Question

It takes 22 minutes for 10 people to paint 10 walls. How many minutes does it take 14 people to paint 14 walls?

Answer 1

220pm=10w (people*minutes)

w=22pm

14w=308pm

308pm/14p=22m

So it would take 22 minutes for 14 people to paint 14 walls.

Answer 2

Answer: 22 minutes

Explanation:

Since, if
`x_1` people take
`n_1` days for doing
`w_1` work while
`x_2` people take
`n_2` days for doing
`w_2` work,

Then,

`(x_1* n_1)/(w_1)=(x_2* n_2)/(w_2)`

Here,
`x_1 = 10`,
`n_1=22\text{ minutes}`,
`w_1=10`
`x_2=14` and
`w_2=14`,

By substituting these values in the above equation,

We get,

`(10* 22)/(10)=(14n_2)/(14)`

`\implies (2200)/(10)=n_2`

`\implies 22=n_2`

Hence, the time taken by 14 workers making 14 walls is 22 minutes.
