Chapter Thirty-Two His answer was correct

  Lin Feng continued to calculate the second question, and soon got the answer that there were 23 chickens and 34 ducks. The staff said again "His calculated answer is correct", then Lin Feng went on to calculate the third question...

  These questions are all applications of binary linear equations, and for Lin Feng, they are just a piece of cake. In less than five minutes, Lin Feng had finished the first five easiest questions.

  Compared to Lin Feng's calmness, the crowd felt numb, and the staff's repeated words "His calculated answer is correct" had already shocked them into a daze, staring blankly at Lin Feng who was lost in thought.

  What the hell? Some of us have been calculating for days and still can't figure it out, but you managed to solve it in less than five minutes. Are you even human?

  However, by the sixth question, Lin Feng's speed slowed down. One minute had passed and Lin Feng still hadn't calculated the answer, which made them slightly relieved, finally having time to catch their breath.

  The topics of questions 6 to 9 are all ternary linear equations, which are more cumbersome, but Lin Feng still has a way to solve them.

  What kind of question made Lin Feng slow down?

  There were three people, Xiaojun, Xiaohong and Xiaohua. The sum of their ages was 35. Twice Xiaojun's age minus five is equal to Xiaohong's age. Twice Xiaohong's age equals three times Xiaohua's age. What are the ages of Xiaojun, Xiaohong and Xiaohua?

  Everyone felt dizzy after seeing these numbers. Why is it an age problem again? Looking at Lin Feng again, he was seen writing silently on the paper,

  "Xiao Jun: x; Xiao Hong: y; Xiao Hua: z."

  "x + y + z = 35, 2x - y = 5, 2y = 3z. Solving the three equations simultaneously yields x = 10, y = 15, z = 10. Therefore, Xiao Jun, Xiao Hong and Xiao Hua are 10 years old, 15 years old and 10 years old respectively."

  This question took Lin Feng a whole two minutes, after all, it was a cubic equation, and solving it wasn't that easy.

  "Ah, everyone look, he's calculated it again!" someone exclaimed, and the crowd once again turned their attention to the staff member. The staff member was both helpless and shocked at the same time - this was already the sixth question, and its difficulty was many times higher than the previous five questions. He couldn't believe that the other person could still calculate it so quickly.

  His calculated answer is correct.

  The voice contained a hint of helplessness and admiration, and as soon as everyone heard it, they suddenly burst into astonishing applause.

  "Wow, I didn't think he was right again!"

  "Yes, it took a bit more time this time, but just one more minute. One minute, and the problem that's been difficult to solve for who knows how many times was solved."

  "But anyway, what's with the x, y, z symbols? It seems like he was using these symbols to calculate the answers before. Why have I never heard of this font before?"

  ．．．．．．

  As he said this, everyone had an expression of confusion on their faces.

  At this moment, Qin Yong almost vomited blood. He originally thought that Lin Feng was just lucky to get the answer to the first question right, but unexpectedly, he got the answers one after another, and now he has already gotten the sixth question right, with only three questions left. From the first question to now, it's been only seven minutes! There are still twenty-three minutes left until the time he said, will Lin Feng be able to finish these last three questions in twenty-three minutes? Even he himself didn't believe it.

  The last three questions were basically the same, Lin Feng used less than nine minutes to get all the answers correct, and everyone was stunned again. The only sound left in the field was the staff's voice "His answer is correct".

  In less than a minute, Lin Feng perfectly solved the nine questions, and this result shocked everyone present. At first, they thought Lin Feng was just boasting, wondering how it was possible for someone to answer these nine difficult questions in half an hour?

  But the fact gave them a hard slap in the face, letting them know that there is a sky outside the sky and a person outside the person. This world still has such people who create miracles!

  Qian Feihua looked at Lin Feng, who was full of vigor and spirit, and felt a deep sense of emotion. He had originally thought that this young man's words were just boasts, the result of youthful arrogance and a desire to compete. But he hadn't expected that his opponent would actually be able to do it, and with such perfection, leaving no room for criticism.

  At the thought of this, I couldn't help but sigh. It seems that I've grown old and become somewhat stubborn, thinking that just because someone is young, they're not as good as me.

  Zhao Jiansheng was also staring blankly at Lin Feng, as if he couldn't believe that Lin Feng had solved the nine difficult problems so simply!

  "Boom"

  Just then, a dull sound broke the strange scene, and everyone looked up to see a huge white cloth suddenly pouring down from the roof, covering most of the previous strips. On this huge white cloth was written:

  "A antique shop sells a batch of antiques, with an average daily sales volume of 20 pieces, and a profit of 40 taels of silver per piece. In order to expand sales and increase profits, the shopkeeper decides to take appropriate price reduction measures to quickly reduce inventory. After investigation, it is found that if each antique is reduced by one tael, the market can sell two more pieces per day. If the average daily profit of the store is 1200 taels of silver, how many taels should each antique be reduced?"

  Lin Feng couldn't help but be shocked again, damn it, isn't this an application of the quadratic equation in another world?

  No wonder it was placed at the last question, this question is much more difficult than any of the previous ones, even he estimated that he would have to spend some effort on this question, and quickly took another piece of paper, hastily writing in silence.

  "Each antique should be discounted by two silver coins."

  "According to the question, (40-x)(20+2x)=1200 is obtained. After sorting, x^2-30x+200=0 is obtained. Solving it gives x1=10 and x2=20. Since the question requires reducing inventory as soon as possible, x takes 20, so each antique should be reduced by 20 taels of silver."

  This question took Lin Feng a full ten minutes, far exceeding the time he had spent on previous questions, but fortunately, he finally calculated it out.

  But just as Lin Feng calculated it out in an instant, someone beside him suddenly exclaimed.

  "Ah, Lin Feng has calculated it again, and the answer is twenty taels of silver."

  Everyone looked at the staff member with eager eyes, filled with expectation. Would someone finally get the ultimate reward of a six-month period this time?

  All that was seen was the staff member reaching into his pocket and pulling out a black box, opening it to reveal a piece of paper with the answer to the final question on it, which even he didn't know. After glancing at it, his face showed some excitement, his hands slightly trembling as he stammered, "His...his answer is...is correct."

  Wow!

  Everyone cheered as if the one who answered all the questions was themselves. The sound echoed across the entire sky...

  (Update 2 is online, there should be another one tonight, thanks for your support, everyone, your votes are correct for me........)
