#### what fraction of c

###### Problem Solving

Actually just read the question again. It is pretty simple. The only thing to note is that for a set of consecutive integers the median is same as the mean. Use this and the solution is pretty simple.

#### Manhattan gmat DS question - doesn't make sense
