Which is heavier a real coin or a counterfeit coin?
There are 16 coins, 3 of which are slightly heavier or lighter than the others.

How to figure out if a coin is real or fake?
The following diagram explains the procedure. The middle case (G1) = (23) is self explanatory, i.e. 1, 2, 3 are genuine and 4th coin can be figured out lighter or heavier in one more trial. The left side of tree corresponds to the case (G1) < (23). This is possible in two ways, either 1 should be lighter or either of (2, 3) should be heavier.
Can you put a fake coin on a balance scale?
Solution. One weighing. Place one coin on one side of the balance scale, one on the other, and put one coin aside. If the scale balances, the coin that we put aside is fake. If one of the sides of the scale is heavier, the fake coin is on that side. Example 2. One of the nine identically looking coins is fake.
