是OG里面的数学样板题,大家应该都看过这道题,里面有这句话:“and there are more than twice as many employees in Department X as in Department Y.” 我每次做题总是理解错,正确的翻译是不是应该是X>2Y?
请教一下英语比较扎实的同学,关于比较级的形容,这句话应该怎么分析? 可不可以给一些指点呢?谢谢!
这个周末就考G了,希望数学可以170。也祝大家可以争取到理想的OFFER!!

下面附上原题:
Each employee of a certain company is in either Department X or Department Y, and there are more than twice as many employees in Department X as in Department Y. The average (arithmetic mean) salary is $25,000 for the employees in Department X and is $35,000 for the employees in Department Y. Which of the following amounts could be the average salary for all of the employees in the company?
Indicate all such amounts.
􏰔A $26,000
􏰔B $28,000
􏰔C $29,000
􏰔D $30,000
􏰔E $31,000
􏰔F $32,000
􏰔G $34,000
选AB============================================
补充一下,各位回复的大神,解题过程就不用回复啦,具体方法会做。
发帖目的是想问“and there are more than twice as many employees in Department X as in Department Y.” 这句话怎么翻译,为什么我觉得就是Y>2X呢???

salary of X> 2*(salary of Y), Answer:Avg(salary)<(25000*2+3000)/3==>A,B.

谢谢你的回复,具体的解答部分我是会的,现在就是那句话没看懂“and there are more than twice as many employees in Department X as in Department Y.”

我总是理解成Y>2X。。。怎么办呢。。
