D) 80

800(0.7)=560

(560-Y)/800=0.6 --> Y=80

I backsolved this one and got 200. 80 yields 66% long term employees - 480/720 = 66.6%. 200 yields 60% 360/600.

X & Y, denominator should be (800-Y)...must take into account reduction in total number...

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

560 long timers ...

retired members = y , long timers after retirmemnt of y = 560-y

total employees AFTER RETIRMENT OF Y = 800-y

560-y / 800-y = 0.6

560-y = 480-0.6y thus

80 = 0.4y

thus y = 200
