Here is a very cool test. Sorry if the translation is not good.
Answer quickly, don't lie.
1. You are in a running competition. You outrun the player on second position. On which position are you now?
Answer: If you answered on first, then you are absolutely wrong. Yoo have outrun the second runner and you have taken his position - second.
Try not to mistake this one:
2. You have outrun the player on the last position. On which position are you now?
Answer: Before the last? No. Think. How can you outrun the player on the last position? It appears that using your brain isn't the best thing that you can do.
However, here is one more question. Don't use calculator, don't write anything and remember - answer quickly.
3. Take 1000. Add 40. Add 1000. Add 30. Add 1000. Add 20. Add 1000. Add 10. What is the result?
Answer: 5000? Yet again - WRONG! It's 4100. Don't beleive? Use calculator.
Maybe you will answer correctly the last question.
4. Mery's father has 5 daughters. 1. Tata 2. Toto 3. Tutu 4. Titi. Question: What is the 5th daughter. Think quickly.
Answer: Tete? NO! It's Mery of course. Read the question again.
