The King calls in three wise men and tells them to all close their eyes. While their eyes are closed, he goes around and puts a hat on each of them.
“I put a blue or white hat on each of you,” the King says. “I won’t tell you what color each hat is, but I promise you that at least one of you has a blue hat.”
“Now open your eyes,” he continues. “You may not communicate with each other at all. Within one hour, one of you must call out the color of your own hat. If you aren’t able to do this, or if anyone calls out the wrong color, I will have you all exiled from the kingdom.”
The wise men open their eyes and look at the other mens’ hats. They stand there for almost the whole hour in silence, thinking. Just as time is about to run out, all three men figure out the color of their own hats and yell the colors out at the same time.
You can assume that all three men are perfect logicians, that they know that the others are perfect logicians, and that they all think at the same speed.
What colors are the three men’s hats? Riddle Answer

A poor farmer went to the market to sell some peas and lentils. However, as he had only one sack and didn’t want to mix peas and lentils, he poured in the peas first, tied the sack in the middle, and then filled the top portion of the sack with the lentils.
At the market a rich innkeeper happened by with his own sack. He wanted to buy the peas, but he did not want the lentils.
Pouring the seed anywhere else but the sacks is considered soiling. Trading sacks is not allowed. The farmer can’t cut a hole in his sack.
How would you transfer the peas to the innkeeper’s sack, which he wants to keep, without soiling the produce? Riddle Answer
