2

We can compute that x = 4 and y = 2.

Thus, Inlet PIPE = x = 4.

x / 9 – y / 6 = 1/9;

2x – 3y = 2

We can compute that x = 4 and y = 2.

Thus, Inlet pipe = x = 4.
