View full lesson: http://ed.ted.com/lessons/can-you-solve-the-counterfeit-coin-riddle-jennifer-lu You're the realm's greatest mathematician, but ever since you ....
- So the Emperor is patient enough to wait 15 minutes until I gave up but can’t tolerate a 4th weighing?
- Isn't it easier if you have 3 stacks of 4 coins and if two stacks are balanced,to split third stack into 2 stacks of 2.Than balance those two stacks and see which is heavier/lighter.Then you balance those two coins left and see which is lighter/heavier.Am I right?
- You could put 6 on each, take the lighter 6, put 3 on each, take the lighter pile, then measure 2 of the 3 against each other. If they’re the same the coin is the one you didn’t weight or it’s the lighter one.
- There is actually a more elegant solution. You do 2 weighings, look at the results and do one more. I will name each coin by a number, so the first coin is one, the second is two etc.First, weigh coins 1,2,3, and 4 against coins 5,6,7, and 8. Next, weigh coins 2,3,4, and 5 against coins 6,7,8 and 9.Depending on the results of these weighings, you weigh the three coins that may be the fake coins (you know which ones these are because you can eliminate the other 9 options). The weighing will depend on the result of the first two weighings.Challenge: Can you find these weighings?
