Question

Pipe A can fill a tank in 3 h. But there is a leakage also, due to which it takes
3.5 h for the tank to be filled. How much time will the leakage take in emptying
the tank if the tank is filled initially?​

Answer 1

Step-by-step explanation:

Part of tank filled by pipe A in 1hr = 13

and let the part of tank supplied by another pipe 1 in 1 hr = 1x

Now, according to question-

13−1x=13.5

1x=13−13.5

1x=13−1035

1x=35−3035×3

x = 21hr

Hence leakage will take 21 hr to empty the tank
