Of the 800 employees in company X, 70 percent have been in the company for over 10 years. If y of these "long term" employees were to retire and no other employee changes were to occur, what value of y would reduce the percent of "long term" employees in the company to 60 percent?

I'm sorry, I didn't post the OA. The OA says it is 200.

[(800*70%) - y] / (800-y) = 60/100 => y=200

If y of these "long term" employees were to retire and no other employee changes were to occur, what value of y would reduce the percent of "long term" employees in the company to 60 percent? Total number of employees = 800 Number of "long term" employees = 70% of 800 = 560 After y "long term" employees retire, Total number of employees = (800 - y) Number of "long term" employees = 60% of 800 = 0.6*(800 - y) Therefore, 0.6*(800 - y) = (560 - y) => (480 - 0.6y) = (560 - y) => 0.4y = 80 => y = 200
