E

{16,18,22,24} and {12,18,24,26} satisfy both conditions but have different median.

1. In set S there are as many numbers bigger than 20 as there are numbers smaller than 20

{16,18,22,24}: 16,18 are smaller = 22,24 are bigger than 20
{12,18,24,26}: 12,18 are smaller = 24,26 are bigger than 20

What's wrong?
