If set S={2,5,1,x,7}, what is x ?

(1) The range of set S is 8

(2) The median of set S is 2

The answer given is : C

cant x take different values such as : 1.1, 1.2 , 1.3... and hence answer should be E ?

For answer to be c , should it not be mentioned that its an integer set?

I hope i am not missing something.

I think there is no need to write that it is an integer, because x can take fractional values, but no fractional value could be found if both statements taken together. For example you cannot find a fractional number with which you can have the range of 8 in the set with the biggest number 7.

I hope that helps.
