This one is compliments of some of my college friends. I wasted almost two
hours on this one...
You are given 12 balls and a balance. One of the balls is either lighter or
heavier than the rest (you don't know which). In three uses of the balance,
figure out which is different.
Want a hint?
Think you know the answer?
Send me email
with your solution. You won't win anything,
but if you like I'll add your name to the "
List of People With Too Much Free Time".
