The first question above the national referendum surprised everyone, and many people broke down emotionally.

Fang Chao was unwilling to give up this question, it was his idea to march to the second game tomorrow, of course, he had to get a full score in the first game, otherwise, he would be ashamed of the system.

The system did not propose any punishment for this national final, so you can imagine how merciful it was to him.

Fang Chao couldn't let the system down.

At the same time, I also want to improve my math level in such a competition.

Only if he gets a perfect score in both races can he become the champion of the CMO national finals and thus get a higher score.

Only in the case of the championship foundation, he can get the Xueba points given by the system, which is the stage of national mathematics and represents the highest level of mathematics in China.

He began to re-examine the question, not missing a single detail.

This is a logical reasoning problem, but it is also within the scope of mathematics, which is all-encompassing, and logical reasoning calculus is also among them.

And such a question is actually similar to Sudoku.

It also needs to be disassembled, distinguished, and then assembled.

Probability, then union and intersection.

When he kept these eighteen prompts in his heart, ten minutes later, Fang Chao began to write.

According to the three pieces of information 15, 4, and 16, it can be concluded that the first room on the left, Beijingers, drinks Moutai.

Establish this conclusion as Conclusion A.

This kind of data is actually not easy to remember, because there are several people who smoke, or smoke different cigarettes, and then the color of the room will also give people a misleading, which comes from the fault in the memory method, because too many things to remember, it is often easy to completely confuse these memories, once one of the memory points is confused with other memory points, then no matter how much time you waste on this problem, the final result will be very different.

Fang Chao's memory points are different from others, he may not be particularly strong, but in terms of memory, he has a unique advantage, this is the ability given to Fang Chao by the system, others can't imitate it, or people who are born with talent in this area can also be half like this.

From 11 to 18, the order from left to right can be obtained: Hilton, Marlboro, 666

The conclusion reached here is set up as Conclusion B.

According to 14, 15, and conclusion B, the next clue is drawn.

The order of cigarette smoking is from left to right: Jianpai, Hilton, Marlboro, 666, Hongtashan

This conclusion is C.

Conclusion from 5 D: The first room on the left: Pekingese, drinking Moutai, smoking Jian brand cigarettes, raising horses

From 1 and 2, it is concluded that E: the first room on the left is not yellow, red (blue on the left), white (red and blue on the left)

Then from 7, D, and E, it is concluded that F: the first room on the left: Pekingese, blue, raising horses, smoking Jian brand cigarettes, drinking Moutai

Based on 6, 17, 3, and 16, we conclude that G: The first room on the left: I love one of beef and tofu

Look, is this still a simple math problem? Even if Fang Chao has the level of mathematics LV3, he is sweating profusely when facing this problem, obviously there are fans on in the room, but it is hot...... Because of the wholehearted dedication, the blood flow in the body accelerated, and because of the influence of tension and anxiety, I fell into an extremely stuffy state.

At this time, if there is a pond in front of you, I believe that 80% of the candidates want to plunge into the pond to cool down, but dare not plunge into it, it is a girl...... How can I take the exam if my clothes get wet?

Many test takers have not even started writing yet, but they are trapped in the cage of this first question.

The first question in the first national final does not involve many mathematics majors, but it is such a question that makes it difficult for most candidates.

It took Fang Chao more than forty minutes to reach the conclusion from A to G, and his cheeks were covered with sweat.

Don't look at the problem he reasoned out is not big, but the brain cells are consumed too quickly.

The teacher who made the question is simply not human, he is the devil, right? He's a demon, right? Where did anyone play like that......

It's almost killing people.

And Director Chen and Director Luo are also quite helpless in the face of such a test paper, they hope that the students they lead will skip the first question first, and start from the second and third questions, so as to increase the probability of passing the candidates on the first day, because even if it is the two of them, they are helpless in the face of this first question, not to mention the students they lead.

Both of them were praying, hoping that Fang Chao would not do the first question first, but must start with the other two questions.

But when they saw that Fang Chao had started from the first question, they immediately collapsed a little.

I said baby, can you have a snack?? This first question is obviously a trap question, it can trap you for as long as it can trap you...... As long as it drags on long enough, then you don't have to think about the next two questions.

But Fang Chao is not two mentors, he is doing the first question to himself.

"If you want to stump me and dream, my favorite thing is to face the difficulties, and the more difficult and troublesome things are, the more I have to do them."

Conclusion from 9 H: The first room on the left: Pekingese, blue, raising horses, smoking Jian brand cigarettes, drinking Moutai, eating tofu

From 13 and 17, it is concluded that the second room on the left: Shanghainese, smoking Hilton, drinking wine, and eating noodles

Conclusion from 8 J: The third room from the left: raising snakes, drinking mineral water, and smoking Marlboro

From 1 and 2, it is concluded that K: pizza lovers live next door to mineral water drinkers

According to 9, it is concluded that L: the fourth room from the left: Tianjin people, red, 666, drinking tea, eating pizza

From 1, 2, 6, and 9, it is concluded that M and N are concluded, respectively.

M: The fifth room from the left: white, Chengdu people, fish farming, smoking Hongta Mountain, drinking beer, eating chicken

N: The third room from the left: yellow, HK people, snake farming, smoking Marlboro, drinking mineral water, eating beef

Conclusion from 7 W: The second room on the left: Green, Shanghainese, raising dogs, smoking Hilton, drinking wine, eating noodles

Then the results are clear.

The first room houses horses, the second room keeps dogs, the third room keeps snakes, and the fifth room keeps fish.

Fang Chao wrote down his steps, and then came to the final conclusion.

Tianjin people who live in the fourth red room on the left, smoke 666, drink tea, and eat pizza have cats.

With such a perfect idea and solution steps, there are almost no mistakes in this problem.

The first question of the first exam of the national final preliminaries scored 21 points, and Fang Chao successfully won it.

With just these 21 points, Fang Chao may successfully pass today's preliminaries, and tomorrow's exam.
