"Okay, that's all for the question. In addition, in order to reduce the difficulty of answering the questions, I will also make a few hints. ”

After writing this question, Tao Li turned sideways to look at everyone, then turned to the blackboard again, and said as he wrote:

"1. The five prisoners were very intelligent people.

2. Their principle is to save their lives first, and then kill as many people as they can.

3. It is not necessary to divide all the 100 soybeans, but make sure that everyone catches at least one.

4. If there is a duplicate number of soybeans caught by the prisoner, then it is also considered the largest and the smallest, and they will be executed together. ”

After giving all the conditions, the corner of Tao Li's mouth showed a smile that was imperceptible to ordinary people, "Okay, now everyone can answer."

I hope that in fifteen minutes, someone will be able to give me a complete answer. ”

After saying this, Tao Li walked back to the front of the podium, pulled a chair and sat down, and read the book leisurely, no longer caring about the reaction of the students sitting below.

Everyone hopes that they can make this problem in the first time, so that they can not only win the teacher's appreciation, but also show their skills in front of all the students who participate in the competition.

However, it didn't take long for the students in the lecture hall to find that the question on the blackboard did not seem to be as simple as it seemed, and it was even much more difficult than they imagined!

Because looking at this question, they don't have any ideas to speak of!

Looking at the question, although there is a lot of descriptive text in the question stem, they found only two of the really valuable, or key parts of the stem: 5 prisoners and 100 soybeans.

For them, who are accustomed to seeing a lot of valuable numbers when doing questions, there are only two numerical conditions for such a big question, which makes them feel at a loss for a while.

Although in mathematics competitions, there will be a lot of problems with similar stem conditions, but those problems can generally know which theorem to use at a glance to solve, even if you can't do it in a short time, knowing which theorem to use is also helpful for the solution of subsequent problems.

However, the question in front of me is completely beyond the scope of the students present. More than three minutes have passed since Tao Li wrote this question, and most of them have read the question no less than five times, and they can even memorize it, but they don't know where to start.

In the exam, there is generally such a rule, that is, the calculation of complicated questions will not be too difficult, and the difficult questions are generally very simple. And the question they are facing at this moment obviously belongs to the latter.

It's not just ordinary competition candidates who have such doubts, but even real math students like Zheng Tongya, Shen Lei and Zhang Xingchen feel at a loss.

At this moment, the table in front of Zheng Tongya was already full of a piece of scratch paper, A4-sized paper, and both sides were densely written with his first attempt to solve the problem. And now the scratch paper in his hand is about to run out on the first side, but despite this, Zheng Tongya still can't come up with a final answer.

Since he went to high school, this is the first time Zheng Tongya has encountered this kind of topic that he can't start, even if he has been a previous CMO or even an IMO topic, he has never encountered such a situation!

Zheng Tongya frowned, the pen in his hand sometimes wrote something on the paper quickly, and sometimes stopped, holding the pen in his right hand and turning quickly, and his brain's thinking was also running at high speed with the pen, just like a high-performance supercomputer.

Shen Lei, who was sitting next to him, was no better, unlike Zheng Tongya, when Shen Lei was doing questions, he liked to think more first, and only after getting ideas would he start writing to answer, rather than like Zheng Tongya like to make all kinds of attempts on scratch paper.

Generally speaking, at this time, Shen Lei's scratch paper should at least have a preliminary solution formula on a topic, but at this moment, the scratch paper in front of him is blank and empty!

Of course, the reason for this situation, in addition to the difficulty of the question itself, is also partly because of the environment, Tao Li requires that this question be made within 15 minutes, and the whole classroom is also full of competitors, in such a tense atmosphere, either the potential of the brain is stimulated, the more courageous the battle, and quickly win the question, or because of the nervousness and disrupted the answering ideas.

For many, the latter accounts for a significantly larger proportion.

"Brother Ya, how are you doing over there, do you have any ideas?" Shen Lei asked as he pondered.

The two of them are recognized as the most talented students in mathematics in Jinling Middle School in recent years, a little Gauss, a little prince, although Zheng Tongya is a senior brother, Shen Lei also respects him, but in his heart, it is estimated that both of them want to be able to overpower each other.

Healthy competition, this is what Chen Tianxiang is willing to see and has always admired, with comparable competitors, there will be pressure, and with pressure, will continue to forge ahead, and will not stop.

"Not yet, I've tried a lot of things, but I still don't think it works. What about you?" Zheng Tongya shook his head with a wry smile, he felt that he was about to lose his mind.

"I didn't have a good idea, and I didn't know which theorem to use to solve it after thinking about it for a long time. Shen Lei also shook his head and replied softly.

"Then if you take a look at the few methods I've tried, maybe it will inspire you. With that, Zheng Tongya directly handed the two pieces of scratch paper he had used to Shen Lei.

Shen Lei was not polite, took the scratch paper, and began to read it seriously. It's just that in less than a minute, Shen Lei handed the scratch paper back again, and then shook his head again, "I still don't have a clue." ”

Shen Lei had also thought about these methods used by Zheng Tongya, but he had already overturned them before he started writing, so just looking at Zheng Tongya's scratch paper could not bring him new ideas.

"Hey, Xingchen, you seem to have some ideas!" Zheng Tongya inadvertently caught a glimpse of Zhang Xingchen, who was across the seat from him, as if he had been answering silently, and there was a faint excitement between his eyebrows, so he couldn't help but ask.

Could it be that the topic that he and Shen Lei had no ideas for was actually made by Zhang Xingchen?
