Otaku Engineer in Great Tang Dynasty Chapter 226: Where did the penny go?
(Khan, where should the penny go for the title? Sorry, I can change the content if it is wrong, but I can’t change it if the title is wrong!)
In the church building.
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, the divisor, the quotient, and the remainder is 75. The known 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-variable 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 effort. They can only pray for the next problem. Just don't be so perverted.
Who knows that some people have finally made the first question, and when they see the second question, they are dumbfounded again, as it says 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 2 feet down at night. Can the snail climb out of the well in ___day?"
Fuck! Damn it!
Sir, this is not giving us a way to survive! What is this problem? Why have you never seen it before? It's going to die! Isn't it all this kind of perverted questions?
The students roared wildly 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, then it is equivalent to climbing one foot every day, a total of seven feet, is it necessary to climb seven days? No, it's definitely not that simple!"
Meng Wenhao's thoughts changed 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 Alexanders, sweating 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, but if he tried to do every question with all his strength He couldn't finish it at all in two hours.
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 that 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 tell the answer at a glance. After a while, the students will definitely find that there is not enough time.
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 head of the well in seven days. But the problem is definitely not that simple. If the snail has reached the head of the well, it will not fall. Now, this should be the most confusing part of this question.
Then the snail climbed four feet four days ago, and on the fifth day it climbed three feet during the day, and climbed out directly, so the snail actually crawled out of the well five days ago! 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. , Is this okay?
Li Tai glanced at the vast sea of inscriptions behind him, the smug look on his face was never seen again, he took a deep breath and continued to "fight".
"Clang clang!"
Just when all the students were still immersed in the sea of questions, the gongs and drums for 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 fill in the blanks. After finishing it, one can imagine how abnormal Li Zexuan's question is!
"Oops! It seems that there are some too difficult questions, I need 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.
Clever students all have similar ideas, the easy first and then the 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 did 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 go 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~IndoMTL.com~ But when he saw the text in the parentheses after the additional question, his heart moved and he stopped cursing his mother.
"20 points will be added to the total score for correct answers, no points will be deducted for incorrect answers!"
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. All of them are not used. He must be able to answer all the previous questions correctly. After all, those questions are the most difficult questions he finds. It's better to concentrate on doing the last additional question and add 20 points if you get it right.
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 the three paid ten ren and collected enough 30 ren and gave it to the boss. Later, the boss said that today’s discount is only 25 wen. Out of five articles, he ordered the inn servants to return them to them. The servants secretly hid two articles, and then distributed the remaining three cents to the three people, each of whom received one cent. These three times nine equals twenty-seven. The text, plus the two pennies hidden by the waiter, equals twenty-nine pens. Where did the other penny go? Please explain why!"
"Huh~? This question is very reasonable, but according to this calculation, where did the penny go?"
It is not only Li Tai who discovered the advantages of the additional questions, but Sun Zifan also discovered that on the whole set of examination papers, only a few dozen questions, without Arabic numerals and arithmetic symbols, included this one, and added points. It's still very high. Sun Tzufan saw this question at a glance. It's just that what the question said had already got him in. He didn't know where the penny went!
………………
Third more!
Thank you for my 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!
