When Gao Lan saw this question on the test paper, she couldn't help taking a breath.

Don't dare to spit it out.

She was curious and wanted to see how Qin Chen would solve this problem.

"For a road, team A needs 24 days to complete the repair alone, and team B needs 30 days to complete the repair alone. After a few days of cooperation between team A and team B, team B stopped to rest, and team A continued to repair it for six days."

After reading the topic, Qin Chen didn't even think about it, so he wrote directly.

Qin Chen uses the method of setting the unknown number X.

Suppose A and B have been repaired for X days.

It is known that it takes 24 days for A to repair this road alone, so A's efficiency is 1/24.

And it takes 30 days for B to repair it alone, so B’s efficiency is 1/30.

Add these two numbers together and multiply by X.

Then add the distance covered in the six days after A, which is six times 1/24.

Because of this problem, Qin Chen assumes that the total distance is unit 1.

Then this equation is listed as 1/24+1/30)X+6X1/24=1."

Connecting to this equation, X is equal to nine days.

Seeing this process written by Qin Chen, Gao Lan was completely stupid.

She would never have thought that Qin Chen, a sophomore Chinese undergraduate, could actually do such a rare test question.

You know, this kind of topic can't be done by graduate students.

At least Gao Lan would not think of this solution for a while.

Although she has also studied mathematics as a graduate student, she compares it with Qin Chen in this way.

It's too far.

Now, Gao Lan somewhat believes what the former math teacher Zhao Dabao said.

Zhao Dabao said that Qin Chen was a genius in mathematics, and at that time he brought Qin Chen the postgraduate examination papers.

Qin Chen finished all the thick test papers in less than ten minutes.

At that time, Gao Lan thought that Qin Chen had seen this kind of topic before.

In other words, Qin Chen had some talents in mathematics, but she hadn't discovered it before.

But now it seems that Qin Chen has more than a little mathematics talent, that is simply an outstanding enchanting player.

If Qin Chen has only a little talent in mathematics.

Then those so-called mathematics professors and doctoral students majoring in mathematics are just rubbish.

Just when Gao Lan was shocked here, she found Qin Chen moved again.

This time Qin Chen didn't do the next question, but wrote the second solution under this question.

Gao Lan didn't take it seriously at first, but after reading the problem solving process written by Qin Chen.

Gao Lan was shocked, and almost pulled it past without coming up.

I saw Qin Chen wrote in the second method 1-6x1/24)/(1/24+1/30)=10."

Qin Chen simply wrote such a calculation, and then the answer was nine.

At first, Gao Lan still couldn't understand this test question.

After a long pause, Gao Lan found out, isn't this stepping on a horse?

If someone told Gao Lan before that there are mathematics geniuses in this world, they can learn by themselves without learning.

Gao Lan would definitely call this man a lunatic and crazy.

Although mathematics is only a basic subject, it is the foundation of all learning.

It's like physicalization. If you leave the mathematical calculation method, it will not go on at all.

There are also liberal arts involved, such as geography and biology, which also has a lot of calculation content.

For example, what is the tropic of the equator, or biological DNA.

All these things need to be applied to mathematics.

Therefore, although the science of mathematics is only a basic subject, it is difficult to master.

It is impossible for ordinary people to study with great concentration for decades.

Even a genius in mathematics can spend a lot of hard work to make a prominence in mathematics.

But now, Qin Chen completely broke this natural law.

Because as far as Gao Lan knew, Qin Chen never listened to lectures in class.

Either sleep and play games, or skip class and go to Internet cafes.

A while ago, before the entrance exam, Gao Lan also saw Qin Chen go to the Internet cafe to book overnight.

But it's such a foolish student who doesn't want to study.

Now that he has solved a math problem that even graduate students can't solve, how can Gao Lan not be shocked?

After Qin Chen checked the calculations, he also noticed that Gao Lan was standing next to him.

So Qin Chen stopped writing.

Now that there is still an hour before the exam, Qin Chen intends to get some sleep, and then he will hand in the papers in advance to eat.

Seeing that Qin Chen stopped moving, Gao Lan couldn't help but remind Qin Chen intentionally.

You just finished the second answer, why didn't you do it?

"Don't you know how to do the following topics?"

But it's impossible to think about it.

Like the previous two difficult math problems, Qin Chen solved it with frowned eyebrows.

Even if the following topics are somewhat difficult, I am afraid that Qin Chen will not be too difficult for them.

"Qin Chen, you...?" Gao Lan swallowed when he reached her lips.

Because she saw Qin Chen flip through the test papers and put back the test papers he had previously taken from the corner of the table.

Then, he revealed his own test paper underneath.

Gao Lan read clearly, Qin Chen's own two test papers.

That is, the joint examination papers for undergraduate and postgraduate examinations are all written densely at this time, and they are all done!

Seeing this scene, Gao Lan was once again caught in the circle.

Feelings What Qin Chen did just now was not his own business.

It's just being idle and bored, taking the test papers of candidates that others have abandoned the exam to do?

Even other people's test papers can make this wonderful calculation.

Gao Lan couldn't think of what kind of curious solutions Qin Chen could write on his own test paper.

But since Qin Chen can do it, why not let him do all the blank test papers?

This time the city's college students' joint entrance exam, the examination papers of all subjects are unprecedentedly difficult.

Forget other subjects.

Like the language, English, this kind of purely Mongolian words can still get a little score.

But in mathematics, candidates are simply not covered by it.

This trick is useless for mathematics, because most of the objective math problems are.

An objective question is not like a subjective question, it is what it should be.

Even if there is a difference of one number, one decimal point is wrong!

Therefore, UU reading www.uukanshu. The mathematics of the previous com entrance exams is a subject that draws points.

If there are students who can do mathematics, take more scores.

So maybe it can improve Jinling University's undergraduate entrance exam scores as a whole?

Gao Lan thought, "I am also a member of Jinling University. If Jinling University is banned because of the bottom, then what should I do?"

Gao Lan was trained by Jinling University.

University, graduate students, and Gao Lan all spent time at Jinling University.

After graduating from Jinling University, Gao Lan resolutely chose to stay as a teacher.

If Jinling University was banned by the Education Department at that time, then her job could not be kept?

If so...

Gao Lan thoughtfully, the Civic was constantly circulating, thinking about something.

Only a few seconds...
