Is there such a thing as a 12 COIN puzzle?
They’re known collectively as balance puzzles, and they can be maddening…until someone comes along and trots out the answer. Within the world of balance puzzles, the 12-coin problem is well-known (there’s also a nine-coin variant, and a horrendous 39-coin variant).
Can you make two piles of 10 coins?
You are blindfolded and 10 coins are place in front of you on table. You are allowed to touch the coins, but can’t tell which way up they are by feel. You are told that there are 5 coins head up, and 5 coins tails up but not which ones are which. Can you make two piles of coins each with the same number of heads up?
How can you tell if 12 coins are the same?
1) All 12 coins look identical. 2) Eleven of the coins weigh exactly the same. The twelfth is very slightly heavier or lighter. 3) The only available weighing method is the balance scale. It can only tell you if both sides are equal, or if one side is heavier than the other. 4) You may use the scale no more than three times.
How many identical coins are in a balance scale?
You are given 20 identical coins. 18 of those coins have a weight of 10g each, 1 coin has 9g and 1 coin has 11g. You are given a traditional balance scale with two pans (no reading).
What happens if you have four coins and cant find the odd one?
In this case you fail if it balances. You have four coins and can’t find the odd one in one weighing, because there are three places for coins (two pans and off the balance), so there will be two unknown coins in the same place. This shows three are required. Highly active question.
What happens if two of the three coins balance?
Take two of those three coins and weigh them against each other. If the balance tips then the heavier coin is the odd one out. If the two coins balance then the third coin not on the balance is the odd one out and it is heavier. 2.c) The three remaining coins balance.
