Mr. Quan, please take care

Chapter 298 Finale

Shen Wei'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 at a certain output level.

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

When the marginal revenue is greater than the marginal cost, the company is profitable and will increase production; otherwise, the company 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 maximize its profit.

After Shen Yu organized her words, she 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 rational production management and cultivation of enterprises. Start with specific aspects such as culture and labor compensation.

Overgeneralization, 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.

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

某企业年销售A产品27000台，每台售价40元，其中28%为现销，其余为信用销售。信用条件“3/10，1/10，N/30”。10天内付款的客户占50%，20天内付款的占20%，30天内付款的占25%，30~40天内付款的占5%。若有价证券年利率为12%。计算应收账款的机会成本。

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

Shen Wei sorted out her thoughts, first performed the calculation on the draft paper, and after getting the result and confirming that it was correct, she copied it into the answer sheet.

每日信用销售额=27000×40×（1—28%）/360=2160元

The average time between receipts...

Accounts Receivable Balance...

Finally, opportunity cost = 39960 × 12% = 4795 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 finale question, is pure mathematics, and the difficulty refers to IMO.

When Shen Yu was browsing, I looked at it specially, and it was within the scope of trying, but it would take 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 question of probability.

Shen Wei has done the real test papers over the years and found a very interesting pattern. The final questions all involve more or less 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 genius in mathematics, nor is he well-known enough to know that even these professional mathematical theories can be mastered 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 zero o’clock, 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~
