They Have a System in Daqin

Chapter 132 Mr. Changping’s question

In the following time, Mr. Changping also left and talked about it, and Jiang Ziyi also chatted with Mr. Changping.

I have to say that Mr. Changping is still very good at talking. Even if the two have never known each other before, Mr. Changping can always find some topics to discuss with Jiang Ziyi.

It’s just that Jiang Ziyi didn’t figure out the purpose of Lord Changping.

However, Jiang Ziyi didn’t care, just as Mr. Changping was giving himself a good signal.

Don’t worry, Jiang Ziyi is also at ease talking nonsense to Mr. Changping.

Really speaking, Jiang Ziyi, a ‘modern man’, will not lose to Changping Jun, an ancient man.

“I heard that Mr. Ziyi is knowledgeable and talented. Today, Xiong Qi has a question. Ask Mr. Ziyi. I hope Mr. Ziyi can help Xiong Qi.” Mr. Changping smiled slightly and seemed to have finally entered the topic.

“I would like to hear the details, Zi Yi must know everything.” Jiang Ziyi said lightly.

Even if Jiang Ziyi couldn’t answer, there would be no loss.

Mr. Changping nodded, and then said, “Mr. Ziyi, please advise. Today, there are chickens and rabbits in the same cage. There are 30 heads on the top and one hundred feet underneath them. What is the size of the chickens and rabbits?”

Hearing Mr. Changping’s question, Jiang Ziyi was stunned, with 10,000 beasts and horses floating in his heart.

Mr. Changping’s question is very simple in translation: There are several chickens and rabbits in the same cage, counting from the top, there are thirty heads, and counting from the bottom, there are a hundred feet.

How many chickens and rabbits are there in the cage?

Isn’t this the most basic problem of chicken and rabbit in the same cage when elementary school students learn XY equations?

In Jiang Ziyi’s previous life, let alone junior high school students, even elementary school students in the fifth grade could answer…

On the contrary, some older middle-aged people may forget how to do it because they have not been exposed to these things for a long time.

How could Lord Changping ask this kind of question?

Jiang Ziyi thought that Lord Changping would ask about his views on Yingzheng and so on.

This is also Jiang Ziyi thinking too much. It is only the first time Changping Jun has met Jiang Ziyi. He doesn’t know Jiang Ziyi yet, so why would he ask sensitive questions about Yingzheng?

Seeing Jiang Ziyi was stunned, a trace of pride flashed in Chang Ping Jun’s heart.

Just now Mr. Changping chatted with Jiang Ziyi. Mr. Changping really saw Jiang Ziyi’s knowledgeable and talented people. No matter what he was talking about, Jiang Ziyi always had his own set of opinions.(Read more @ wuxiax.com)

Moreover, even Mr. Changping had to accept these opinions.

It was precisely because of this that Jun Changping saw Lie Xinxi and asked the question he heard from his niece.

In the world of Qin Shi, the study of mathematics can be said to be in its infancy stage, so such topics are particularly difficult.

“Mr. Ziyi don’t need to worry. This topic is a question that came up with his niece playing around. It took three days for Xiong Qibucai to come up with the answer. After Xiong Qi leaves, Mr. Ziyi can continue. thinking.”

Before Changping finished speaking, Jiang Ziyi interrupted him: “Don’t think about it, I already have the answer.”

“Mr. Ziyi is not more impatient, take your time…what? Mr. Ziyi, you already have the answer.”

Jun Changping was drinking tea, and after hearing Jiang Ziyi’s words, he almost threw the teacup out.

His eyes widened, looking at Jiang Ziyi, his eyes were full of disbelief.

After a while, Lord Changping seemed to have thought of something, and said vaguely: “Mr. Ziyi, this question is very difficult. Even if you can’t figure it out for a while, you don’t need to…”

There was a helpless look on Jiang Ziyi’s face. With such a simple subject, Jiang Ziyi would know it as long as he thought about it, but he didn’t expect Changping Jun not to believe it and thought he was trying to do it.

“Ten chickens and 20 rabbits, right?” Jiang Ziyi looked at Changping Jun like a fool, and Chang Ping looked at Jiang Ziyi like a god. I’m sorry.

Hearing Jiang Ziyi directly said the correct answer, Lord Changping seemed to have seen a ghost: “How did Mr. Ziyi do it?” Could it be that he had seen this question before?

Of course, Mr. Changping did not say the following sentence directly.

The corners of Jiang Ziyi’s mouth raised slightly, wondering why there was a feeling of crushing IQ.

However, this feeling was only a passing moment. After all, Qin Shi’s people didn’t have much research on arithmetic, so there was such a problem.

“There should be a lot of liberation for this question.”

“The first solution is to assume that the cage is full of chickens, then there should be thirty heads and sixty feet.”

“But there are actually a hundred feet, and each rabbit happens to have two more feet than a chicken. The extra 40 feet correspond to 20 rabbits, and 30 heads minus 20 rabbit heads. , The remaining ten are chickens.”

While Jiang Ziyi was talking, he took out paper and pen and wrote down.

(100-2×30)/2 is a rabbit

30-(100-2×30)/2 is chicken

Hearing Jiang Ziyi’s words, Jun Changping nodded.

This method was a method he thought of for three days before he came up with a reminder from his niece.

But how do you look at these calculations? What does it mean?

And listening to Jiang Ziyi’s meaning, does he have other ways?

“Of course, assuming that the cage is full of rabbits, then there are 120 feet, and the extra 20 feet correspond to exactly 10 chickens.”

“This is the second algorithm.”

(30×4-100)/2 is chicken

30-(30×4-100)/2 is a rabbit.

This algorithm is similar to the first one, and Mr. Changping quickly understood it.

“This algorithm is no different from the first one. It can only be regarded as the same method.” As if to save face, Mr. Changping said.

Jiang Ziyi smiled, but didn’t care.

stubborn? Are you still stubborn?

Want to trouble me with such a problem? I want to answer your doubts about life.

“That’s the same method, then now, it’s the second method!”

Jiang Ziyi did not entangle, and wrote the second method directly on the paper.

“The second method……”
