(Khan, the title should be where did that penny go?) Sorry, I can change the content if I write it wrong, but I can't change the title if I write it wrong! ）

Inside the parishion.

The eight new students who have headaches are not only Sun Zifan and Yu Dongcai, but the rest of the students have had some headaches since they saw the first question.

"In a division equation, the sum of the four numbers of the dividend, the divisor, the quotient, and the remainder is 75, and the quotient is known to be 8, the remainder is 2, the dividend is ___, and the divisor is ___."

In the previous exams, the first question was usually very simple, but this time, the first question directly came to a binary equation question, which directly confused many people.

Many students are doing rapid calculations on scratch paper, and at the same time scolding their mothers in their hearts, although Li Zexuan has told them about this yuan quadratic equation, but if they solve it, they will have to spend a lot of effort, they can only pray that the questions behind them are not so perverted.

Who knows that some people finally made the first question, and when they saw the second question, they were dumbfounded, and saw that it was written:

"There is a well 7 zhang deep, there is a snail from the bottom of the well to climb up, climb 3 zhang during the day, fall down 2 zhang at night, snail ___ day can climb out of the well?"

it! it!

Sir, this is not for us to live! What is this question? How come you've never seen it? It's going to kill you! It won't be all this kind of perverted question, right?

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, Tie Dan and others with the best grades frowned deeply.

Meng Wenhao's eyes were staring at this question, if his eyes had energy, he was afraid that this test paper would be instantly pierced by this majestic energy, right?

"Climb three zhang a day and fall two zhang, which is equivalent to climbing up one zhang a day, a total of seven zhang, do you want to climb for seven days? No, no, this question will definitely not be that simple! ”

Meng Wenhao's mind was in a hurry, all kinds of thoughts kept flashing in his mind, and his hands did not stop, he was constantly writing and drawing on scratch paper, looking for ideas to solve the problem.

The rest of the students were Alexander, sweating faintly on their foreheads, and the atmosphere of the entire teaching house suddenly became extremely solemn.

Xu Hongzhi sat on the podium, looking at the group of hard-working babies below, he also sighed helplessly, after he got this test question yesterday, he tried to do it, but if he did every question with all his might, he couldn't finish it in two hours.

Li Zexuan's test papers have a large amount of questions, after all, the exam time is two hours (four hours), and the amount of questions he produces is basically twice that of those test papers in his previous life.

In the previous exam, due to the simplicity of the test questions, many people did not feel that time was tight, but this time it was different, there was basically no question on the entire test paper that could see the answer at a glance.

Li Tai was also a little overwhelmed by the second novel question, but how could he, Li Tai, be the one who gave in? This question is not unsolvable, and if you think about it, you will definitely be able to find the answer.

"The snail actually only moves up one zhang a day, and the average person will definitely think that one zhang a day, seven days will naturally reach the wellhead. But the problem is certainly not so simple, if the snail has reached the mouth of the well, it will not fall, and this should be the most confusing part of this problem.

Then the snail climbed four zhang in the first four days, and climbed three zhang during the day on the fifth day, and crawled out directly, so the snail actually crawled out of the well in five days! Perfect! I, Li Tai, are really the smartest, hehe! ”

Li Tai showed a smug smile on his face, and he quickly wrote the answer, but inadvertently, he glanced at the hourglass on the podium, and was immediately taken aback, he took nearly a quarter of an hour to ask two questions, and this is still it?

Li Tai glanced at the vast sea of questions behind him, the smug look on his face was no longer there, he took a deep breath, and continued to plunge into the "battle".

"Bell, bell!"

Just when all the students were still immersed in the sea of questions, the gongs and drums of Guozijian's first class had already sounded, and the students were taken aback, they didn't expect time to pass so quickly, at this time, many people didn't even finish the fill-in-the-blank questions, you can imagine how perverted Li Zexuan's questions this time were!

"Oops! It seems that some questions are too difficult and need to be abandoned! ”

Tie Dan had just reached the last question of the fill-in-the-blank question at this time, and he estimated the time required for the remaining questions, and after finding that some of them were not enough, he secretly made a decision.

Smart students all have similar ideas, first easy and then difficult, otherwise they will definitely not get high scores.

……………………

"Passed the test" all the way, of course, they were "cut" many times, but many students finally did the last question and answer, 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, he spent a while writing the answers on the test paper step by step, and then he was about to turn back to do the few questions that he had not done before, but he saw that there was a big question behind him.

"Damn, what kind of medicine did Li Zexuan take! It's too much! ”

Li Tai was almost driven crazy in his heart, but when he saw the words in the parentheses behind the additional question, his heart moved, and he immediately stopped scolding his mother.

"20 points will be added to the total score of correct answers, and no points will be deducted for wrong answers!"

Li Tai turned back to the paper and found that there were four or five questions that he hadn't done before, and they added up to about a dozen points, and now there are less than two quarters of an hour left, and he may not be able to answer all the previous questions correctly, after all, those questions are the most difficult questions he thinks, so it is better to concentrate on the last additional question, and add 20 points if he gets it right.

Li Tai immediately made a decision in his heart, and began to read the last additional question with all his heart.

"There are three people to stay, a night of thirty Wen, three people each paid ten Wen, enough for thirty Wen to hand over to the boss, and then the boss said that today's discount is only twenty-five Wen is enough, take out five Wen and order the inn maid to return it to them, the little guy secretly hid two Wen, and then, the remaining three Wen was distributed to the three people, each of whom received a penny. These three times nine is equal to twenty-seven wen, plus the two wen money hidden by the waiter, it is equal to twenty-nine wen, and where did the other penny go? Why? ”

"Huh~? This question makes a lot of sense, but according to this calculation, where did the penny go? ”

Li Tai is not the only one who found the advantages of additional questions, Sun Zifan also found that on the whole set of test papers, there are only a dozen or so questions, which do not contain Arabic numerals and operation symbols, including this one, and the bonus points are still very high, Sun Zifan fell in love with this question at a glance, but what was said in this question had already wrapped him in, and he didn't know where the penny went!
