Answer 2

Answer:

$\huge\mathbb\red{answer}$

$Let us call the pipe Pipe A.$

Pipe A fills the cistern in 6hrs

so in one hr Pipe A fills 1/6th of the cistern.

However with the leak it takes 7hrs for Pipe A to fill the cistern.

Hence in one hour the cistern will have 1/7th left in.

So the difference between not leaking and leaking is 1/6 - 1/7 = 1/42 th of the cistern

this is amount of leak per hour.

Hence it will take 42 hours to fully empty the cistern ,.
