Puzzle 9

You drive a bus, and 18 people are riding it. At the next stop, 5 get off but 13 get on. When you reach the next station, 21 get off and 4 more get on. What color are the driver’s eyes?

Riddle 10

A farmer has 10 rabbits, 20 horses, and 40 pigs. If we were to call the pigs “horses”, how many horses does he have?

A boy looking through a magnifying glass.

Were these difficult for you? How many do you think you got right?

Here are the answers so you can see for yourself how well you did:

  • Answer 1. One five-dollar bill and one one-dollar bill. John’s father tells his son that one of them isn’t a one-dollar bill… but the other could be.
  • Answer 2. The last day of fall because it’s the shortest day of the year.
  • Answer 3. 11. Let’s consider the worst case scenario, where John picks up all 10 right (or left) gloves of either color. This would make it impossible for him to have a match. Just one more would be enough to complete a pair.
  • Answer 4. Only once, because after that you’d be subtracting it from the numbers 1110, 1109, 1108…
  • Answer 5. Her mother.
  • Answer 6. Second.
  • Answer 7. If they fall from the first floor. The riddle doesn’t say what floor the person falls from.
  • Answer 8. The parrot is deaf.
  • Answer 9. The color of your eyes!
  • Answer 10. You’ll still have 20. Giving them another name doesn’t transform them into horses.

Riddles are great!

Riddles that will test your mind often make you try something called lateral reasoning. This is a type of reasoning that consists of solving problems in a creative way, as defined by Edward de Bono in 1967.

Throughout history, several puzzles have been designed that seem like traditional problems but test the logical principles and cognitive abilities of the person who has to solve them, helping them exercise their brain.

Lateral reasoning is different from the linear or direct reasoning that most of us are used to.

In the traditional way of reasoning, you progress logically from one step to the next, while with lateral reasoning you deliberately have to abandon that process. This forces you to set aside certain inhibitions. This forces you to solve problems in different ways.

Ultimately, having to deal with tasks that are “different” exercises the brain. This is why puzzles are ideal for training the brain and have health benefits. We hope you enjoyed these riddles that will test your mind!
