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

It will take 14 painters 18 days.

Explanation:

It was given that, 12 painters paint the walls of a school in 21 days.

If the number of painters increased to 14, then it will take less number of days to paint the walls of the school, working at the same rate.

If less, then more will divide.

The number of days

`=(12*21)/(14)`

`=(252)/(14)`

`=18`
