Answer:

$\large \green{Solution}$☟︎︎︎

We can use the concept of Ration here as Persons Time (Hours)

10 20

x 5

There will be an inverse proportion between the two as time decreases persons will increase so we can write the equation as:

x/10=20/5

x=(20/5)*10

x=40

So 40 persons are required to fill up the tank in 5 hours.

$\large \green{Answer}$➪ 40 .
