From 1) 25% = 4 employees or more
Not sufficient since 50%(median) could be 1,2 or 3 employees
2) 35% = 2 employees or less
Not sufficient since 50% could be 3,4, infinity
We know from both combined that x(median, 50%) is b/w 2 and 4. And since x has to be an integer(a human being), it can only be 3.
