How did you arrive at C ?

Other than {2,3,4,5,6} is there any other set which has range and average equal. I am struck there. What is easy way to crack this ?

I think the statement B was kind of time consuming to crack. You have to try different combination. One thing we can think of is that we are already given that the range and the average are equal, With statement 2, we are also given that the numbers are different. So the numbers must be evenly spaced so that the middle number could be the average and the numbers are equally dispersed on both sides of the middle number. This was all just my hunch. Not sure if that is true.

Anyhow, from statement 2 , we have another combination 4, 6, 8, 10, 12

Even after this you will have to apply a little logic to arrive at the answer C. I would leave it for others and you to try.
