Question 1
Practical assignment (puzzles and fun): 1‑2 hours
Think about the following four riddles and give your answer to each. The purpose is that you should have fun in figuring these out. Why not get a group of friends together and see if you can come up with some creative solutions?
- A man is replacing a wheel on his car, when he accidentally drops the four nuts used to hold the wheel on the car. They fall into a deep drain, irretrievably lost. A passing girl offers him a solution that enables him to drive home. What is it?
Answer: The girl tells him that he can take one bolt from each of the other tires so he gets three bolts on each tire.
- Two Russians walk down a street in Moscow. One Russian is the father of the other Russian’s son. How are they related?
Answer: They are husband and wife. - What occurs once in June, once in July and twice in August?
Answer: The letter “u”, and it’s also the second letter in all of those three months. - Six drinking glasses stand in a row, with the first three full of water and the next three empty. By handling and moving only one glass at a time, how can you arrange the six glasses so that no full glass stands next to another full glass, and no empty glass stands next to another empty glass? What is the minimum number of moves to solve this puzzle?
Answer: Since it doesn’t say anything about how you are supposed to move the glass I would just pour the water that’s in the second glass over to the fifth glass.
