Tips for Ties

Three young intelligent guys at the same time run up to the consultant in tuxedos for black bow ties. The consultant, at a loss, checking the number, informs the young people that there are only two blacks left, and one of them has already been ordered by another buyer.

On the proposal to take all the whites, young people begin to resent and argue with each other about who still gets a black tie. The consultant turns for help to the manager to solve such a delicate situation.

The manager, assessing the situation, offers the guys a quick-witted challenge.

“You see,” he says, “I have 5 ties, 3 white and 2 black.

He asked them to close their eyes and put on a white tie for everyone, and hid the black ones in his pocket.

- You can open your eyes. And now, whoever first says what color of tie on it, he has the right to buy the same black one.

The guys stood for a few minutes, not looking at each other ... Finally, one exclaimed:
- On me - white!

How did he guess?

PS The correct answer immediately gave si1v3r . The task is not so difficult, but interesting enough, if someone had not heard about it before. The implication is that young intelligent guys have an IQ of no lower than average, which makes it possible to get an answer.

The correct answer from nullie :

1. If there are two black ties in a game, then one of the participants sees two black ties, and understands that he is wearing white. Once no one answered, it means one tie.
2. If the tie is one, then two participants see a black tie, and, applying the logic of paragraph 1, they understand that they have a white tie.
3. Since no one has yet answered, it means that there are no black ties in the game, and ties for all are white.
