Holiday puzzles

Well, we’re off to France tomorrow for a couple of weeks or so, for our annual holiday. While we’re relaxing in the Ardeche, here are a few little puzzles for any reader who has nothing better to do.

1) Merlin rode out from Camelot on Tuesday and returned five days later on Tuesday. How did he manage that?

2) What do you get if you subtract 17 from 374 twenty-two times?

3) A farmer owns a large square farm. Every Monday morning he walks around the four sides of his farm.

It takes him ninety minutes to walk along the first side. He then stops for a drink from the well.

It takes him ninety minutes to walk along the second side. He then stops for a rest under a tree.

It takes him ninety minutes to walk along the third side. He then stops to chat to the milkmaid.

He then walks along the fourth side, but this takes him an hour and a half!

Can you explain why?

4) Which has more tails? One kangaroo or no kangaroo?

5) What is the probability that the first person you see on leaving your house tomorrow will have more than the average number of legs?

6) If someone agrees to answer yes or no honestly to two questions, how can you then get them to agree to anything? For example, to say ‘yes’ to the question: ‘Will you give me a thousand pounds?’

Au revoir.
