Question

19. A pipe can fill the cistern in 6 hours. But, it is filled
in 8 hours due to leakage. If the tank is now full,
in how many hours will it be empty because of
leakage?​

Answer 1

Answer:

12 hours

Step-by-step explanation:

A pipe can fill a cristern in 1 hours = 1/6

let the leak is emptied the cristern in 1 hours = 1/ t

according to question = 1/6-1/t=1/8

the lcm of 6 and 8 is 24

then,

1/t=8-6/24

1/t=2/24

then,

t=12 hours
