The range is the difference b/w smallest and the largest values of the set.

To make the range 30, x could take only 2 values
-45 or 30

The median is the middlemost value of the set when the numbers are arranged in ascending (or descending) order. Arranging the constants in ascending order,

We get 0,3,10,15

now if x is -45, the median is 3
and if x is +30, the median is 10

so median could be any of 3 and 10

Correct answer is E
