Fred, who owns a restaurant, is convinced that one of his employees is stealing root beer from him. Since he is a bad businessman, he doesn't keep very good records of his inventory or his employees, so he doesn't know who is doing it. He decides to set a trap to find out who is stealing from him.

He assigns each of his employees a different night to close up shop. He then arranges the last 28 bottles of root beer in a square so that each side has nine bottles, as shown below:

2 5 2
5 0 5
2 5 2

Fred figures that whatever day he comes in where there are no longer nine bottles to a side, he will know it was the person who closed the night before who is doing it.

In a far-off kingdom, it is well known that the only way to counteract being poisoned is to drink a stronger poison, in order to neutralize the weaker one. Long ago, the king who ruled this kingdom wanted to ensure that he possessed the strongest poison in the kingdom, to ensure that he could counteract any attempts on his life.

So the king called the royal treasurer and the kingdom's best pharmacist. He gave each the task of concocting the strongest poison possible within one week. At the end of this week, each of the two men would drink the other's poison, followed by his own -- whoever survived, succeeded.
