i shall give the first person to solve and explain the answer, best answer!

You have 12 coins, one of which is counterfeit, and a balance pan scale. The fake coin may be identified by the fact that it’s weight is different from the 11 genuine coins. Can you identify the counterfeit coin and whether it is heavier or lighter in three weighings?

You have a total of nine ancient gold coins in your possession. However, one of the coins is counterfeit. It appears identical, but it is slightly heavier han the other 8 coins. With a beam balance, what is the smallest number of weighings required, that would guarantee an accurate identification of the counterfeit coin? Please show all the weighings using a tree diagram outlining each possible outcome.
