LA week 2 – Puzzles

As part of this weeks LAs there were listed four puzzles for us to solve.

Puzzle one: 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?

My answer: She jumps in the passenger seat and lets him drive her car home. I’m quite certain she is his sister, by the way. As she loves him and doesn’t want him to take unnecessary risks, she does not mention that he could have used one nut from each of the other wheels to drive home. That would not have been safe.

Puzzle two: Two Russians walk down a street in Moscow. One Russian is the father of the other Russian’s son. How are they related?

My answer: They are a couple, I would presume. Or at least they once were.

Puzzle three: What occurs once in June, once in July and twice in August?

My answer: The letter “U”.

Puzzle four: 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?

My answer: I would take the middle full glass and pour the water into the middle empty glass, before putting it back. Assuming that counts as one move, the answer is one.
