Below are four (4) questions and a bonus question. 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!!

First Question:

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

Answer:  If you answered that you are first, then you are absolutely
wrong!

If you overtake the second person and you take his place, you are
second!

Try not to screw up in the next question.
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.

Don't believe it? Check with your calculator! Today is definitely not
your day. Maybe you will get the last question right?

Fourth Question:

Mary's father has five daughters: 1. Nana, 2. Nene, 3. Nini,
4. Nono.  What is the name of the fifth daughter?

Answer:  Nunu?

NO! Of course not.

Her name is Mary. Read the question again

Okay, now the bonus round:

There is a mute person who wants to buy a toothbrush. By imitating the
action of brushing one's teeth he successfully expresses himself to the
shopkeeper and the purchase is done.

Now if there is a blind man who wishes to buy a pair of sunglasses, how
should he express himself?
