Chapter 42
"Count, why not? Continue to take it out, which is a topic we have studied for so long!" Pei Dong said gnashing his teeth: "after all these topics are said, we will take out the controversial topic handed down from ancient times!"
"Good!" Wu Changhui thought it was of little use, but Pei Donglai ordered so, so he could only continue.
They prepared a total of seven questions, including the controversial one.
It is conceivable that the following five questions do not need Li Muyun. The people of Yanghua academy behind her can solve them by using the methods given by Li Muyun. Even those literati who are interested in mathematics can solve them.
Everyone's face was beaming, as if he had picked up the baby. Pei Donglai's face was darker, but there was still a faint smile on the corner of his mouth. In addition to those close to him knowing that he was in a bad mood, other outsiders thought he was still indifferent and elegant.
"Changhui, you take out that question."
"Yes!"
"A general took 1500 soldiers to war and killed four or five hundred people. Standing in a row of three, there were two more people; standing in a row of five, there were four more people; standing in a row of seven, there were six more people. How many people were there?"
As soon as this problem was solved, everyone calmed down. This problem is a famous and controversial one. Everyone has studied it and can't solve it. The people of Peimen academy actually embarrassed Yanghua Academy with this question. The people of Yanghua academy will lose this time.
Li Muyun didn't care. She solved it anyway.
It means three people count, and the rest * 70. Five people, the rest * 21. One for seven, the rest * 15. Then add + 105. You'll know if you feel right. Because four or five hundred people are known to be dead.
So the algorithm is like this: 2 * 70 + 4 * 21 + 6 * 15 = 314 people
314 + 105 + 105 + 105 + 105 + 105 + 105 = 1049 persons. Because four or five hundred people are known to have died.
When she solves the problem.
The people around her looked at her with admiration. He solved the controversial problem of numeracy handed down from ancient times. How powerful is he?
"Great, childe Li, I knew you would win Yanghua academy!" Shen Jianlin was very excited and put his arm around Li Muyun's shoulder and put it on her shoulder. His face was full of excitement: "wait, let's go to Yixiang garden to celebrate." he announced to the people behind him.
"Great." the people of Yanghua academy clapped their hands excitedly. Everyone's face was very ruddy and excited. They were poor and had no chance to go to Yixiang garden, but where Shen Jianlin took them to celebrate was a great blessing for them.
Li Muyun's shoulder sank. She quickly put Shen Jianlin's hand down: "childe Shen, you learn martial arts. I don't learn martial arts. I can't bear your strength."
"Ha ha, I'm so excited." Shen Jianlin glanced at Li Muyun's body, which is really too weak.
"Just pay attention next time." the little brother who recommended himself really didn't know the importance.
It was Yanghua Academy's turn to write a question. The people of Yanghua academy didn't write a question. They only asked Li Muyun to write a question. She didn't refuse, and directly said, "there's only one question for me."
"There are 190 iron sheets to make boxes. Each iron sheet makes 8 box bodies or 22 box bottoms. One box body and two box bottoms form a complete box. How many iron sheets to make box bodies and box bottoms can be used to make a batch of complete boxes?"
This problem is a binary linear equation, which is also the knowledge of junior middle school and senior high school, but for the ancients, they won't be lucky. Li Muyun thinks it can embarrass them.
As she thought, the time for incense is over. The people of Peimen academy and the people around them didn't solve this problem.
"Mr. Li, you can't solve this problem yourself?" Peidong asked.
Li Muyun smiled: "in fact, this problem is solved in this way,
Set X pieces as box body,
Y sheets as the bottom of the box,
There are 8x boxes,
22y at the bottom of the box
x+y=190 8x=22y/2
The solution is x = 110, y = 80
That is, 110 for the box body and 80 for the box bottom. "
The people lowered their heads again. According to Li Muyun's calculation idea, they thought it was very simple. It was similar to those algorithms just now. Just now they assumed one number, and now they assumed two numbers. If these numbers were counted into it, they could really solve the results.
All the people present were smart people. Li Muyun never thought that ancient people were more stupid than modern people, but modern people contacted and saw more, and stood on the shoulders of giants, so they knew more about nature than ancient people.
It's cheating to crush others.
The people of Yanghua academy won. Shen Jianlin jumped up and down excitedly and shouted, "we won, we won." he gave everyone in Yanghua academy a hug.
Those who were hugged by him took a pathetic step back, and then touched their chest
When he wanted to hug Li Muyun, Li Muyun quickly sidled away. Nonsense, his strength was so great that he was held by a bear. Can he stand it?
In particular, Shen Jianlin, a little fat man, has great strength. After those people were hugged by him, they all looked hoarse and grinned, so she wouldn't be wronged.
Shen Jianlin was too happy. He didn't care about Li Muyun's dislike of himself. With a smile on his face, he jumped up excitedly with his surrounding partners and told the process of winning.
The people of Peimen academy lost this time. They lowered their heads and prepared to leave. Li Muyun hurriedly stepped forward and came to Peidong: "young master Pei, what's the bet this time? You haven't forgotten your agreement with me?"
Pei Donglai's face became more smelly. He turned his head and ordered Mo Chong to say, "go and bring the red gold Maitreya Buddha to fourth Master Li." after that, he squeezed out an ugly smile to Li Muyun: "fourth Master Li, I have something else to do. I'll go first." although he lost, his demeanor can't lose.
"Then, young master Pei, go slowly!" Li Muyun came to Peidong, stretched out his right hand, and compared a pair of scissors to him, winning the second junior again.
Pei Donglai's face sank. This Li Muyun insulted himself with gestures again. Hum. He left in a hurry.
When Mo Chong brought the red gold Maitreya, Li Muyun looked carefully. There was nothing special. Is this Maitreya from Duan Rongting's family... What remains? Will cause Duan Rongting to lose his attitude when he sees it?
She touched and knocked. She couldn't see any problem at once. Maybe Shen could see it? She ordered Duan Rongting to say, "cut off the water. Take this red gold Maitreya Buddha back to my mother. Since it is my father's relic, let my mother take it."
"Good!" Wu Changhui thought it was of little use, but Pei Donglai ordered so, so he could only continue.
They prepared a total of seven questions, including the controversial one.
It is conceivable that the following five questions do not need Li Muyun. The people of Yanghua academy behind her can solve them by using the methods given by Li Muyun. Even those literati who are interested in mathematics can solve them.
