Hi Turkish,

This question can be solved by TESTing THE ANSWERS.

We're told that a company is comprised of 60% female employees. After hiring an ADDITIONAL 20 male employees, the company is then comprised of 55% female employees. We're asked for the TOTAL number of employees that the company had AFTER hiring the 20 additional male employees.

We need to start with the initial group of employees, which means that we have to SUBTRACT 20 from each of the answer choices before we start our calculations.

Let's TEST Answer B: 220

220 - 20 = 200 original employees

60%(200) = 120 females

After the 20 males were hired...

120/220 = 12/22 = 5/11 = .4545 = about 45.5% female

This is TOO SMALL. Eliminate B.

Let's TEST Answer D: 360

360 - 20 = 340 original employees

60%(340) = 204 females

After the 20 males were hired....

204/360 = 51/90 = 17/30 = 56.666 = 56 2/3% female

This is TOO BIG. Eliminate D.

Since Answer B is too SMALL and Answer D is too BIG, the correct answer MUST be between these two...

Final Answer:

GMAT assassins aren't born, they're made,
