This was asked in an interview with Coa-Cola.

The interviewer has given me 100 marbles(50 white and 50 black) and two empty boxes.
He then told me that he will leave the room and i need to place all the marbles in two boxes.

And When he come back, he will draw a marble from any of the two box and if the marble is white I will be hired.

Also
* No box can be empty.
* All 100 marbles must be placed in one of the two boxes.

So what should I have done?

You have an empty wine bottle with a cork that has been secured at the top in a normal way. There is a metal ring inside the bottle that is suspended by a string.

How can you make the metal ring drop to the bottom if you are not allowed to touch anything - not the bottle, not the cork, not the thread and not the ring?

Can you arrange four 9's and use at most 2 math symbols, to make the total 100?

The product of three consecutive numbers is 7980.
Then the sum of these consecutive numbers would be?

As easy as you can get into me, it is as hard to get out of me.

Do you know what I am?

What part of the chicken has the most feathers?

If you toss a coin 10 times and it lands heads up every time, what are the chances it will land heads up if you toss it again?

You knock a Table over in the library, and suddenly 20 eyes are looking at you.

They do not possess flesh or feathers or scales or bone
But still, they are blessed with fingers and thumbs of their own.

From a pack of 52 cards, I placed 4 cards on the table.

I will give you 4 clues about the cards:

Clue 1: Card on left cannot be greater than the card on the right.
Clue 2: Difference between the 1st card and 3rd card is 8.
Clue 3: There is no card of an ace.
Clue 4: There are no face cards (queen, king, jacks).
Clue 5: Difference between the 2nd card and 4th card is 7.

Identify four cards?
