Question

It takes 16 minutes for 9 people to paint 8 walls.

How many minutes does it take 4 people to paint 6 walls?

Answer 1

I think it is 27 minutes

Answer 2

Answer: 4 people take 27 minutes to paint 6 walls.

Explanation:

Since we have given that

Number of people to paint 8 walls in 16 minutes = 9

We need to find the time taken by 4 people to paint 6 walls.

We will use "Time and Work " rule :

`(9* 16)/(8)=(4* x)/(6)\\\\18=(2)/(3)* x\\\\18* (3)/(2)=x\\\\9* 3=x\\\\27=x`

Hence, 4 people take 27 minutes to paint 6 walls.
