10. Balance Puzzle
There are 9 coins, all except
one are the same weight, the
odd one is heavier than the
rest. You must determine which
is the odd one out using an old
fashioned balance. You may
use the balance twice.
Explain how this can be done.

11. Put 1,2 & 3 on the left side and 4,5 &
6 on the right side. There are three
possible outcomes:
• scale tilts left - means the heavy
coin is in group 1,2 & 3
• scale tilts right - means the heavy
coin is in group 4,5 & 6
• scale balances - means the heavy
coin is in group 7,8 & 9
Using one weighing we have successfully
narrowed three groups down to one. If it's
not completely clear how we can make the
assumption that the bad coins is in group 7,8
& 9 when the scales balance, remember we
know there is a bad coin, there has to be, we
have eliminated the other two groups, it must
be in the third.
We need to do the same again and
we will arrive at the final coin. Lets
label the three coins we have
narrowed it down to as A, B & C. Not
strictly necessary but it's easier to
explain. So if we'd narrowed it down
to 4,5 & 6 they would become A,B &
C respectively. Putting A on the left
side, B on the right and C to one
side.
• A goes down - A is the heavy coin
• B goes down - B is the heavy coin
• Neither goes down - C is the heavy
coin
