今日练习题为数学题，题目如下

In June 1989, what was the ratio of the number of sales transactions made by

Salesperson X to the number of sales transactions made by Salesperson Y?

(1) In June 1989, Salesperson X made 50 percent more sales transactions than

Salesperson Y did in May 1989.

(2) In June 1989, Salesperson Y made 25 percent more sales transactions than

in May 1989.

A Statement (1) ALONE is sufficient, but statement (2) alone is not

sufficient.

B Statement (2) ALONE is sufficient, but statement (1) alone is not

sufficient.

C BOTH statement TOGETHER are sufficient, but NEITHER statement ALONE is

sufficient.

D EACH statement ALONE is sufficient.

E Statements (1) and (2) TOGETHER are NOT sufficient.

正确答案：

C

解题思路：

本题的出题点在于对数学题完全文字化后的转化理解能力和对月份细节的注意上。

这道题求6月销售员X和Y之间销售额的比值。

条件1：销售员X在6月的销售额比销售员Y在5月的销售额多50%。

条件2：销售员Y在6月销售额比自己在5月的销售额多25%。

两个条件单独看都无法得出X和Y之间在6月的直接比值。但结合在一起则可以间接的计算出来。因此选择C。
