Question

8. A pipe can fill a cistern in 16 hours. Due to a leakage at the bottom of the cistern, it is filled in 20 hours
When the cistern is full, in how much time will it be emptied by the leakage?

solve the question​

Answer 1

Answer:

Step-by-step explanation:let leakage= B

A's 1 hour work=1/16

(A+B)'s 1 hour work =1/20

B's 1 hour work=A's 1 hour work-(A+B)'s 1 hour work

=1/16-1/20=(5-4)/80=1/80

so,cistern will be emptied by B(leakage) in 80 hours
