800 Emp

by mmslf75 » Sat Dec 19, 2009 8:24 am
Of the 800 employees of company X,70% have been with the company for last 10 years.if y of those long term members were to retire and no other employee changes were to occur,what value of y would reduce the percent of longterm employees in the company to 60%?

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

OA is A


Why do we subtract Y from 800 to get to the answer

I went wrong on this one..and marked D instead.

I thought that 60 % of 800 = 480 and 70 % of 800 = 560
560-480 = 80

Wht did i miss ?

you've to reduce from 560 ( longterm employees)
560 reduced to 60% i was getting 224 so in given answers 200 fits the bill

70% * 800 = 560 long term employees

If you reduce the number of long term employees by "y" then of course you reduce the entire pool of employees also by "y", that's what you're missing

The problem is asking for the resulting percentage AFTER the reduction to equal 60%, so necessarily

(560-y)/(800-y) = .6 and y=200
