Hi - I'm struggling with question 37 - could you help:

Is the average of a set of 5 distinct positive integers { a, b , 4, 6, 2} greater than the median?

1. the highest number in the set is 6
2. the lowest number in the set is 2

I picked E. I agree with the OA that 1 and 2 are insufficient. What I don't see is how they are sufficient together (OA is C). For example, if a=2,b=2, the average would be 16/5 or 3.2 while the median would be 2 - so the average would be greater than the median. However, if a=3,b=5, then the average and median are the same (4). How is E not the OA? Please help!

Thanks
