Answer:
Step-by-step explanation:
- The job can be completed by 7 people in 11 days
- The job is equivalent of 7*11 = 77 people*days
<u>After 3 days, job left:</u>
- (11 - 3)*7 = 56 people*days
This was completed by 7 - x people as x people left
<u>Time needed was 14 days, we have new equation:</u>
- 14(7 - x) = 56
- 7 - x = 4
- x = 7 - 4
- x = 3
As we found, 3 people left
