EY Numerical Reasoning Test

You need 'nine additional freelance working days to get the project completed.' These working days can consist of two freelance programmers working together rather than just one working for the entire nine days. This is even preferable, as it is stated that the project must be completed in the shortest amount of time. (it can take less than nine days if there is an overlap between the two freelance programmers’ working days).

Because the freelancers work three, four, or five days a week, the best way to manage the nine working days is to employ one freelancer that works five days a week, and one freelancer that works four days a week. Together they will work for nine days and complete the project in a week.

Between the two freelancers who work five days a week, it will be cheaper to choose Freelancer 2 with a day rate of £164.
Between the two freelancers who work four days a week, it will be cheaper to choose Freelancer 5 with a daily rate of £170.

The cost will be

If you choose answer A, you calculated freelancers 2 and 5 worked only one day each.

If you chose answer C, you calculated freelancer 2 worked the whole nine days. He may do the job the quickest of all freelancers, but it will still take him two weeks while adding another freelancer would mean completing the project in only a week.

If you chose answer D, you calculated that Freelancer 3 worked the whole nine days. He is cheap, but it will take him three weeks to complete the project.

If you chose answer E, you chose freelancers 1 and 2, instead of 1 and 5. Freelancers 5 and 2 work the same amount of days, but Freelancer 5 is cheaper.

The correct answer is B: £1,500
