Chapter 298 Finale

  Shen Yu's first reaction was the relevant content about marginal revenue and marginal cost in Western economics.

  Marginal cost refers to the change in the total cost caused by increasing or decreasing a unit of output under a certain output level.

  Marginal revenue refers to the increase in total revenue brought by each additional unit of sales in the production process.

  When the marginal revenue is greater than the marginal cost, the enterprise is profitable and will increase production; otherwise, the enterprise will lose money and reduce production.

   Therefore, when the two reach a balance, that is, when the marginal revenue equals the marginal cost, the enterprise can realize the maximum profit.

  After organizing the language well, Shen Yu no longer hesitated to answer with a pen.

  The relevant knowledge involved in this question is not difficult, as long as you have studied economics courses, you should know it. But the difficulty is that it appears here, not the final exam of the university, nor the completion test of a single course. It is easy for people to ignore the general things directly, and analyze the actual situation, such as rationally carrying out production management and cultivating enterprises. Start with specific aspects such as culture and labor compensation.

  To overgeneralize, taboo!

   After finishing the essay questions, I wrote a lot of words. At first glance, there were two densely packed pages. Only then did Shen Yu feel his hands sore, so he simply put down the pen, kneading and loosening his joints, while flipping through the calculation questions.

  This time, there is no long and cumbersome topic information, but the series of numbers are still not easy to fool.

  An enterprise sells 27,000 units of product A each year, and the price of each unit is 40 yuan, of which 28% are for cash sales, and the rest are for credit sales. Credit terms "3/10, 1/10, N/30". 50% of customers pay within 10 days, 20% within 20 days, 25% within 30 days, and 5% within 30~40 days. If the annual interest rate of securities is 12%. Calculate the opportunity cost of accounts receivable.

  The first question is the knowledge related to intermediate financial management, which is of average difficulty.

  Shen Wei sorted out his thoughts, first performed calculations on the draft paper, and after the results were obtained and confirmed to be correct, they were copied onto the answer sheet.

  Daily credit sales=27000×40×(1—28%)/360=2160 yuan

  Average time between receipts...

  Accounts Receivable Balance…

  Finally, opportunity cost=39960×12%=4795.2 yuan

  The second question is the practical application of overall planning and planning, which is slightly more difficult.

  The third question is all in English, and examines the relevant knowledge of CGA (Canadian Certified Public Accountant).

  The fourth question, the final question, is pure mathematics, and the difficulty refers to IMO.

   I read it specially when I was browsing between Shen and Wang. It is within the scope of trying, but it just takes a little more time.

  A cross divides the grid into four parts. Xiao Ming starts from the middle and tosses two coins at the same time as coordinates to control the direction of progress. Two coins, one red and one yellow, after tossing XX number, which coordinate has the greatest probability of staying? If you return from this point to the starting point, what is the probability?

   Not surprisingly, it is still a probability question.

  Shen Wei has done the real test papers over the years, and found a very interesting pattern, the final questions are more or less related to probability-related knowledge.

  For example, this time, Brownian motion is combined on the basis of probability.

  If you want to solve the problem, you must at least understand what Brownian motion is—the phenomenon of random motion of suspended particles hit by molecules.

  Shen Wei is not a mathematical genius, nor is he well-read enough to know even these professional mathematical theories at his fingertips.

  She just focused on the relevant knowledge of probability before the exam.

   It is more appropriate to say that speculation is not so much due to strength.

   The second update is a bit short, so let’s send it out before midnight, and there’s still a third update. It’s recommended to go to bed first, and watch it when you get up in the morning~
