Start with a blind date

She had to raise her head by chance, and caught a glimpse of Qin Chen sitting in front of her.

It just so happened that Qin Chen was flipping through the test papers at this time.

On the mathematics paper, there are multiple-choice questions and filling in the blanks on the front, and four big questions on the back.

Qin Chen flipped the scroll at this time, which meant that he had finished filling in the blanks with the previous choices at this moment.

Now start to do the following questions!

Seeing this scene, the corners of Liu Ting's mouth couldn't help twitching.

Because she had just done a few multiple-choice questions, she didn't expect Qin Chen to start answering them!

Qin Chen's act of turning his face also attracted the attention of Director Liu of the Education Department.

This time, the Education Department invited expert groups from various provinces to come up with questions.

Regarding the difficulty of the topic, Officer Liu can be said to be the most understanding.

When he was proctoring Chinese before, he had never seen a classmate like Qin Chen.

"How could you do such a big problem so quickly? Could it be that you did it indiscriminately?" Officer Liu thought to himself.

Yes, it must be so.

This Qin Chen looked foolish, so he must be a scumbag.

You know, this time the Jinling Education Department issued a math problem.

That covered many unsolved mathematical problems in Longguo.

For these problems, even Longguo's mathematics expert group will not be able to come up with answers for a while.

With Qin Chen as a scumbag, how could he do it right?

The more Director Liu thought about it, the more he felt this was the case, and immediately lost interest in Qin Chen.

At this time, there is still more than an hour before the end of the exam.

But there are only a few candidates left in the examination room.

Regarding the few remaining candidates in the examination room, Director Liu felt that except for the female student, the rest were typical scumbags.

Officer Liu couldn't stay any longer, he wanted to visit other examination rooms.

Because this time the Jinling Education Department sent personnel to invigilate the exams in various exam rooms.

These staff members of the Education Department naturally also included the inspecting teachers they sent before.

Now that the Education Department has revoked the visiting teachers, it is inevitable that there will be problems in some examination rooms.

Officer Liu wondered if he should go to other examination rooms and make inspections.

But before leaving, Director Liu still walked up to Liu Ting worriedly.

Director Liu wanted to see how Liu Ting was doing.

If Liu Ting did well in the math test paper, then Director Liu would keep an eye on her next.

She helped other students steal the exam.

Wait until Officer Liu sees Liu Ting's face clearly.

He found that Liu Ting was still doing the first few multiple-choice questions at this time.

I saw the first multiple-choice question "100 monks eat 3 steamed buns, one big monk eats three people, and three young monks eat one. Ask the number of big and small monks. A option is 35 big monks and 65 small monks, b There are 50 senior monks and 50 junior monks in option c, 25 senior monks and 75 junior monks in option c, and 45 senior monks and 55 junior monks in option d.”

Look at Liu Ting's answer again, choose "c"

Director Liu nodded slightly. As a researcher in the mathematics group for many years, he naturally saw that this question was correct.

This is an evolved version of the chicken and rabbit problem.

However, this kind of problem is more complicated than the common problem of chicken and rabbit in the same cage.

It needs to figure out the quantitative relationship, that is, who is the chicken and who is the rabbit.

The simplest way to solve the problem should be to set the unknown x.

Or take the idea of ​​​​raising your feet, assuming that all the temples are full of young monks.

Then multiply the number of steamed buns eaten by the young monks, and the difference between them is the number of big monks.

After calculating the number of big monks, and then subtracting the total number by 100, it is the number of young monks.

But Liu Ting's problem-solving process on the draft paper was quite different from this.

I saw that Liu Ting substituted in one by one, and then checked the calculation.

This method is naturally feasible, but it is a waste of time.

You know, there are 50 such multiple-choice questions in this kind of mathematics joint exam paper.

Officer Liu sneered in his heart after watching Liu Ting's problem-solving process.

Chapter 539 That's it

Director Liu thought that Liu Ting was capable, but this is it?

After reading Liu Ting's first question, Officer Liu suddenly lost interest in reading any more.

Now the exam time has passed half an hour, but Liu Ting only did 5 multiple-choice questions.

Assuming that Liu Ting can do all these questions, she can only do 20 multiple-choice questions at most.

Anyway, all the exams in the entire exam room were exhausted, and these people were asked to score 20 points.

No big deal either.

After thinking up to this point, Officer Liu shook his head and left the examination room.

Officer Liu went to other examination rooms for inspections.

Another examiner in the examination room saw the people from the Education Department leave, so he simply began to collect the test papers.

Now only Qin Chen, Liu Ting and a few candidates were left in the examination room.

Except for these students, the examiner put away all the other exam papers.

Then, the examiner took out his phone and started playing the game.

While playing, he suddenly picked up the phone.

Then, the examiner lowered his voice, flirting with the person on the other end of the conversation.

Gao Lan could tell at a glance that the examiner seemed to be looking for a partner.

Sure enough, after the examiner finished answering the phone, he seemed a little restless.

Seeing this, Gao Lan said, "This teacher can leave first if you have something to do. I'm here."

Hearing what Gao Lan said, the male teacher thanked him and left the examination room.

Gao Lan took the blank test papers from the male teacher's seat and stacked them neatly.

She rolled up the test paper with both hands and started pacing in the examination room.

But Gao Lan walked around, circling around Qin Chen.

Qin Chen was stunned by Gao Lan, "Teacher, can you stop surrounding me, I'm going to throw up!"

Seeing what Qin Chen said, Gao Lan slapped the stack of test papers on Qin Chen's desk.

"Stop talking nonsense and keep writing!" Gao Lan said.

Gao Lan threw the blank test paper to the blank space on Qin Chen's desk, and then sat at the back of the examination room.

Seeing Gao Lan leave, Qin Chen breathed a sigh of relief this time.

Then, he did it again.

Holding the pen in both hands, bowing left and right, he wrote two test papers at the same time.

After a while, Qin Chen finished the two joint exam papers.

There is still more than an hour before the end of the exam.

This time the joint exam was considered to be the city's joint exam, so the exam room was very strict, and the exam was not allowed to be handed in in advance.

Anyone who submits the papers in advance will be treated as an abstention.

Qin Chen felt like going back to the dormitory to lie down after finishing the test paper, but the next moment he thought of this painful rule.

I want to sleep, I don't feel tired now.

But now there is more than an hour before the exam, Qin Chen really doesn't know what to do.

Suddenly, Qin Chen found a pile of blank test papers stacked above the table.

This is what Gao Lan put here just now.

These test papers belong to the candidates in this examination room.

However, because of the trouble caused by the Jinling Chinese teacher just now, these exams were all abandoned.

Looking at the blank test papers, Qin Chen couldn't help reaching out and taking them.

Being idle is also idle, Qin Chen brought these test papers to him and started to do them one by one.

At first, Qin Chen only made the previous choices and filled in the blanks.

But it turned out to be too easy and not challenging at all.

So Qin Chen started to work on the next big question.

It became addictive and I couldn't stop doing it.

Qin Chen didn't simply copy the answers he had prepared.

For each test paper, he adopts different ways of solving problems to pass the time.

At this time, Gao Lan was sitting at the back of the examination room doing nothing.

Suddenly looking up, Gao Lan found that Qin Chen was actually doing someone else's test paper.

Gao Lan hurried up to Qin Chen, wanting to see what was going on.

Walking up to Qin Chen, Gao Lan found that Qin Chen's two joint exam papers had already been completed by him.

And the blank test papers of the students who gave up the test before were also messed up by Qin Chen.

As Qin Chen's head teacher, Gao Lan's first reaction was that Qin Chen was messing around.

Gao Lan also knew Qin Chen's previous math scores.

Often a test paper with a score of [-] can get [-] or [-] points.

Moreover, this is the score obtained from the multiple choice questions.

As Qin Chen's head teacher, she naturally didn't allow Qin Chen to mess around like this.

But in the next moment, when Gao Lan saw Qin Chen's problem-solving process clearly, she couldn't help but gasped.

Although Gao Lan is a graduate student in the Chinese Department, she can probably tell right from wrong when it comes to math questions in her sophomore year.

The first major math question in this mathematics entrance exam is like this.

"A fast train is 140 meters long and travels 22 meters per second, and a slow train is 125 meters long and travels 17 meters per second. How many seconds does it take for the fast train to overtake the slow train from behind?"

After reading this question, Gao Lan couldn't help but fell into deep thought.

After a long while, Gao Lan realized that it was a train overtaking problem.

She has studied this kind of topic in graduate school.

If you follow the normal problem-solving thinking, you need to apply formulas.

The time taken by the express train to overtake the slow train = the length of the two trains and the speed difference between the two trains.

按照这道题目给出的条件，列出的式子，就应该是“（140+125）（22-17）=53秒。”

Looking at Qin Chen's answer, it was indeed 53 seconds.

Gao Lan didn't expect that Qin Chen could do this kind of problem.

Although this question is placed in the first question of the mathematics entrance examination, it is relatively simple.
