gmat数学真题及解析答案详解

gmat数学真题及解析答案详解GMAT数学真题及解析答案详解GMAT（全球管理硕士研究生入学考试）是一个非常重要的考试，它对于想要进入顶尖商学院深造的学生来说至关重要。

GMAT考试包括四个部分，其中数学部分是很多考生担心的一部分。

本文将介绍一些GMAT数学真题，并给出详细的解析答案，帮助考生更好地准备考试。

题目一：The cost, in dollars, of producing x units of a certain commodity is given by the equation C = mx + b, where m and b are constants. If the cost of producing 50 units is $1800 and the cost of producing 100 units is $2800, what is the cost of producing 150 units?解析：首先，根据题目中的信息，我们可以得到两个方程：1800 = m(50) + b2800 = m(100) + b我们需要求解的是当x=150时的C的值。

为了求解这个问题，我们需要求解m和b的值。

我们可以使用第一个方程来求解m和b的值：1800 = m(50) + b2800 = m(100) + b我们可以通过减去两个方程得到：1000 = m(50)因此，m的值为20。

将m的值带入第一个方程，我们可以求解b 的值：1800 = 20(50) + bb = 1800 - 1000b = 800现在，我们可以使用C = mx + b的方程来计算当x=150时的C的值：C = 20(150) + 800C = 3000 + 800C = 3800因此，当生产150个单位时的成本为3800美元。

题目二：The average (arithmetic mean) of 7 numbers is 10. If one of the numbers is removed, and the average of the remainingnumbers is 9, what is the value of the number that was removed?解析：让我们假设被移除的数字为x。

请在屏幕下方的方框内作答。

下面的文章摘自一个有名的娱乐杂志的专栏：如果即将上映的电影3003的制作人肯花重金让Robin Good在其中参演的话，他们的利润将会达到一个最大化，即使这笔重金的花费比整个电影的其他参与人员的费用总额还要高。

毕竟，Robin在过去很多电影中都是被重金聘请，并且这些电影都有很成功的票房。

讨论你在多大程度上同意或反对这个观点。

用自己的经验、观察或阅读知识来支持你的观点。

3. 数学Quantitative 37道题，75分钟内完成题目说明：在数学部分，你会遇到两种题目：问题解决和数据充分性。

对于每道问题解决题来说，你需要解决所给定的数学题并且在5个答案中选择一个正确答案。

（相当于我们的数学考试里的选择题）；对于数据充分性题目来说，题目会包含一个问题和两个陈述（1）和（2），用这两个条件和相应的数学知识来看这两个条件对于解决给出的问题是否充分有效（能否用条件算出问题的结果），这种题目的5个选项永远是相同的，即：A 陈述（1）单独是充分的，但是陈述（2）单独不充分B 陈述（2）单独是充分的，但是陈述（1）单独不充分C 两个陈述合在一起是充分的，但是单独的陈述哪一个都不充分D 每一个陈述单独都是有效的E 陈述（1）和陈述（2）合在一起都是不充分的例如：在三角形PQR里，x的值是什么？（1）PQ=PR（2）y=40解答：从陈述（1）可知，PQR是等腰三角形，所以y=z；而三角形内角和为180°，所以x+y+z=180°，也就是x+2y=180°，但是因为陈述（1）并没有说明y的值是什么，所以求不出x的值，所以陈述（1）单独不有效；在陈述（2）中，y=40可得出x+z=140，因为陈述（2）并没有说明z的值，所以也求不出x的值，所以陈述（2）单独不有效；但是把两个陈述合在一起，我们就知道，x+2y=180，y=40，那么x的值自然就求出来了，所以答案应该选C ，两个陈述合在一起是充分的，但是单独的陈述哪一个都不充分。

正式题目：1、一个计划的财年计划预算是12600美元，平均分配到12个月，在该财年第四个月的末尾处，这个计划一共花了4580美金，问这个计划超出了预算多少钱？(A) $ 380(B) $ 540(C) $1,050(D) $1,380(E) $1,4302、对于每个正偶整数n，函数h(n)被定义为从2到n的所有偶整数的乘积，包含2和n。
