all u have to do is find 14/9 and then multiply that by 41

Answer 2

As per the problem we have

It takes 41 minutes for 9 people to paint 9 walls.

It mean that 1 people can paint 1 wall in 41 minutes and only in that scenario when 9 people will work together with the same efficiency can paint 9 walls in 41 minutes.

Here only the number of walls and number of people changing not the time taken by each people.

So if we increase the number of walls and number of people in same proportions. Then time will remain same.

Hence it will take 41 minutes for 14 people to paint 14 walls.
