问题 At Megalomania Industries, factory workers were paid $20 per hour in 1990 and $10 per hour in 2000. The CEO of Megalomania Industries was paid $5 million per year in 1990 and $50 million per year in 2000. The percent increase in the pay of Megalomania’s CEO from 1990 to 2000 was what percent greater than the percent decrease in the hourly pay of Megalomania’s factory workers over the same period?
选项 A、850％
B、900％
C、950％
D、1700％
E、1900％
答案D
解析 本题信息量大，问题描述复杂，因此要对信息进行有效的整理，建议在草稿纸上列出必要的信息。1990年和2000年，工人和CEO的工资信息：

第三句话是题目的问题：(The percent increase in the pay of Megalomania’s CEO from 1990 to 2000 was what percent greater than the percent decrease in the hourly pay of Megalomania’s factory workers over the same period?)提取句子的主干是A was what percent greater than B，对应表达式(A-B)/B。这里的A是“The percent increase in the pay of Megalomania’s CEO from 1990 to 2000”，即CEO从1990年到2000年工资增长的百分比，对应表达式A=|5-50|/5×100％=900％。这里的B是“the percent decrease in the hourly pay of Megalomania’s factory workers over the same period”，即工人在同一段时间(从1990年到2000年)工资下降的百分比，对应表达式B=|20-10|/20×100％=50％。将A和B代入|A-B|/B×100％=|900％-50％|/(50％)×100％=1700％，选择D选项。
