It is said that Tang Priest and his disciples came to guo jia cun after learning Buddhist scriptures in the West, and were warmly welcomed by the villagers. Everyone regards them as heroes of exorcism, not only taking photos with them as a souvenir, but also inviting them to be guests at home.

Facing the hospitality of the villagers, the teachers and apprentices felt very sorry, and helped them harvest crops, plow fields and rake fields whenever they had the chance. In the first few days, the pig worked hard, but after a few days, he became lazy again. He thinks it's too hard to work like this, and the master is more comfortable. As long as you sit and preach and recite Buddha, you will have everything. In fact, the master is nothing. If it weren't for the Monkey King's critical eye and skill, I'm afraid I couldn't even go to the Western Heaven, let alone learn from the Buddhist scriptures. If I have such an apprentice, I can do something, and then, haha, I can enjoy my retirement.

So Bajie began to talk. Within a few days, he recruited nine apprentices, and he named them: Xiao Yi Huan, Xiao Er Huan ... Xiao Jiu Huan. It stands to reason that Bajie should concentrate on practicing and teaching his disciples now. However, he still did not change his bad habits, and often took his disciples out to eat and drink, which made the people complain. People are thinking about the good things they have done for everyone, and no one is embarrassed to complain to Wukong. In this way, Bajie people are even more fearless, eating five or six hundred steamed buns at a time, and the people are almost boiling.

There is a girl named Ganoderma lucidum in the neighboring village. She is clever and kind, and often uses her wisdom to fight the wicked skillfully. Hearing this, she decided to punish Bajie. When she came to guo jia cun to open a restaurant, Bajie heard the news. Lingzhi girl pretended to be surprised and said, "Master Wuneng, it's a great honor for you to come to my restaurant. Come to my place for dinner in the future and don't go anywhere else. " She paused and said, "Here is a round table specially prepared for you. You ten people sit in a different order every time. When you complete all the orders, I will provide you with meals for free. But before that, every time you eat a meal, you should do a good deed for a villager in the village. What do you think? " Hearing this tempting suggestion, Bajie was so excited that they repeatedly said yes. So they always eat according to the agreed conditions and write down the seats. A few years later, new orders are still emerging, and Bajie is puzzled and has to ask Wukong for advice. Wukong couldn't help laughing when he heard this. "You idiot, you can't calculate such a simple account, and you still want to take advantage of it. You'll never get this free meal. " "Can't we get it after twenty or thirty years?" Wukong said, "Then I'll work out this account for you. Let's start with a simple number. Suppose there are three people eating. We gave them the serial numbers of 1, 2, 3, and there were six sequences, namely 123, 132, 2 13, 23 1 3 12, 3265433. If four people eat a piece of metal, the first person will sit still, and the seats of the other three people will change six times. When four people sit still as the first person in turn, the overall arrangement order is 6× 4 = 24. According to the same method, it can be inferred that if five people go to eat, there will be 24× 5 = 120 arrangements ... 10 people will have 3628800 different arrangements. Because you have to eat three meals a day, you can calculate the number of days to eat with 3628800÷3: 1209600 days, which is nearly 3320 years. Think about it, can this free leek be eaten? "

After Wukong's calculation, Bajie suddenly understood the intention of Ganoderma lucidum girl and couldn't help feeling ashamed. From then on, Bajie often took his migrant brother to help the villagers. They regained people's love.

Countermeasures to win

During the Warring States Period, Qi Weiwang and Tian Ji raced, and Qi Weiwang and Tian Ji each had three good horses: getting on, winning and dismounting. The race is divided into three times, and thousands of dollars are bet on each horse race. Because the horsepower of the two horses is almost the same, and Qi Weiwang's horse is better than Tian Ji's, most people think that Tian Ji will lose. However, Tian Ji took the advice of his disciple Sun Bin (a famous strategist) and dismounted Qi Weiwang, Ma Zhong of Qi Weiwang and Qi Weiwang. As a result, Tian Ji beat Qi Weiwang 2-/kloc-0-and got a daughter. This is an example of China's ancient substitution game theory to solve problems.

Here is a game played by two people: take turns to report numbers, and the number reported cannot exceed 8 (nor can it be 0). Add up the figures reported by two people, and whoever reports more figures will win if the total is 88. If you were allowed to count first, how many times should you count first to win?

Analysis: Because everyone reports at least 1 and at most 8 at a time, someone reports and another person will find a number, so the sum of this number and a reported number is 9. According to the rules, whoever counts and makes the sum 88 wins, so it can be inferred that whoever counts and makes the sum 79 (= 88-9) wins. 88 = 9× 9+7, and so on. Whoever counts 16 wins. Furthermore, whoever reports 7 first will win. Therefore, the winning strategy of the first whistleblower is: report 7 first, and then if the other party reports K( 1≤K≤8), you report (9-K). In this way, you will win if you quote 10.

When does the snail climb up the well?

A snail accidentally fell into a dry well. It lay at the bottom of the well and began to cry. Mass (

Lai) Toad crawled over and whispered to the snail, "Don't cry, little brother! It's no use crying. The shaft wall is too high. If you fall here, you can only live here. I have been here for many years, and I haven't seen the sun for a long time, let alone want to eat swan meat! " The snail looked at the old and ugly toad and thought, "What a beautiful world outside the well! I can never live in a dark and cold well like it! " The snail said to the toad, "Uncle toad, I can't live here. I have to climb up! "! How deep is this well? ""Ha ha ha ..., are you kidding! The depth of this well is10m. How can you climb up with such a heavy shell at a young age? " "I am not afraid of suffering, not afraid of being tired. I can always climb out after a while every day! " The next day, the snail ate and drank enough and began to climb the wall. It kept climbing and finally climbed 5 meters at night. The snail was very happy and thought, "At this rate, I can climb up tomorrow night." Thinking about it, it fell asleep unconsciously. In the morning, the snail was awakened by a purr. At first glance, it turned out that Uncle Tu was still sleeping. It was surprised: "How come I am so close to the bottom of the well?" It turned out that this snail slipped 4 meters from the borehole wall after falling asleep. The snail sighed, gritted his teeth and began to climb again. At night, it climbed another 5 meters, but at night the snail slipped another 4 meters. Climb and climb, and finally the strong snail climbed up the well platform. Children, can you guess how many days it will take a snail to climb the drilling platform?

Water quantity problem

Imagine you drink coke from a bottle. If you want to keep half a bottle of coke in the bottle, a simple way is to drink the liquid level in the inclined bottle to the intersection of the bottom and the edge of the bottle.

Here is a similar problem solved by different programs. Irregular transparent glass bottle, strong acid. There are only two signs on the bottle, the high one is 10 liter, and the low one is 5 liters.

Someone used a small amount of acid, and the amount was unknown, which made the acid ratio in the bottle slightly lower than 10 liter. You must pour 5 liters of acid from the bottle to do the experiment. This acid is dangerous and volatile, so it can't be poured into other containers. So is there any simple way to pour out the exact amount?

The clever way is to put some small glass stones in the bottle until the acid reaches the high standard, and then just pour out the acid until it reaches the low standard.

Hippo puzzle

A many years ago, the leader of a certain tribe respected the sacred hippo very much.

B Every year on the leader's birthday, the leader and his tax collector will take the hippo to the tax collection station by royal barge.

There is a local custom to give the leader gold coins equivalent to the weight of the sacred hippo. The tax collection station is also huge, with hippos and gold coins at the same time.

D. The leader fed the hippo too well. The hippo was too heavy and the balance beam was broken. It only takes a few days to repair the scale.

E. The leader is very angry. He told the tax collector.

Chief: I want to get my gold coin today, and it must be accurate. If you can't weigh out the gold coins before sunset, I'll cut your head off.

F. The poor tax collector was too scared to think.

G. after several hours of thinking, he suddenly had a good idea. Can you guess what this idea is?

H. the idea is really simple. The tax collector put the hippo on the boat and recorded the waterline of the boat.

Then he took the hippo away from the boat and put the gold coins on the boat. When the same waterline is reached, the weight of gold coins on board is equivalent to that of hippopotamus.

Mathematical jokes

Occupational characteristics

Three scientists went to Scotland from London to attend a conference. Soon after crossing the border, they found a black sheep.

"This is very interesting," said the astronomer. "All sheep in Scotland are black."

"This inference is unreliable," replied the physicist. "We can only conclude that some sheep in Scotland are black."

The logician immediately went on to say, "What we really know is that there is at least one black sheep in at least one place in Scotland."

Number of life and death

The English poet Jannison wrote a poem, several lines of which read: "Every minute, a person is dying, and every minute, a person is born ..."

After reading it, a mathematician wrote to question it. The letter said: "dear sir, reading famous books makes people feel fast, but there are a few illogical lines, which is really difficult to agree." According to your algorithm, the number of life and death per minute is balanced, and the number of people on the earth is eternal. But you know, in fact, the population on the earth is growing. To be exact, 1.6749 people are born every minute, which is quite different from the number you provided in your poem. For the sake of practicality, if you don't object, I suggest you use a score of 7/6, that is, change the poem to: "Every minute, one person dies, and every minute, one and a sixth people are born ..."
