a) 200
b) 160

Hi sana.noor,

I guess this is the error you have done

(560 - y) / (800) = 60%, which would give y = 80

But, when you are subtracting the people those who are retiring, you have to remove them from the number of total employees too.

Hence, the denominator would be (800 - y)

Hence the equation would be

(560-y) / (800-y) = 60/100.


That would give y = 200

a) 200
b) 160

OA is A
Current long-term = .7(800) = 560.
We can plug in the answers for the value of y.
Given that every value in the problem (800, 70, 60) is a multiple of 10, the correct answer choice almost certainly is itself a multiple of 10.

Answer choice B: 160

After 160 retire:
Remaining long-term = 560-160 = 400.
Remaining total = 800-160 = 640.
Resulting percentage = 400/640 * 100 = 62.5%.
For the resulting percentage to decrease to 60%, more long-term employees must retire.

The correct answer is A.
