  Angelina has 25 gold coins. One on those coins is lighter, while the rest of the coins have the same weight. If Angelina has a balance, how would Angelina determine which coin is the lighter one with 3 weightings?
  
  

  Divide the coins into 3 group consisting of 9 coins, 9 coins, and 7 coins. On the first weighing, weigh the 2 groups of nine coins. If they have the same weight, then the counterfeit is in the group with 7 coins. If one of the groups of 9's weighs less, then the counterfeit is on that group.

  On the second weighing, divide the group where Angelina knows the counterfeit coin is into 3 subgroups, where the first two subgroups would have 3 coins each. Weigh these first two subgroups. If they have the same weight then the counterfeit is on the third subgroup. If one of them weighs less, the counterfeit is on the subgroup that weighs less.

  Since the subgroup that contains the counterfeit has at most 3 coins. Weighing two of these coins will allow Angelina to know which coin is the counterfeit.
