Question

10 people can fill water tank in 20 hour so how much people neede to filll up tank in 5 hours

Answer 1

Step-by-step explanation:

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 4o persons are required to fill up the tank.
