just looking at this
median is the middle number, so
1-35% have 2 or less emp, thats fine (10% with 1, and 25% with 2)
35 to 76% have 3,
76-100% has 4 or more emp, (there could be a very large number of groups much greater than 4, so you don't know that the median is)

i think it is E

Well, the question is the median number of employees per project for the projects. So, we are not looking at the median of employees, but the median of projects and whatever employee number lies at the median, would be the answer.

Since projects with 3 employees lie in the 50% range, it would be 3.

Correct me if I'm wrong here.

I agree answer should be median number of employees assigned per project = "3" (C)

from 1 and 2, we know how many projects have 2, 3 and 4 employees respectively.

Arrange each of these in arranging order of [employees/project], this will be the distribution:

2, 2, 2 ....... 3,3,3.....4,4,4 ....

Given the numbers, 3 will fall at 50 percent
