A company has 400 employees, 20 percent of whom have 5 or more years of work experience. If 40 additional employees are to be hired and all of the present employees remain, how many of the additional employees must have 5 or more years of work experience in order to raise the percentage of employees with 5 or more years of work experience to 25 percent?
A. 10
B. 15
C. 20
D. 25
E. 30
The OA is E.
It can be solve as follow,
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, right?
Is there another strategic approach to this question? Can any experts help?
