(Sweet, the title should be: Where did the penny go? Sorry, I can correct the content if it is wrong, but I can’t change the title if it is wrong!)
Inside the teaching building.
The eight new students, Sun Zifan and Yu Dongcai, were not the only ones who had headaches. The other students started to have headaches as soon as they saw the first question.
"In a division equation, the sum of the dividend, divisor, quotient, and remainder is 75. It is known that the quotient is 8, the remainder is 2, the dividend is ___, and the divisor is ___."
In previous exams, the first question was usually very simple, but this time, the first question came directly from a quadratic equation question, which confused many people.
Many students were doing calculations quickly on their scratch paper while cursing in their minds. Although Li Zexuan had explained this quadratic equation to them, it would still take a lot of effort to solve it. They could only pray that the following questions would not be so perverted. That's it.
Unexpectedly, some people finally solved the first question, but when they saw the second question, they were dumbfounded again, and saw that it said:
"There is a well that is 7 feet deep. A snail climbs up from the bottom of the well. It climbs 3 feet during the day and falls 2 feet at night. Can the snail climb out of the well in ___ day?"
Damn it! Damn it!
Sir, you are not giving us a way to survive! What is this question? How come I've never seen it before? Someone is going to die! Isn't it going to be full of perverted questions like this
The students roared in their hearts, complaining that Li Zexuan's questions were too perverted.
Even Li Tai, Ke Shiqing, Zeng Ziran, Meng Wenhao, Qin Huaiyu, Tiedan and others with the best grades frowned deeply.
Meng Wenhao's eyes were fixed on this question. If his eyes had energy, this test paper would be instantly penetrated by this majestic energy, right
"Climb three feet in one day and fall two feet. That is equivalent to climbing up one foot every day. A total of seven feet. Do you have to climb seven days? No, no, this question is definitely not that simple!"
Meng Wenhao's mind was racing, and various thoughts kept flashing through his mind. His hands did not stop, and he was writing and drawing on the draft paper, looking for ideas to solve the problem.
The other students were all Alexander, with sweat dripping from their foreheads, and the atmosphere in the entire classroom suddenly became extremely solemn.
Xu Hongzhi sat on the podium and looked at the group of struggling children below. He sighed helplessly. After getting the test questions yesterday, he tried to do them. If he did every question with all his strength, two He couldn't finish it at all.
The test papers that Li Zexuan gave were very large. After all, the test lasted for two hours (four hours), and the number of questions he gave was basically twice that of the test papers in his previous life.
In the previous exam, because the test questions were simple, many people did not feel pressed for time, but this time is different. There is basically no question in the entire test paper that is the kind of scoring question that can be seen at a glance. I believe it won’t be long before students We will definitely find that there is not enough time.
Li Tai was also a little overwhelmed by the second novel question, but how could he, Li Tai, admit defeat? This question is not unsolvable. If you think about it carefully, you will definitely be able to find the answer.
"The snail actually only moves up one foot per day. Most people would think that if it moves one foot per day, it will naturally reach the wellhead in seven days. But the problem is definitely not that simple. If the snail has reached the wellhead, it will not fall. This This is probably the most confusing part of this issue.
So the snail climbed four feet in the first four days, climbed three feet during the day on the fifth day, and crawled out directly, so the snail actually climbed out of the well in five days! Perfect! Li Tai is indeed the smartest, hehe! "
A proud smile appeared on Li Tai's face, and he quickly wrote down the answers. However, inadvertently, he glanced at the hourglass on the podium and was surprised. It took him nearly a quarter of an hour to complete the two questions. Come on
Li Tai glanced at the vast sea of questions behind him, and the proud look on his face disappeared. He took a deep breath and continued to engage in "battle".
"Clang clang clang!"
Just when all the students were still immersed in the sea of questions, the gongs and drums for the first period of the Imperial College had already sounded. The students were shocked. They did not expect that time passed so quickly. At this time, many people did not even finish filling in the blanks. One can imagine how perverted the questions Li Zexuan asked this time!
"Oops! It seems that some of the questions are too difficult and need to be abandoned!"
Tiedan had just completed the last question of filling in the blanks at this time. He estimated the time required for the remaining questions and found that some were not enough, so he secretly made a decision.
Smart students all have similar ideas: do the easy things first and then the hard ones, otherwise they will definitely not get high marks.
… … … …
Of course, they were "cut off" many times along the way, but many students finally got to the last question, including Meng Wenhao, Li Tai, and Ke Shiqing.
At this time, Li Tai touched the sweat on his forehead, breathed a sigh of relief, and began to answer. A quarter of an hour later, he finally came up with an idea. He spent a while and wrote the answers on the test paper step by step. Then he was about to go back and do the questions that he had not answered before, but he saw that there were still more questions at the back. A big question.
"Damn it, what kind of medicine did Li Zexuan take? This is too much!"
Li Tai was almost driven crazy, but when he saw the text in parentheses after the additional question, his heart moved and he stopped scolding her.
"Twenty points will be added to the total score for correct answers, and no points will be deducted for wrong answers!"
Li Tai turned back the paper and found that there were four or five questions that he had not done before, which totaled only about ten minutes. But now there was less than two quarters of an hour left. If he used them all, he might not be able to complete them. All the previous questions were answered correctly. After all, those questions were the ones he found most difficult. It would be better to concentrate on the last additional question. If he got it right, he would get twenty points.
Li Tai immediately made a decision in his mind and began to read the last additional question with all his heart.
"Three people went to stay for 30 cents a night. Each of the three people paid ten cents. They collected 30 cents and gave it to the boss. Later, the boss said that today's discount was only 25 cents, so he took out five cents. He ordered the inn boy to return it to them. The boy secretly hid two coins, and then distributed the remaining three coins to the three people, each of whom received one cent. This three times nine is equal to twenty-seven coins, plus The two pennies hidden by the waiter are equal to twenty-nine pennies. Where did the other one penny go? Please explain the reason!"
"Huh~? This question makes sense, but according to this calculation, where did the penny go?"
Li Tai was not the only one to discover the advantage of additional questions. Sun Tzu Fan also discovered that in the entire set of test papers, there were only a dozen or so questions that did not include Arabic numerals and arithmetic symbols, including this one, and the bonus points were very high. , Sun Tzu Fan fell in love with this question at a glance, but what was said in the question had already detoured him, and he didn't know where the penny went!

Third update!
Thank you for loving you and this generous reward that belongs to me! There is nothing to repay, so I can only seize the time to code and see if I can complete a chapter before twelve o'clock!
