In this week learning activities we had to come up with a solution on four riddles. This was a tricky task at first, but when I had thought about them for some days I came up with a solution. Without sneak peeking on some other students blogs.

• 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?

The passing girl told the man that if he just take one nut from each of the wheels, so the wheels have only one nut, he can drive home himself with his car.

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

They are the father and mother.

• What occurs once in June, once in July and twice in August?

This was a tricky one and the last I figured out. But of course the U in the words occurs in the words June, July and August.

• 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?

Take glass number two and fill the empty glass number five, you can to it in just one move!
