Answer 1

Given:

A project can be completed by 75 workers in 40 days. But project manager

brought 15 more workers after 8 days

To find:

In how many days will the  remaining work be finished

Solution:

Let the number of days are required to complete the work is D

It is given in the question that 75 workers will complete the work in 40 days and they had worked for 8 days.

and after that project manager employed 15 more workers

So now the total number of workers is 90

• 75×32 = 90×D
• 5×32 = 6×D
• D = 5×16/3
• D = 80/3

In 80/3 days the remaining work will complete
