Of the 800 employees in a certain company, 70% have serviced more than 10 years. A number of y of those who have serviced more than 10 years will retire and no fresh employees join in. When is y if the 10 years employees become 60% of the total employees?
560 employees have serviced more than 10 years.
Let y employees leave the company
(560-y)/(800-y) = 60/100
56000 - 100y = 48000 - 60y
40y = 8000
y=200
200 of these employees have to leave.
