Why can't the rest 100-(25+35)=40% be at an even higher band (eg 5 employees or more) ?
Statement 1: 25% of the projects have each been assigned 4 or more employees.
Thus, if a project has been assigned 5 employees, or 6 employees, or 100 employees -- or any number of employees 4 or greater -- then it is contained within this 25%.
Statement 2: 35% of the projects have each been assigned 2 or fewer employees.
Thus, if a project has been 2 employees or 1 employee, it is contained within this 35%.
Statements 1 and 2 combined:
Thus, every project that has not been assigned 4 or more employees or 2 or fewer employees -- in other words, every project that has been assigned
exactly 3 employees -- is contained with the remaining 100-25-35 = 40%.
Listing the projects in increasing order, we get:
1,1,1,1,2,2,2,2....3,3,3,3,3,3,3.....4,5,5,6,7,8....
<----35%-->....<----40%----->....<---25%--->
Median = 3.
Sufficient.
The correct answer is
