perplexus.info :: Weights and Scales : Twelve Coins and a Broken Scale

Twelve Coins and a Broken Scale (Posted on 2005-06-24)

You have 12 coins, six weigh 24 grams and six weigh 25 grams. You also have the broken scale from Five Weights and a Broken Scale.

Sort the 12 coins into the group of 24g coins and the group of 25g coins using that broken scale no more than 9 times.
