Question

A project can be completed by 8 workers in 30 days. In order to complete the project sooner, the company plans to hire additional workers. How many total workers are needed to complete the project in 16 days?

Answer 1

Answer:15

Explanation:

Given

8 Workers can a work in 30 days

i.e. 1 workers can do the same job in
`8* 30=240\ days`

If additional workers is hired to do the same work in 16 days

suppose Now x no of workers do the job so, one worker will do the same job in
`x* 16`

No of days require to complete the job by one worker remains the same (considering all are equally efficient)

`240=x* 16`

`x=15\ workers`

So a total of 15 workers is required to do the same job in 16 days
