"A Test" joke

Below are three (3) questions. You have to answer them instantly.
You can't take your time, answer all of them immediately. OK? Let's find out just how clever you really are. Ready? GO!!! (scroll down)

First Question: You are participating in a race. You overtake the second person. What position are you in?

Answer:
If you answer that you are first, then you are wrong!
If you overtake the second person and you take his place, you are second!

To answer the second question, don't take as much time as you took for the first question.
Second Question: If you overtake the last person, then you are...?

Answer:
If you answered that you are second to last, then you are wrong again.
Tell me, how can you overtake the LAST person?! You're not very good at this are you?

Third Question: Very tricky math! Note: This must be done in your head only. Do NOT use paper and pencil or a calculator. Try it.
Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another 1000. Now add 20. Now add another 1000. Now add 10. What is the total?

Did you get 5000? The correct answer is actually 4100.
Thought this was cute! Don't believe it? Check with your calculator! The decimal sequence confuses our brain, which always jumps to the highest decimals (100s instead of 10s).
