GMAT Prep --- Long term employees

[animesh]

Of the 800 employees of 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%?

1. 200
2. 160
3. 112
4. 80
5. 56

[Unna100]

Total Employees : 800
Long Term Employees : 70% * 800 = 560
If % needs to reduce to 60% , 60% * 800 = 480
So 560-480 = 80 of them will retire.
Answer Choice : 4

[avikar]

A (200)

current long term employees = 70%* 800 = 560

(560-y) = (800 -y) * 0.6 ==> y = 200

A for me

[animesh]

Good answer Avikar. I made the same mistake as Unna10

[rising j]

great answer. I, too, intially made the same mistake. For anyone else who will come across this..., make sure you adjust the final value of the "total", to account for the loss of y employees, and not just take the 60% from the initial value of the total.
