Solving each statements with number line properties, it's a call between C & E

consider 2 statements as linear equations & its C
1) More than 1/2 of the prices are $1,500 or more than $1,500
x>=1500
2) More than 1/2 of the prices are $1,500 or less than $1,500
x<=1500
median is 1500 (s1 & s2)

There are many variables in this case. Hence, there is high chance that E is the correct answer. Using 1) and 2), we can see that “more than 1/2 of the prices are $1,500 or more than $1,500” and “more than 1/2 of the prices are $1,500 or less than $1,500”. The overlapping price then will be $1,500. Thus, $1,500 becomes the median, and the correct answer is C.

- Forget conventional ways of solving math questions. In DS, Variable approach is the easiest and quickest way to find the answer without actually solving the problem. Remember equal number of variables and independent equations ensures a solution.
