Question

Please solve the above question..( Quadratic equation).​

Answer 1

Answer:

Let one pipe fills the cistern in x mins.

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

Time 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

Part 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)
