Hi all, not sure if I'm mis-reading the question or not, but I can't determine how GMATprep's solution for the following question

Of the 800 companies in Company X, 70% have been with the company for at least 10 years. If y of these "long-term" members 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%.

A) 200
B) 160
C) 112
D) 80
E) 56

My answer was D, but the software says A is correct.

Here's my reasoning: 70% of 800 = 560 long-term employees

(560 - y) / 800 = .6
y = 80

What am I doing wrong?

another way is....
currently you have 240 short-term employees
after reduction....these will constitute to 40 %
240 is 40% of what....600

[240/x = 40/100
solving, x = 600]

So you have now 360 long term employees which is 200 less than current 560 ( .7 * 800)
