Chapter 539

Originally, Liu Gan thought Liu Ting had some abilities. Unexpectedly, that's it?

After reading Liu Ting's first question, director Liu immediately lost interest in reading it again.

Now half an hour has passed, but Liu Ting has only done five multiple-choice questions.

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

Anyway, the whole examination room ran out of exams. Let these people do 20 points.

It's no big deal.

At this point, Liu shook his head and left the examination room.

Liu Gan went on a tour to other examination rooms.

Another examiner in the examination room saw the people from the education department leave. He simply began to collect his papers.

Now there are only Qin Chen, Liu Ting and several candidates left in the examination room.

Apart from these students, the examiner collected all the other examination papers.

Then, the examiner took out his mobile phone and began to play games.

Playing, he suddenly answered the phone.

Then, the examiner lowered his voice and became ambiguous with the person at the other end of the sentence.

Gao Lan saw that the examiner seemed to be making an object.

Sure enough, the examiner looked a little fidgety after answering the phone.

Seeing this, Gao Lan said, "if the teacher has something to do, he can leave first. I'm here."

Hearing Gao Lan's words, the male teacher thanked him and left the examination room.

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

She rolled up her test paper with both hands and began to pace in the examination room.

However, Gao Lan walked around in circles around Qin Chen.

Qin Chen was dizzy by Gao Lan. "Teacher, can you stop turning around me? I'm going to vomit!"

Seeing Qin Chen saying so, Gao Lan took a stack of test papers in his hand and directly photographed them on Qin Chen's table.

"Less nonsense, keep writing!" Gao Lan.

Gao Lan threw the blank test paper into the blank space of Qin Chen's table, and then sat behind the examination room.

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

Then he did it again.

Holding a pen in both hands, he opened his bow from left to right and wrote two test papers at the same time.

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

It's more than an hour before the end of the exam.

This joint examination is thought to be the joint examination of the whole city, so the examination room is very strict and it is not allowed to hand in the examination paper in advance.

However, those who hand in their papers in advance shall be treated as abandoned.

Qin Chen had finished the test paper like lying back in the dormitory, but the next moment he thought of the rule of egg pain.

I want to sleep. I'm not 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 stack of blank papers stacked above the table.

This is what Gao Lan put here just now.

These papers are from the candidates in this examination room.

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

Qin Chen looked at these blank papers and couldn't help reaching for them.

Being idle is also idle. Qin Chen took these papers to him and began to do them one by one.

At first, Qin Chen only made the front choice and filled in the blanks.

But later found that it was too simple and not challenging at all.

So Qin Chen began to do the big questions behind.

This is addictive and can't stop.

Qin Chen doesn't simply copy his answers.

He passed the time by taking different ideas for solving problems in each test paper.

At this time, Gao Lan is sitting behind the examination room doing nothing.

Suddenly looking up, Gao Lan found that Qin Chen was actually doing other people's test papers.

Gao Lan hurried to Qin Chen and wanted to see what was going on.

Walking to Qin Chen, Gao Lan finds that the two joint examination papers belonging to Qin Chen have been finished by him at this time.

The blank test paper of the students who abandoned the test before was also made by Qin Chen.

As Qin Chen's head teacher, Gao Lan's first reaction was that Qin Chen was doing it in disorder.

Gao Lan knows Qin Chen's math scores before.

Often a 100 point test paper can get one or two tenths.

Moreover, this is the score obtained from the cormont multiple-choice question.

As Qin Chen's head teacher, she naturally doesn't allow Qin Chen to make such nonsense.

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

Although Gao Lan is a graduate student in the Chinese Department, she can probably tell right from wrong about math problems in her sophomore year.

This is the first big math problem in the joint math exam.

"An express train is 140 meters long, 22 meters per second, and the slow train is 125 meters long, 17 meters per second. How many seconds does it take for the express train to catch up with the slow train from behind to surpass the slow train?"

After reading this topic, Gao Lan couldn't help falling into meditation.

After a long time, Gao Lan realized that this was a Train Overtaking problem.

She studied this topic at the graduate stage.

If you follow the normal way of solving problems, you need to apply the formula.

The time taken by the express train from catching up to overtaking the slow train = the body length of the two trains and the speed difference between the two trains.

According to the conditions given in this topic, the formula listed should be "(140 + 125) (22-17) = 53 seconds."

Looking at the answer given by Qin Chen, it is indeed 53 seconds.

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

Although this question is the first question in the joint mathematics examination, it is relatively simple.

But the comparison is a knowledge point that can only be mastered at the graduate stage. Gao Lan didn't expect that Qin Chen could master it at the undergraduate stage.

But this is not over. Qin Chen not only used this method to solve the problem.

He also used many other different methods.

For example, first subtract the slow speed from the fast speed, and then divide it directly by the speed difference.

Or, multiply the ratio of the velocity difference by the ratio of the velocity difference.

These problem-solving ideas, the answer is 53 seconds.

This makes Gao Lan a little eye opener.

She never thought that she could write so many solutions to the problem of Train Overtaking in addition to applying formulas.

This is not over. Gao Lan looked at the second big question curiously.

"For a highway, it takes 24 days for team a to repair it alone, and 30 days for team B to repair it alone. After several days of cooperation between Party A and Party B, team B stopped to rest, and team a continued to repair it for 6 days."

"How many days has team B repaired?"

After reading the math problem, Gao Lan's brain was buzzing.

This is obviously beyond the mathematical knowledge of undergraduate and even graduate students.

Think of such a difficult topic, let alone graduate students can't do it.

I'm afraid even ordinary doctoral students can't do it.

She knew that it was very difficult for the education department to set up a topic this time. She didn't expect it to be so difficult.

In the morning's Chinese exam, the classical Chinese used a "University" just unearthed

Unexpectedly, the Jinling education department had such a serious problem in the afternoon math exam.

At this moment, Gao Lan felt the deep malice of the problem group.

Gao Lan saw Qin Chen write the answer and looked at it curiously.
