A household appliance manufacturer wanted to understand the following questions through market resea

For the area to be supplied, you can conduct a survey in the form of a questionnaire, which can be divided into: 1. The understanding of your product, specifically list the characteristics of the electrical appliances you fancy and inquire (this part can try to imply the advantages of your product and play an advertising role) 2. Consult customer opinions and views on the product, so as to sell the goods appropriately in the future, as well as their own changes.

I have been involved in the research system of such projects for a long time. Beijing Hyundai, Samsung, Zhongke Sanhuan, Toshiba and other companies have been customers of this "system". We hope to have the opportunity to serve your company. See the message I sent to you for details.

Air conditioner output value 1 man-hour = 8,000 yuan 1 man-hour.

Refrigerator output value 1 man-hour = 8,000 yuan 1 man-hour color TV output value 1 man-hour = 9,000 yuan 1 man-hour.

Because 120*1 3=40

Air conditioners and refrigerators must be coordinated for 1 3 man-hours each.

The output value of color TV per unit of man-hour is high, so the minimum value of refrigerator output is 2020*1 4+Air conditioner*1 2=(20+Air conditioner)*1 3 Air conditioner=10

20 refrigerators + 10 air conditioners + 90 color TVs can meet 120 units and 40 working hours, with a total output value of 40 + 40 + 270 = 350 thousand yuan.

Output value per unit of working hours:

Air conditioning: 4 (1 2) =8

Color TV: 3 (1 3) = 9

Refrigerator: 2 (1 4)=8

Color TV is the highest, and in terms of the output value of a single unit, air conditioning is the highest.

Therefore, when the working hours are insufficient, it is necessary to produce as many color TVs as possible, and when there are surplus working hours, it is necessary to produce as many air conditioners as possible, so that all the working hours can be used up, and the output value can be the highest.

Because at least 20 refrigerators need to be produced, it takes 20 * (1 4) = 5 man-hours, so there are 40-5 = 35 man-hours left every week, and 120-20 = 100 sets can be produced to produce all color TVs, then it takes man-hours 100 * (1 3) = 100 3, so there are still man-hours left: 35-100 3 = 5 3

Each air conditioner needs 1 2-1 3 = 1 6 man-hours more than a color TV, so the number of air conditioners that can be made is: (5 3) (1 6) = 10 Therefore, 10 air conditioners, 90 color TVs, and 20 refrigerators are the highest.

The maximum output value is: 10 * 4 + 90 * 3 + 20 * 2 = 350 thousand yuan.

Air conditioning: 4 (1 2) =8

TV: 3 (1 3) = 9

Refrigerator: 2 (1 4) = 8 > TV is the highest, and the air conditioner is the highest from the point of view of a single output value.

Lack of time in working hours, as much as possible to produce color TVs, remaining working hours, as much as possible to produce air conditioners, working hours can be used all in the highest output value you can get.

Because it takes at least 20 * (1 4) = 5 hours to produce, the remaining 40-5 = 35 hours, working 20 refrigerators per week, and also producing 120 -20 = 100

Each one that needs air conditioning is more than 1 2-1 3 = 1 to work for 6 hours, and the number of air conditioners can do: (5 3) (1 6) = 10 units.

So, make 10 air conditioners, 90 color TVs, 20 refrigerators, and the highest output.

The maximum output value is: 10 * 4 + 90 * 3 + 20 * 2 = 350,000 yuan.

The output value x and the time taken by a b c are respectively to obtain the following formula:

f（x）=a+b+c=120

c>=10

Then: f(x)max=10,000 yuan. That is, color TVs are the mainstay, 330 units, air conditioners are not produced, and refrigerators are guaranteed at least 40 units.

Let the growth rate be x

450+450（x+1）+450（x+1)^=1638450(1+x+1+x^+2x+1)=1638x^+

a=1,b=3,c=

b^-4ac=

x= (rounded) x= i.e. x=

1. There is an error in your question: the first "air conditioner" in the third line contradicts the second "air conditioner";

According to common sense, the first "air conditioner" is assumed to be a refrigerator;

2. Answer: The output value of the refrigerator per unit time: 4000 * 2 = 8000 yuan;

Color TV unit time output value: 3000 * 3 = 9000 yuan;

Air conditioning unit time output value: 2000 * 4 = 8000 yuan;

Therefore, the total output value of only producing color TVs is the highest, since there are at least 60 refrigerators, so.

When the maximum output value is 60 refrigerators, the output value is: 60 * 4000 = 240,000.

60* man-hours.

120-30 = 90 man-hours.

90 man-hours to produce color TV, the output value is: 90 * 9000 = 810,000.

The highest total output value is 81 + 24 = 1.05 million yuan, that is, 1050 thousand yuan.

It produced 60 refrigerators, 270 color TVs and 0 air conditioners.

If the number of air conditioners, color TVs, and refrigerators that should be produced per week is x, y, and z respectively, then there are, x+y+z=360

1/2x+1/3y+1/4z=120②

z 60 is obtained from 3x+y=360, and the total output value a=4x+3y+2z=2(x+y+z)+(2x+y)=720+(3x+y)-x=1080-x, z 60, x+y 300, x+360-3x 300, x 30, a 1050

when x=30, y=270, z=60; A = 1050, A: 30,270,60 units of air conditioners, color TVs, and refrigerators should be produced every week to make the output value the highest The highest output value is 1050 thousand yuan

Hello, dear <>

Here, according to the question you provided, we will find the following: Third, Company C's market share is 20%, which is slightly behind Company B, but still occupies a certain market share. Fourth, Company D's market share is 15%, which is slightly behind Company C, but the company still has a competitive position in the market.

Hello, dear <>

According to the questions you provided, we will find the following: Finally, Company E's market share is 10%, although it occupies a certain market share in the category market, but compared with other companies, the company's market position is relatively weak. To sum up, the survey data shows that in the category of Jianchen market, A, B, C, D, and E all occupy a certain market share, but their market position and competitiveness are different.

In response to these differences, companies can further optimize product performance, improve quality, and reduce ** to increase market share and competitiveness.
