Answer 1

Answer:

Two pipes running together can fill a cistern in$3 \frac{1}{3}$ minutes. If one pipe takes 3 minutes more than the other to fill it,  8 min time is required.

Step-by-step explanation:

Let one pipe fills the cistern in x mins.  

Therefore, the other pipe will fill the cistern in (x+3) mins.  

Time is taken by both, running together, to fill the cistern = 3 1/13 mins = 40/13 mins  

Part filled by one pipe in 1 min = 1/x  

Partly filled by the other pipe in 1 min = 1/(x+3)  

Part filled by both pipes, running together, in 1 min = 1/x + 1/(x+3)
