Lapatulllka [165]

Answer:

3 people left

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

After 3 days, job left:

(11 - 3)*7 = 56 people*days

This was completed by 7 - x people as x people left

Time needed was 14 days, we have new equation:

14(7 - x) = 56
7 - x = 4
x = 7 - 4
x = 3

As we found, 3 people left
