Question

if 4 people can paint the inside and outside of a cottage in 12 days. How many days would it take for 6 people to build the same cottage?

Answer 1

Since 4 people takes 12 days painting

6 people takes the following

`4people*12days=48people-days`

4 people in 12 days takes an effort of 48 people-days

`(48people-days)/(6people)=8days`

6 people takes 8 days to build the same cottage
