Shen Hou's first reaction was related to the marginal revenue and marginal cost in Western economics.
Marginal cost refers to the amount of 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 company is profitable and will increase output; otherwise, the company will incur losses and reduce output.
Therefore, when the two reach a balance, that is, when the marginal revenue equals the marginal cost, the enterprise can maximize profits.
After Shen Hou organized the language, he no longer hesitated, and answered with a pen.
The relevant knowledge involved in this question is not difficult, as long as you have studied economics, you should know it. But the difficulty is that it appears here. It is not a final exam for a university or a final test for a single course. It is easy for people to ignore the generality and analyze the actual situation, such as rational production management and enterprise training. Start with specific aspects such as culture and pay attention to labor.
Take a partial generalization, taboo!
After finishing the essay questions, I wrote a lot of words. At first glance, the two densely packed pages felt sore in his hands. He simply put the pen on, kneading and loosening the joints while flipping through the calculation questions.
This time, there is no long-winded topic information, but the series of numbers are still not easy to fool.
A company sells 27,000 units of A product each year at a price of 40 yuan, 28% of which are sold on the spot and the rest are sold on credit. Credit terms "3/10, 1/10, N/30". Customers who pay within 10 days account for 50%, those who pay within 20 days account for 20%, those who pay within 30 days account for 25%, and those who pay within 30-40 days account for 5%. If the securities have an annual interest rate of 12%. Calculate the opportunity cost of accounts receivable.
The first question is related to intermediate financial management knowledge, the difficulty is average.
Shen Wei clarified his thoughts, first performed calculations on draft paper, obtained the results and confirmed that they were correct, then copied them onto the answer sheet.
Daily credit sales=27000×40×(1-28%)/360=2160 yuan
Average time between collections...
Account 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 in English, to examine the relevant knowledge of CGA (Canadian Certified Public Accountant).
The fourth question, the final question, is pure mathematics, and the difficulty refers to IMO.
When I browsed between Shen and Hou, I saw it specially. It is within the scope of the trial, but it takes a little more time.
A cross divides the grid into four parts. Xiao Ming starts from the middle while tossing two coins as coordinates to control the forward direction. Two coins, one red and one yellow. After throwing XX, which coordinate has the greatest probability of staying? What is the probability of returning from this point to the starting point
Not surprisingly, it is still a probability question.
Shen Hou has done the actual test papers over the years and found a very interesting rule. The final questions 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 Hou is not a genius in mathematics, and he is not well aware that even these professional mathematical theories can be easily grasped.
She just focused on the related knowledge of probability before the exam.
It is more appropriate to say that speculation is more appropriate than strength.
