I think they're hard and haven't read the answers so please think about it with me:
Brain Teaser #1: The King and His Coins (Difficulty Level: Easy)
Brain Teaser #2: The Oldest Child (Difficulty Level: Difficult)
Two men that haven’t seen each other in many year ran into each other in the street. The first man says to the second that it’s great to see him after so many years and asks weather he has a family or not. The second man replies that he does have a family and that it consists of a wife and three children. The first man then inquires about the ages of the three children. The second man answers this question in the form of a riddle. He says that the product of his three children’s ages is equal to 36 and that the sum of the their three ages is equal to the number of the blue house on the corner of the road. Further, all of the ages are exact unit numbers and no fractional equivalents should be used. The first man walks up to the blue house on the corner, looks at the number, and returns to the second man. The first man then states that the second did not give him enough information to solve the riddle. The second man replies that the first man is correct and that one additional clue is needed to solve the riddle. The second man smiles and says that his oldest child’s eyes are blue. The candidates task is to tell you the ages of the three children and correctly identify the number on the house.
The typos are not mine...they were like this in the packet lol.
