Answers to clever questions

Xu Minghao got closer to Lin Shuran, and when he saw her asking about Xu Mingsong and Xu Mingsheng, he whispered: "Mother, my brothers and Xiao Huzi are still listening to books. I have something to ask you!"

At this time, Xu Junze, Lei Zhanpeng and others also noticed this and looked at Xu Minghao, who was closer to Lin Shuran, his mother.

"What's the matter?" Lin Shuran looked at him and Xu Mingxuan in confusion. What could make the two of them forget about listening to a book.

"Mom, it's like this. The storyteller just said on the stage that there is a clever question in the world that no one can solve. If anyone can solve this question, he will give him the folding fan handed down from his ancestors. Seventh Brother will have already

I want the fan in his hand." Xu Mingxuan said before Xu Minghao could speak.

"It's not easy to get fans. I'll have someone give you a few later!" Lei Zhanpeng and the others heard the conversation clearly. When they heard that Xu Minghao was interested in fans, they smiled and said boldly.

Xu Minghao shook his head and refused. He said that he just wanted the fan in the hand of the storyteller. From the first time he listened to a book in the teahouse, he fell in love with the folding fan that the storyteller often held in his hand. He felt that

Particularly impressive.

Children's preferences are sometimes so weird. Adults think they are ordinary objects, but in their eyes they all have some special meaning. Lin Shuran could understand Xu Minghao's persistence in folding fans, so she smiled and asked him what the clever question was.

So, Xu Minghao told a few people the "clever question" from the storyteller's mouth: "'Today there is a wall ten feet thick, and two rats pass through it. A rat's day is one foot, and a mouse's day is also one foot. A rat's day is doubled.

It’s half a day since the mouse. I asked: When will we meet? How many clothes will each wear?’, Mother, do you know the answer?”

As soon as this question was said, Xu Junze, Lei Zhanpeng, Du Sheng, Qiu Shi, and Lei Yingying all frowned and thought about it. They had never heard of this clever question before, and they thought it was popular among the people.

After hearing this, Lin Shuran's face showed a look of surprise. Why was this title the same as the title in the ancient book "Nine Chapters of Arithmetic" she had read in modern times? Could it be that there is such a book in this time and space?

"This question sounds interesting, but when you think about it, it's actually a bit elusive! Let me do the math with pen and paper!" Du Sheng was very interested after hearing this. He took out pen and paper and started to calculate. He is the number one scholar.

Born in China, I have been smart and eager to learn since I was a child. When I encounter such a clever problem, I naturally want to try to solve it.

""Nine Chapters of Arithmetic"?" Xu Junze, Lei Zhanpeng and Du Sheng all looked at each other. From the confused looks in each other's eyes, it seemed that no one had read this book.

"Mrs. Xu, where is this book now?" Du Sheng has read a lot of poetry and books, but has read very few books on arithmetic. He has never heard of the name "Nine Chapters of Arithmetic". Now he wants to find it.

Take a look.

Suddenly, the crowd watching the performance by the river broke out in commotion and screamed. Immediately afterwards, countless people were squeezed and fell into the cold river. Many people did not know what happened, so they were forced to follow it.

People were crowded together, and the situation was even more serious on the distant bridge filled with people. There was even a stampede. The laughter and laughter just now turned into cries, howls, and screams of helplessness.

"I knew my mother would be able to figure it out!" Xu Minghao's first reaction was that his mother was so powerful. He knew she would be able to figure it out. This answer must be correct, so he remembered the answer after listening to it in a hurry.

After bowing, he quickly ran downstairs. He had to go to the teahouse to get the folding fan that he had been thinking about for a long time.

Du Sheng looked disappointed after hearing this, but he could ask someone to search around. Since Lin Shuran had already read it, there should be more than one book. Thinking of this, he felt relieved again.

Xu Junze and Lei Zhanpeng were not surprised that Lin Shuran had read a book like "Nine Chapters of Arithmetic" that they had never heard of. After all, she was the daughter of a Taifu and the granddaughter of a Bachelor of Arts. She came from a scholarly family.

She will naturally read more books.

Xu Junze and Lei Zhanpeng are not academic masters like Du Sheng, but they are both quick thinkers and talented students. They both tried to solve this problem in their minds, but found that it would take more time.

Soon, the lantern show started on the Qiushui River not far away. Standing on the top floor of the Dengchuan Building, Lin Shuran and the others could see the lantern show intuitively and comprehensively from top to bottom, making the whole performance even more beautiful and spectacular.

There are many people watching the lantern show tonight. There are three floors inside and three floors outside. The rich and powerful people sit in the painting boats on the river and watch closely. Ordinary people gather around the river or stand on the bridge and stretch their necks towards the performance stage.

It seems that during such a major festival, there was no curfew in the Jin Dynasty, and people could have fun all night long.

Du Sheng stared at his pen and smiled awkwardly. He was good at reading and learning, but was a little weak in arithmetic. Then he looked at Lin Shuran curiously and humbly asked for advice: "I wonder how Mrs. Xu calculated the answer to this clever question? Is it possible?

Can you explain it to me?"

Lin Shuran looked at a few people, smiled faintly, and said honestly: "Master Du, you are too polite. In fact, I also read this answer from a book written by a predecessor. The name of the book is "Nine Chapters of Arithmetic".

As for who wrote it, I can’t remember clearly.”

"This -" Lin Shuran seemed a little embarrassed, because she didn't know if this book existed in this time and space, so she had to reply regretfully, "It's really unfortunate. I lost this book after reading it, and now I'm afraid

It can’t be found.”

"Sister Ran, is the answer to this question really like this?" Lei Yingying still didn't believe it. But when she heard the question, she became dizzy and confused. She didn't even understand the answer. Then she turned to her husband Du Sheng

Ask, "Is the answer correct?"

Lei Yingying and Qiu Shi smiled bitterly and shook their heads. They seemed helpless.

As soon as she finished speaking, everyone present looked directly at her, with surprise and confusion in their eyes. Was her casual answer correct?

"On two days, two of seventeenths meet. A rat wears three feet and four inches, which is twelve-seventeenths of an inch. A mouse wears one foot and five inches, which is five-seventeenths of an inch!" At this time, Lin Shuran had already given the answer.

Said it out.

"Stay here and don't move!" There was chaos below. Xu Junze was the first to get up and leave. Before leaving, he told Lin Shuran not to go downstairs.

Lei Zhanpeng and Du Sheng then left with serious faces. Qiu ordered the shopkeeper of Dengchuan Tower not to stop the panicked people from entering the building, but they were not allowed to enter the top floor.

"Brother Hao and the others are still in the teahouse, as well as Brother Chen and the others!" Looking at the people running in panic below, Lin Shuran was first worried about Xu Minghao and Xu Mingchen. Although they were protected by people around them, they would not be able to survive such an emergency.

Due to this situation, there was no guarantee that children like them would not be frightened. She became even more anxious when she thought of this.

"Sister Ran, you can't go down at this time!" Seeing Lin Shuran anxious to go downstairs, Lei Yingying held her arm and said solemnly, "Don't worry, they will be fine. You don't even know how to go downstairs now."

If you can’t get out, look below—”
