Year 10
Year 11
Table

At the Moslund Plant, the assembly line consists of 3 conveyor belts. In addition, there are 3 inspection posts, one at the end of each conveyor belt. In Year 10 (Y10), 15 workers were employed directly on the line; 3 of these workers staffed the inspection posts, one at each post.In Y10, the Moslund Plant assembly line had an output of 250,000 units and generated a profit of $15,000,000.

For Year 11 (Y11), the Moslund Plant assembly line was modernized as follows:Conveyor-belt speeds were increased by a fixed percentage.The assembly line’s administrative unit was restructured to maximize efficiency.Each inspection post was automated, and the 3 workers who formerly staffed the posts were laid off and were not replaced.There were no other personnel changes on the assembly line for Y11.

Moslund Plant Assembly Line Modernization, Y11

For a given production year, let Q denote the total output, in assembled units, from the Moslund Plant assembly line, and let N denote the number of workers employed directly on the line. For each of the following statements about the quotient $Q over N$ , select Yes if it is true based on the information provided. Otherwise, select No.

Yes No

Q/N was less than 10000 for Y10.

Q / N was unchanged from Y10 to Y11.

Q / N remained below 30000 in Y10 and Y11.

正确答案： 2,2,1

涉及知识点概述
本题主要涉及比率计算（计算Q/N的值）以及数值比较（与给定数值比较大小，判断不同年份间该比率是否变化）。解析
- 对于“Q/N was less than 10000 for Y10”：已知Y10时，Q = 250000，N = 15，计算Q/N = 250000÷15≈16667＞10000，所以选No。 - 对于“Q / N was unchanged from Y10 to Y11”：由于Y11的Q和N值均未给出，无法确定该比率是否变化，所以选No。 - 对于“Q / N remained below 30000 in Y10 and Y11”：Y10时Q/N≈16667＜30000，但Y11数据缺失，不能确定该比率在Y11也低于30000，所以选No。
