Two pipes running together can fill a cistern in minutes. If one pipe takes 3 minutes more than the other to fill it, find the time in which each pipe would fill the cistern.

Let one pipe fills the cistern in mins.

Therefore, the other pipe will fill the cistern in mins.

Time taken by both, running together, to fill the cistern

Part filled by one pipe in

Part filled by the other pipe in

Part filled by both pipes, running together, in

Thus, one pipe will take 5 mins and other will take mins to fill the cistern.
