Gmatrant,
Median of the six numbers = (6 + 8) / 2 = 7
AM = (33 + x) / 6
So (33 + x)/6 * 6/7 = 7
so x = 16
IMO A. What do u say, Gmatrant?

x can be even 7 or even 2.6, then the median would change, so how can u take 6+8, it can be anything..camitava wrote:Gmatrant,

The median will be (6+8)/2 because the numbers are arranged in their increasing order. So the median has to be the average of the 2 middle digits.
