20% of 400 is 0.2 * 400 = 80 employees with 5 or more exp.

If that company hires 40 new employees, the total employees are 440.

25% of 440 is 0.25 * 440 = 110 employees with 5 or more exp.

The additional employees with 5 or more exp are: 110 - 80 = 30

The answer is E.

I think this question is sub 600 level.

We are given that a company has 400 employees and that 0.2 x 400 = 80 employees have 5 or more years of work experience.

We need to determine, if 40 more employees were hired, how many of those employees would need to have 5 or more years of work experience in order to raise the percent of employees with 5 or more years of work experience to 25 percent.

We can create the following equation in which x = the number of additional employees who have 5 or more years of work experience:

(80+x)/(400 + 40) = 25/100

(80+x)/440 = 1/4

4(80+x) = 440

80 + x = 110

x = 30

Answer: E
