Three minutes passed quickly.
When the last minute arrived, the door opened.
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 is 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 empty.
I don’t know if Di Renjie did it on purpose or what.
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. Was this done by a child? What a prodigy.
Li Min didn't care about those two questions. Instead, I checked his answer first.
He reads very quickly.
Almost with a glance, you can tell whether he got the answer right. He looked at all 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 him 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: "You answered 98 out of a total of 100 questions. In fact, 80 questions were correct, 18 questions 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.
So shocking.
At the same time, I am also confused, is the question really that difficult?
So she took the question on the paper and read it.
You don’t know if you don’t look at it, but just by looking at it, you feel depressed.
Because the above questions directly refreshed her knowledge.
There are still such difficult questions in the world.
If she came, she might only get half of the answers right.
The gap between myself and the other party is really too big! I didn’t expect Li Min’s talent to be so powerful! It's so difficult to ask such a difficult question!
After all, Li Min is still stronger. Better than anyone else! This is why he was able to found the group. And what makes the group so powerful, right? !
anyway.
Di Renjie can answer 80% of the answers. He is also a genius.
At the same time, Li Min was even more of a genius for being able to come up with such a question.
Completely crushing everyone.
This is where Li Min excels.
She touched her belly like this, and their children would probably be smarter in the future. You must follow Li Min and let Li Min educate you! It is simply a blessing for the Tang Dynasty that there are 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 handle 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 suddenly said.
"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 said suddenly.
Li Min is naturally not stingy about sharing knowledge.
Then, he read the title.
A line of troops is 100 meters long and is marching. The messengers pass orders from the end of the line to the front of the line and back 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 messenger remained unchanged. How many meters did the messenger travel in total?
This question is indeed a bit difficult to solve.
But for Li Min, this question was given by him, so it was naturally not difficult.
So, he said: "I'll write it down and you'll know after you read it 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 queue to the end of the queue)
From 1 and 2, [(v2/v1)^2-2*(v2/v1)+1]-2=0
The solution is v2/v1=±√2 +1 v2/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, it dawned on me.
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 to cross a 1,000-kilometer-long desert to sell 3,000 carrots. It is known that a donkey can carry 1,000 carrots at a time, but it has to eat one carrot for every kilometer it travels.
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 was beyond 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, so I'll 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, sir!"
After Di Renjie finished speaking, he left.
This kid is really reassuring.
