Twelve Coins and a Broken Scale (Posted on 2005-06-24) Difficulty: 4 of 5
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.

Solution Solution (By Ed Mekler and Chris Longfellow | Comment 6 of 8 |

It's a broken scale, you can't solve this because you cannot weigh the coins correctly with a broken scale.
