Question

It takes 12 painters to paint the walls of a school in 21 days. In how many days the same job will be completed with 14 painters?

Answer 1

18 days.

Explanation:

We have been given that 12 painters paint the wall of a school in 21 days.

So the wall painted by one painter will paint the wall in
`21* 12\text{ days}=252\text{ days}`

As one painter will paint the wall in 252 days, so to find the number of days it will take to paint the same wall by 14 painters, we will divide time taken by one painter (252) by 14.

`\text{Time take by 14 painters to paint the wall}=(252)/(14)`

`\text{Time take by 14 painters to paint the wall}=18`

Therefore, it will take 18 days to paint the same wall by 14 painters.
