1. Once upon a time, there was a herder who had an unfinished business when he died. He just wanted to give 1 17 sheep to his three sons, so he made a will: "Give it to the third 1/2, the second 1/3, and the boss/kloc-. The clever neighbor took one of his big and fat sheep to share with them. Plus this sheep, the old one got nine, the second one got six, and the boss got two. After the three brothers took their sheep away, the neighbors happily took their big and fat sheep home.

2. Easy time: Burmese farmers divide chickens for the king.

There is a poor farmer in Myanmar who hopes to get rich one day. One day, he presented a rooster to the king.

The king smiled and said, "A rooster is a trivial gift to me. There are six people in my family: me, the queen, my two sons and two daughters. How to divide this rooster? "

The farmer cut off the head of the chicken and presented it to the king, saying, "Your Majesty is the head of state. Please accept this generous gift of the head of the chicken." Then he cut the meat off the chicken's back and said, "This is for the queen-the queen bears the burden of the whole family." He cut off two chicken feet and said, "These are only for two princes. They will follow in your footsteps and ascend to the throne of the ruler. "

Then he cut off two wings and said, "Let the two princesses get one wing each, because when they get married one day, they will fly away with her husband. The rest belongs to me, because I am your majesty's guest, and the host has the obligation to entertain the guests with the best food. "

The king was very satisfied with the farmer's witty answer and gave him a lot of gold, silver and precious stones. A greedy man, after learning the story of the farmer getting rich, came to the palace with five cocks and said to the king, "I offer five cocks to pay my respects to your majesty."

The king saw the man's purpose at a glance and said, "I'm happy to accept your five cocks, but there are six people in my family." If you can share them with us fairly and reasonably, I will reward you greatly. " Greedy men don't know how to distribute. He regretted that he should bring six cocks instead of five.

The king sent for the farmer to share.

The farmer said calmly, "Your Majesty, this is easy to handle: one rooster is dedicated to your Majesty and Queen, the other one is dedicated to two princes, and the third one belongs to two princesses. The remaining two cocks are my own, because I am your majesty's guest. This is the only reasonable way to allocate roosters, because your majesty, the queen and another rooster add up to three, your majesty's two princes and a rooster add up to three, your majesty's two princesses and a rooster add up to three, and I and the remaining two roosters add up to three. " The king was very satisfied. He rewarded the farmer with two cocks and gave him a large reward. But greedy people return empty-handed and disappointed.
