Steven has nine gold coins that are identical in appearance but one is counterfeit using a balance scale how can he find the counterfeit in just two weighings?
The idea is that the counterfeit coin is lighter than the others, but not different enough to find by hand.
- Divide the coins into 3 groups of 3. Reserve one group and put the other two groups onto the balance scale.
- If they are the same, the counterfeit is one of the reserved group. Otherwise, the lighter pan has the counterfeit.
- Put one coin on each side of the scale and keep one off. If they are the same, the one not weighed is the counterfeit. Otherwise it is the lighter one.

If you get paid three bags of gold but one is fake how do you determine which one it is?
If you are certain two bags contain real gold, and if the three bags are supposed to be identical, then do the following. Find a balance scale. Take two of the bags and place one on each pan. If the scales balance, then the third one is bogus. Execute the guy who gave you that bag. If the scale fails to balance, you'll have to make another comparison. Remove the lighter bag and replace it with the third bag. If the scales balance, then the one you removed is bogus. Commence executions. If the scale fails to balance, then the heavier bag is bogus. Execute the fraud.
Which is heavier 8 marbles that are exactly alike except that one of them is slightly heavier than the others I then give you a balance scale and ask you to determine the heavier marble in 3 weighings?
Weighing 1: Weigh any four against any other four. The set containing the heavier marble will be heavier. Weighing 2: Weigh any two from this heavier set against the other two from the set. The pair containing the heavier marble will be heavier. Weighing 3: Weight the two marbles from the heavier pair against one another and you have the odd marble. Simple!
