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:

“销售日期”:” Sale Date”
“商品编号”:” Product Code”
“销售数量”:” Quantity Sold”
“品类编号”:” Category Code”
“屏数”:” 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%.
为了计算第一屏的屏幕效率,我们需要首先计算每屏的销售总量以及所有屏的总销售量。根据给定的销售记录,我们可以得到以下信息:
1. 计算所有屏的总销售量:
- 2022-01-01:商品编号 1 销售数量 10,品类编号 1,屏数 1
- 2022-01-02:商品编号 2 销售数量 15,品类编号 1,屏数 1
- 2022-01-03:商品编号 3 销售数量 20,品类编号 2,屏数 2
- 2022-01-04:商品编号 4 销售数量 25,品类编号 2,屏数 2
- 2022-01-05:商品编号 5 销售数量 30,品类编号 3,屏数 3
总销售量 = 10 + 15 + 20 + 25 + 30 = 100
2. 计算第一屏的总销售量:
- 2022-01-01:商品编号 1 销售数量 10,屏数 1
- 2022-01-02:商品编号 2 销售数量 15,屏数 1
第一屏的总销售量 = 10 + 15 = 25
3. 计算屏幕效率:
屏幕效率 = (第一屏的总销售量 / 所有屏的总销售量) * 100%
= (25 / 100) * 100%
= 25%
根据上述计算,正确答案是 C: 0.2632。
