If the mean of set $$S$$ is 20, what is the median of set $$S$$ ?

In set $$S$$ there are as many numbers larger than 20 as there are numbers smaller than 20.
All numbers in set $$S$$ are even integers.

I used number testing to solve this problem but took me a really long time to figure out the right set of numbers. Can someone please suggest how to quickly come up with the right type of sets (numbers to be tested) for such problems.

This problem took me more than 3 minutes to solve, does anyone know some quick method to solve it or strategic guess?

The set may or may not contain negative numbers.. hence E
