各位要参加2020年GMAT考试的小伙伴们注意啦！今天帮考网要给各位小伙伴分享2020年GMAT考试《GMAT数学》的每日一练，感兴趣的小伙伴赶快来看看哦！

一、If the population of a certain country is 120,256,000 and its land area is 2,998,000 square kilometers, then the population per square kilometer is closest to which of the following?

A、 4

B、 6

C、 20

D、 40

E、 60

正确答案：D

解题思路：

很简单的一道计算题，但在不使用计算器的情况下可以通过四舍五入的方式更快得到答案。前一个数字简化为120，后一个数字简化为3，相除为40，答案为D。

二、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。

三、A solid yellow stripe is to be painted in the middle of a certain highway. If 1 gallon of paint covers an area of p square feet of highway, how many gallons of paint will be needed to paint a stripe t inches wide on a stretch of highway m miles long? (1 mile = 5,280 feet and 1 foot = 12 inches)

A、 5280mt/12p

B、 5280pt/12m

C、 5280pmt/12

D、 5280*12m/pt

E、 5280*12p/mt

正确答案：A

解题思路：

在一条高速公路上画一道黄线，一加仑颜料能够画p平方英尺的面积，求问需要多少加仑颜料才能画一条宽度为t英寸，长度为m英里的黄线。

本题的解题要点在于单位换算上，由于题目本身已经给出了换算数据，因此按照总面积除以一加仑面积就能得出加仑数。也就是宽度t/12乘以长度m*5280再除以p。得出算式为5280mt/12p，也就是答案A。
