Chapter 226: Where did the 1 cent go?

(Khan, where should the penny go for the title? Sorry, I can change the content if it is wrong, but it can’t be changed if the title is wrong!)
Inside the teaching house.
The eight new students, Sun Zifan and Yu Dong, are not the only people who have headaches. The rest of the students have had headaches since they saw the first question.
"In a division formula, 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 the previous exams, the first question was generally very simple, but this time, the first question came directly with a two-dimensional linear equation question, which directly confuses many people.
Many students are swiftly calculating on the draft paper while scolding their mothers in their hearts. Although Li Zexuan has taught them this quadratic equation, if it is solved, it will take a lot of work. They can only pray that the following questions will not be so abnormal. That's it.
Unexpectedly, some people have finally made the first question, and when they saw the second question, they were dumbfounded again, as they wrote above:
"A well is 7 feet deep. A snail crawls 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, this is not giving us a way to survive! What question is this? Why have you never seen it before? It's going to die! Isn't it all this kind of perverted questions?
The students roared in their hearts, complaining that Li Zexuan's questions were too abnormal.
Even the best performers like Li Tai, Ke Shiqing, Zeng Ziran, Meng Wenhao, Qin Huaiyu, Tiedan and others frowned deeply.
Meng Wenhao fixed his eyes on this question, if there is energy in his eyes, this test paper is afraid that this majestic energy will instantly penetrate it, right?
"Climbing three feet a day and falling two feet a day is equivalent to climbing one feet a day, a total of seven feet. Is it necessary to climb seven days? No, it's definitely not that simple!"
Meng Wenhao's thoughts turned sharply, and various thoughts flashed in his mind without stopping, and he was constantly writing and drawing on the draft paper, looking for ideas for solving problems.
The rest of the students were all Alexander, with sweat faintly on their foreheads, and the atmosphere of the entire teaching house suddenly became extremely solemn.
Xu Hongzhi sat on the podium and looked at the group of hard-pressed children below. He also sighed helplessly. After he got the test questions yesterday, he tried to do it. As a result, if he tried his best to do every question, two He couldn't finish it at all.
Li Zexuan's test papers have a large amount of questions. After all, the test time is two hours (four hours), and the amount of questions he put out is basically twice the amount of those in the previous life.
In the previous exam, due to the simple test questions, many people did not feel that the time was tight, but this time it was different. There was basically no question on the whole test paper that was a sub-item that could see the answer at a glance. I believe it will not be long, students We will definitely find that time is not enough.
Li Tai was also a little overwhelmed by the second novel question, but is Li Tai the one to admit defeat? This question is not unsolvable, think about it, you can definitely find the answer.
"The snail actually only moves up by one foot every day. Most people would definitely think that one foot in a day will naturally reach the well head in seven days. But the problem is definitely not that simple. If the snail has already reached the well head, it won’t fall anymore. It should be the most confusing part of this question.
So the snail crawled four feet in the first four days, and on the fifth day it climbed three feet in the day, and climbed out directly, so the snail actually crawled out of the well five days! perfect! I, Li Tai, is the smartest, hehe! "
There was a smug smile on Li Tai's face, he quickly wrote the answer, but inadvertently, he glanced at the hourglass on the podium, and was shocked. It took him nearly a quarter of an hour for the two questions. Come on?
Li Tai glanced at the vast sea of ​​inscriptions behind him, and the triumphant expression on his face was no longer seen. He took a deep breath and continued to "fight".
"Clang clang!"
While all the students were still immersed in the sea of ​​questions, the gongs and drums of the first get out of class of the Imperial College had been sounded. The students were shocked. They didn’t expect the time to pass so fast. At this time, many people didn’t even finish filling in the blanks. One can imagine how abnormal Li Zexuan's question is!
"Oops! It seems that some of the questions are too difficult to give up!"
Tiedan had just completed the last question of the fill-in-the-blank question at this time. He estimated the time required for the remaining questions, and after finding that some were not enough, he secretly made a decision.
Smart students all have similar ideas, easy first and then difficult, otherwise they will definitely not get high scores.
……………………
All the way to "pass through the generals", of course, have been "cut" many times, but many students finally achieved the last question, Meng Wenhao, Li Tai, and Ke Shiqing were among them.
Li Tai touched the sweat on his forehead at this time, breathed a sigh of relief in his heart, and began to answer. After a quarter of an hour, he finally came up with an idea. It took him a while to write the answers on the test paper step by step, and then he was about to turn back and do the questions that he hadn’t done before. A big question.
"Fuck, what medicine did Li Zexuan take! It's too much!"
Li Tai was almost driven crazy in his heart~EbookFREE.me~ However, when he saw the text in parentheses after the additional question, his heart moved and he stopped cursing his mother.
"A correct answer will add 20 points to the total score, no points will be deducted for a wrong answer!"
Li Tai turned back to the paper and found that there were four or five questions that were not done before, and the total amount was about ten minutes. Now there is only less than two quarters of an hour left. If you use all of them, you may not be able to use them. All the previous questions were answered correctly. After all, those questions were the most difficult questions he found. It would be better to concentrate on doing the last additional question, and add 20 points if it is correct.
Li Tai made a decision in his heart and began to look at the last additional question wholeheartedly.
"There were three people who went to stay, 30 wen a night, and each of them paid ten ren and made up enough 30 wen and gave it to the boss. Later, the boss said that today’s discount is only 25 wen, so he took out five. Ordered the inn servant to return it to them. The servant secretly hid two pennies. Then, he shared the remaining three cents among the three people, each of whom received one penny. This three times nine equals twenty-seven pens, plus The two pennies hidden by the waiter are equal to twenty-nine pens. Where did the other penny go? Please explain why!"
"Huh~? This question is very reasonable, but according to this calculation, where does the penny go?"
Li Tai was not the only one who discovered the advantages of the additional questions, Sun Zifan also discovered that on the whole set of test papers, only a few dozen questions were included, which did not contain Arabic numerals and arithmetic symbols, which included this one, and the extra points were very high. , Sun Zifan saw this question at a glance, but the question mentioned in it had already turned him in, and he didn't know where the penny went!

Third!
Thank you for your reward for loving you! If you don't want to report, you can only hurry up on the time code word, and see if there is still a chapter before twelve o'clock!
