The first rebel of the Tang Dynasty

Chapter 1708 A Reassuring Child

3 minutes passed quickly.

When the last minute came, the door opened.

Di Renjie came out with a few sheets of paper full of words.

"Sir, I have answered!"

he said.

Di Renjie could have stayed longer.

But stubbornly, he didn't do that.

It can be said that the timing is just right.

Li Yin took it over and saw that several sheets of paper were full of words.

It can be seen that Di Renjie really put his heart into it.

However, among these few sheets of paper, there are two questions that are empty.

I don't know if Di Renjie did it on purpose, or what.

Why are these two questions left blank?

Is it because I don't know how to do it, or because I don't have time.

Or think you can be right.

Intentionally left two questions.

All this is unknown.

Ji Ruxue was also stunned, was this something a child did?What a child prodigy.

Li Yin didn't care about those two questions.Instead, check his answer first.

He looks fast.

Almost at a glance, he knew whether he got the answer right or not.He reads all the answers in the process. Some answers are just right, but the process is wrong. When the variable changes, the result will be different. For such a question, he only gives him half!There are always two questions, so this counts as one.

Generally speaking, Di Renjie is still very good, and he has such a high accuracy rate.

Then, he said to him: "A total of 98 questions, you answered 80 questions, in fact, 18 questions were correct, [-] questions were wrong, and two questions were blank!"

Li Yin said so.I really didn't expect that he could answer 80 questions correctly. It seems that Di Renjie is really a smart person!

Such talent is also very rare.

At the same time, Di Renjie didn't even refute.

Instead, he said, "I probably know how many questions I got right, which is about the same as what my husband said."

It turned out that he had figured out how many questions he had answered correctly.

In other words, he didn't answer [-]% of the questions correctly, so he couldn't do what he wanted this time, and he had to stay in Chang'an to study again.

Ji Ruxue was also quite shocked. Originally, she thought that Di Renjie could answer [-]% of the questions correctly, but unexpectedly he couldn't.

In this way, it is shocking.

At the same time, I was wondering, is the topic really that difficult?
So she took the topic on the paper and read it.

I don't know if I don't look at it, just looking at it makes me feel depressed.

Because the above topic directly refreshed her cognition.

There are still such difficult problems in this world.

If she came, she might only get half of the answers right.

The gap between yourself and the other party is really too big!Unexpectedly, Li Yin's talent is so powerful!How could such a difficult question be asked!
After all, Li Yin is still stronger.Better than anyone!This is why he was able to create the group.And what makes the group so powerful, right? !
anyway.

Di Renjie can answer [-]% of the answers, that's a genius.

At the same time, for Li Yin to be able to come up with such a problem, he is a genius.

Completely crushed everyone.

This is where Li Yin excels.

So she touched her stomach, and their children might be smarter in the future.You must follow Li Yin and let Li Yin educate you!It is simply a blessing for Datang that there are five more people like Li Yin in Datang!
In a few months, the baby will be born.

At that time, the five came out together.

In a few years, he will even be able to help Li Yin deal with the major affairs of Shengtang Group.Let Li Yin spend more time with himself!
Thinking of this, a happy smile filled her face.

Then Li Yin said again:

"We agreed, what are you going to do, you should know?"

In this way, Di Renjie has to study hard and can't think about other things.

"Yes, sir. I will definitely study hard in the library. I hope that after three years, sir, you won't reject me!"

"Of course! I will do what I say! You can rest assured about this!" Li Yin said what he said, and everyone agrees.

"It's just sir..."

Di Renjie said suddenly.

"What's wrong? Tell me!"

"There are two questions here that I don't know. They are the two blank questions. I would like to ask sir to explain the questions for me."

The studious Di Renjie said suddenly.

Li Yin is naturally not stingy with knowledge sharing.

Then, he looked at the topic.

A line is 100 meters long and is marching. The messengers pass orders from the end of the line to the head of the line, and then return to the end of the line without stopping.During this period of time, the team advanced 100 meters. It is known that the moving speed of the team and the orderly remains unchanged. How many meters did the orderly run in total?
This question is really difficult to solve.

But for Li Yin, since he came up with this topic, it is naturally not difficult.

So, he said: "I'll write it down, you can see for yourself!"

"Thank you sir!"

Then Li Yin wrote:
Let team speed V1 messenger speed V2 messenger arrive at the top of the queue time t
There is the following relationship 1.v2*t-v1*t=100
2.v1*(100/v1-t)+v2*(s/v1-t)=100 (s/v1-t传令兵从排头到排尾的时间）

由1和2推出[（v2/v1)^2-2*(v2/v1)+1]-2=0
解得v2/v1=±√2 +1 v2/v1>0∴v2/v1=√2+1≈2.414
The distance of the messenger is (100/v1)*v2 =241.4 meters

Faced with such a methodical way of answering questions.

Di Renjie was shocked when he saw it.

At the same time suddenly realized.

It turned out to be the case.

This solution is too clear, right?
Li Yin is really not an ordinary person.

Unexpectedly, it can be answered like this.

"What about the second question?"

Di Renjie asked again.

第二题：一个商人骑一头驴要穿越1000公里长的沙漠，去卖3000根胡萝卜。已知驴一次性可驮1000根胡萝卜，但每走1公里又要吃掉1根胡萝卜。

Q: How many carrots can a merchant sell at most?
This question is more difficult.

Di Renjie stumped.

Ji Ruxue, who was reading the question, was also shocked.

This has exceeded her imagination.

And Li Yin's answer is:

Suppose the donkey walks X kilometers and unloads the carrot for the first time:
5X=1000 (the number of radishes eaten is also equal to the number of kilometers traveled)

X=200, then there are 2000 carrots in total;
The donkey only needs to carry it twice for the second time. If the donkey walks Y kilometers and unloads the carrots for the second time:
3Y=1000, Y=333.3, there are 1000 carrots left;

At this time, the total distance traveled: 200+333.3=533.3 kilometers,

而剩下的1000-533.3=466.7公里只需要1次驮出，吃466根萝卜

So the number of radishes that can be sold is 1000-466=534 (root);
……

When Di Renjie saw the answer, he patted his thigh directly.

"Sir, admire! Admire!"

Di Renjie seemed convinced.

"There are other wrong answers, let me answer them together."

Li Yin said again.

"Thank you sir!"

Immediately afterwards, he solved the problem.

This set of questions can be solved in a smooth manner.

Let Di Renjie's eyes be filled with admiration.

"Sir, can I take this paper?"

Finally, Di Renjie asked.

"Of course it is possible!"

"Mr. Xie, from this afternoon onwards, I will live in the library! I can't let you down!"

After Di Renjie finished speaking, he left.

This child is really reassuring.
