Di Renjie came out holding several sheets of paper filled with writing.
"Sir, I have answered!"
he said.
Di Renjie could have stayed longer.
But he was stubborn and didn't do that.
It can be said that the timing was just right.
Li Min took it and took a look. Several pieces of paper were filled with words.
It can be seen that Di Renjie is really attentive.
However, among these pieces of paper, there are two questions that are blank.
I don’t know if Di Renjie did it on purpose or what happened.
Why are these two questions left blank?
Either I can’t do it or I don’t have time.
Or maybe they think they can be right.
I intentionally left two questions.
All this is unknown.
Ji Ruxue was also shocked. Is this still something a child did? What a child prodigy.
Li Min didn't care about those two questions. Instead, he checked his answers first.
He reads very quickly.
Almost at a glance, you can tell whether he got the answer right. He looked at the answers to the process. Some of the answers were right, but the process was wrong. When the variables changed, the results would be different. For such questions, he only gave
He's half! There have to be two questions, so this one counts as one.
Overall, Di Renjie is still very good, with such a high accuracy rate.
Then, he said to him: "There are a total of 100 questions, and you answered 98 of them. In fact, 80 of them were correct, 18 were wrong, and two questions were blank!"
Li Min said this. I really didn’t expect that he could answer 80 questions correctly. It seems that Di Renjie is really a smart person!
Such talents are also very rare.
At the same time, Di Renjie did not even refute.
Instead, he said: "I roughly know how many questions I answered correctly, which is pretty much what the teacher said."
It turned out that he had already calculated how many questions he had answered correctly.
So, since he didn't answer 90% of the questions correctly, he wouldn't be able to do what he wanted this time. He would have to stay in Chang'an and study again.
Ji Ruxue was also quite shocked. She originally thought Di Renjie could get 90% of the answers correct, but unexpectedly she couldn't.
This is shocking.
At the same time, I am also confused, is the question really that difficult?
So she took the topic on the paper and read it.
You wouldn't know it if you didn't look at it, but just by looking at it, I immediately felt depressed.
Because the above questions directly refreshed her knowledge.
There are still such difficult questions in the world today.
If she came, she might only get half of the answers right.
The gap between myself and the other party is really huge! I didn’t expect that Li Min’s talent is so strong! He can actually ask such difficult questions!
After all, Li Min is still stronger. More powerful than anyone else! This is why he was able to found the group and why it became so powerful, right?!
anyway.
Di Renjie can answer 80% of the answers, so he is also a genius.
At the same time, Li Min is even more of a genius for being able to come up with such a question.
Completely overwhelmed everyone.
This is where Li Min excels.
In this way, she touched her belly. I am afraid that their children will be smarter in the future. They must follow Li Min and let Li Min educate them! It would be a blessing for the Tang Dynasty to have five more people like Li Min in the Tang Dynasty!
In a few months, the baby will be born.
At that time, there were just five of them coming out together.
In a few years, he will even be able to help Li Min deal with major issues of the Shengtang Group. Let Li Min spend more time with him!
When she thought of this, a happy smile filled her face.
Then Li Min said:
"We agreed, you should know what you are going to do, right?"
In this way, Di Renjie must study hard and not think about anything else.
"Yes, sir, I will definitely study hard in the library. I hope that after three years, sir, you will not reject me!"
"Of course! I do what I say! You can rest assured on this!" Li Min means what he says, and everyone agrees on this.
"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 solve the questions for me."
The studious Di Renjie suddenly said this.
Li Min is naturally not stingy about sharing knowledge.
Then, he read the title.
A queue is 100 meters long and is marching. The messenger conveys orders from the end of the queue to the front and back to the end of the queue without stopping. During this time, the queue has advanced 100 meters. It is known that the moving speed of the team and the messenger remains unchanged.
, asked the ordering soldier how many meters he ran in total?
This question is indeed a bit difficult to solve.
But for Li Min, since this question came from him, it is naturally not difficult.
So, he said: "I'll write it down and you can see for yourself!"
"Thank you sir!"
Then Li Min wrote:
Assume that the team speed V1 and the speed of the messenger V2 are the time t when the messenger arrives at the head of the queue.
There is the following relationship 2*t-v1*t=100
1*(100/v1-t) v2*(s/v1-t)=100(s/v1-t the time from the beginning of the platoon to the end of the platoon for the messenger)
From 1 and 2, [(v2/v1)^2-2*(v2/v1) 1]-2=0
The solution is v2/v1=±√2 1v2/v1>0∴v2/v1=√2 1≈2.414
The distance traveled by the messenger is (100/v1)*v2=241.4 meters
Faced with such an organized way of answering questions.
Di Renjie was shocked when he saw it.
At the same time, I suddenly realized.
So that’s it.
Isn’t this solution too clear?
Li Min is indeed no ordinary person.
Unexpectedly, I could answer like this.
"What about the second question?"
Di Renjie asked again.
Question 2: A businessman rides a donkey through a 1,000-kilometer-long desert to sell 3,000 carrots. It is known that the donkey can carry 1,000 carrots at a time, but it will eat another carrot every 1 kilometer traveled.
Question: How many carrots can a merchant sell at most?
This question is even more difficult.
Di Renjie was stumped.
Ji Ruxue, who was reading the question, was also shocked.
This has exceeded her imagination.
And Li Min’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 two loads for the second time. Suppose the donkey walks Y kilometers and unloads carrots for the second time:
3Y=1000, Y=333.3, leaving 1000 carrots;
At this time, the total distance traveled is: 200 333.3=533.3 kilometers,
The remaining 1000-533.3=466.7 kilometers only need to be carried out once, eating 466 radishes.
Therefore, the number of radishes that can be sold is 1000-466=534 (roots);
…
As soon as Di Renjie saw the answer, he patted his thigh directly.
"Sir, I admire you! I admire you!"
Di Renjie seemed convinced.
"There are other questions that were answered incorrectly. Let me answer them as well."
Li Min said again.
"Thank you sir!"
Immediately afterwards, he solved the problem.
This set of questions can be solved very smoothly.
Di Renjie's eyes were filled with admiration.
"Sir, can I take this paper?"
Finally, Di Renjie asked.
“Of course it’s possible!”
"Mr. Xie, starting from this afternoon, I will stay in the library! I can't let you down!"
