If the average weight of five friends A, B, C, D and E is 52 kg, then who is the heaviest among them?

I. A and E are neither the heaviest nor the lightest and only two friends among A, B, C, D and E have their weights more than the average.

II. B's weight is 40 kg, which is the lightest weight. The average of weight of D and E is 60 kg and the average weight of C and A is 50 kg.

It takes time and effort to explain, so if my comment helped you please press Thanks button

II. B's weight is 40 kg, which is the lightest weight. The average of weight of D and E is 60 kg and the average weight of C and A is 50 kg.

1. The statement is insufficient to conclude which one is the heaviest. A&E are ruled out, and 3 of A B C D E has less than 52kg weight

2. B's weight is 40 avg of D&E is 60 and avg of C&A = 50, the heaviest is one of D &E since the maximum weight C or A can have is 60 Kg - Insufficient

Combined A &E has less than 52 kgs D has the maximum weight

Sufficient

C

"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."
