Number of workers left on fourth days is 3 after which the remaining workers completed the work in 14 days

Given that  

A team of seven workers started a job, which can be done in 11 days.

On the morning of the fourth day, several people left the team. The rest of team finished the job in 14 days.  

Need to determine how many people left the team.  

Let say complete work be represented by variable W.

=> work done by 7 workers in 11 days = W

As its given that for three days all the seven workers worked.

Work done by 7 worker in 3 day is given as:

Work remaining after 3 days = Complete Work - Work done by 7 worker in 3 day

It is also given that on fourth day some workers are left.

Let workers left on fourth day = x

So Remaining workers = 7 – x

And these 7 – x workers completed remaining work in 14 days

As Work remaining after 3 days = and this is the same work done by 7- x worker in 14 days

Workers left on fourth day = x = 3

Hence number of workers left on fourth days is 3 after which the remaining workers completed the work in 14 days.

equation:

4=7-x

3 people left the team.
