The products are sold on an e-commerce platform, with a total of 5 categories introduced, encompassing 20 different items. Each screen can display 5 product slots. The sales records for these 5 days are as follows:
Primary Chinese-English Correspondence
“銷售日期”：” Sale Date”
“商品編號(hào)”：” Product Code”
“銷售數(shù)量”：” Quantity Sold”
“品類編號(hào)”：” Category Code”
“屏數(shù)”：” Screen Count”
Assuming screen efficiency = total sales quantity of all products within a screen / total sales volume of all screens * 100%, what is the screen efficiency for the first screen?
The sales quantity for the first screen is 4, and the total sales volume for all screens is 19. Therefore, the screen efficiency for the first screen is 4/19 * 100% = 21.05%.
為了計(jì)算第一屏的屏幕效率，我們需要首先計(jì)算每屏的銷售總量以及所有屏的總銷售量。根據(jù)給定的銷售記錄，我們可以得到以下信息：
1. 計(jì)算所有屏的總銷售量：
- 2022-01-01：商品編號(hào) 1 銷售數(shù)量 10，品類編號(hào) 1，屏數(shù) 1
- 2022-01-02：商品編號(hào) 2 銷售數(shù)量 15，品類編號(hào) 1，屏數(shù) 1
- 2022-01-03：商品編號(hào) 3 銷售數(shù)量 20，品類編號(hào) 2，屏數(shù) 2
- 2022-01-04：商品編號(hào) 4 銷售數(shù)量 25，品類編號(hào) 2，屏數(shù) 2
- 2022-01-05：商品編號(hào) 5 銷售數(shù)量 30，品類編號(hào) 3，屏數(shù) 3
總銷售量 = 10 + 15 + 20 + 25 + 30 = 100
2. 計(jì)算第一屏的總銷售量：
- 2022-01-01：商品編號(hào) 1 銷售數(shù)量 10，屏數(shù) 1
- 2022-01-02：商品編號(hào) 2 銷售數(shù)量 15，屏數(shù) 1
第一屏的總銷售量 = 10 + 15 = 25
3. 計(jì)算屏幕效率：
屏幕效率 = （第一屏的總銷售量 / 所有屏的總銷售量） * 100%
= (25 / 100) * 100%
= 25%
根據(jù)上述計(jì)算，正確答案是 C: 0.2632。
