This weeks Lesson tasks is about idea development. The first lesson this week was to answer four riddles.
1st riddle:
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:
The girl happens to work in the Water and Sewerage Department and has access to the drain system. She finds the nuts and hands them over to the man. The man attaches the wheel to the car and drives home.
2nd riddle:
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:
The other russian is the mother of the son, which means they are mother, father and son.
3rd riddle:
What occurs once in June, once in July and twice in August?
My answer:
There is one “u” in June, one “u” in July and two “u’s” in August.
4th riddle:
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:
You take glass number 2 and pour the water into glass number 5. The minimum of moves is therefore only one move.
