I have a problem for someone to figure out.  You are given 12 coins, 11 
of which all are of equal weight.  The 12th coin is not the same as the 
others, but you do not know if it is heavier OR lighter.  You are given a 
balance scale (two sided-scales of justice type) you are allowed to make 
three balances with it.  With this you must determine which coin is not 
like the others.  Remember you are only allowed to make THREE (3) 
balances.  I don't know the answer...this is why I am posting it. 

If anyone can help it would be much appreciated.
Thanks,
Steve
