A telephone company has no.'s between 3000-3799.A Company called X uses the numbers from 3300-3499.Out of these managers of Division1 level use numbers ending with 0 or 1.What percent of the telephone company numbers are used by
Managers of Division1 level of Comany
Managers of Division1 level of Comany
3300~3499尾数为0或者1的一共有2x20=40个,所以比例是40/800=5%
再问: 为什么不是40/200,题中已经说了是在3300-3499中取数啊。
再答: 题目是这样问的What percent of the telephone company numbers are used by Managers of Division1 level of Comany X? 因此Managers of Division1 level of Comany X使用的号码数量是分子,也就是40. 而telephone company numbers是分母,即800,所以是40/800 如果问题换成这样What percent of the telephone company numbers are used by Comany X? 那么应该按照你说的算,因此这里的3300-3499是为了计算40用,同时也是为了模糊考生,做GRE数学细心审题就没有问题了,这道题确实有一定难度,希望能帮到你,加油吧!
再问: 应该是What percent of Company x numbers are used by Managers of Division1?吧
再答: 嗯嗯,对的,我也粗心了 呵呵
