Solution

The correct option is C Both statements together are sufficient, but neither statement alone is sufficient.
  1. Although 25 percent of the projects have 4 or more employees, there is essentially no information about the middle values of the numbers of employees per project. Thus, statement 1 is not sufficient.
  2. Although 35 percent of the projects have 2 or fewer employees, there is essentially no information about the middle values of the numbers of employees per project. Thus, statement 2 is not sufficient.
  • Given both (1) and (2) statements, 100 - (25 + 35) percent i.e equal to 40 percent of the projects have exactly 3 employees. Therefore, when the numbers of employees per project are listed from least to greatest, 35 percent of the numbers are 2 or less and (35 + 40) percent = 75 percent are 3 or less, and hence the median is 3.
