All right mate.. i almost failed to see the trap. Only cos you said this is a trap, i saw it. Good question.

Total T=800
Current # of Long timers = 560 (70%)
Current # of short timers = 240

if y old timers leave and nothing else happens, then

(560-y)/ (560-y+240) = 0.6 solving we get y=200

x = 800

(70% of x - y) = 60% of (x-y)

solve for y:
y = 200
