The sum of the two ratios must be a prime number in order to satisfy the criteria of the employees

Only option (E) gives us a sum which is prime, so pick (E)

Can you confirm the OA?

Total=(a+b)*x

a=Number of emp who are graduates and above

a=Number of emp who are not graduates

Here a+b is prime and x=1

Only option E satisfy this.

Total=181*1

Pick E

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
