Question

20 people can complete a particular job in 60 days . If the job has to be completed in 50 days, how many more people are required?

Answer 1

As , in 60 days 20 people can do a job.

So, in 1 day 20 x 60 people will do that job.

Therefore , in 50 days ( 20 x 60 ) / 50 people will do that job.

                                   = 1,200 / 50

                                   = 24 people.

So, 24 peoples will do that job in 50 days.

So, more number of people = 24 - 20 = 4.

Therefore , your final answer is 4.
