为了便于备考GRE数学真题+答案解析分享，大家可以通过对以下题目进行练习来了解一下GRE数学部分的考试难度。
1、When the even integer n is divided by 7, the remainder is 3.
Quantity A：The remainder when n is divided by 14.
Quantity B：10
A. Quantity A is greater.
B. Quantity B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the information given.
答案：C
解析：因为该数为偶数，而余数为3，因此商与除数的乘积必为奇数，因此商必为奇数。设商为2k+1(k为大于等于零的整数)，则该偶数可表示为7(2k+1)+3，化简，得14k+10.因此余数必为10。
2、 P, Q, and R are three points in a plane, and R does not lie on line PQ. Which of the following is true about the set of all points in the plane that are the same distance from all three points?
A. It contains no points.
B. It contains one point.
C. It contains two points.
D. It is a line.
E. It is a circle.
答案：B
解析：两条相连线段的中线只有一个焦点，到P和Q两点相同的点必定PQ的垂直平分线上， 到P和R两点相同的点也必定在PR的垂直平分线上，由于R不在PQ上，说明PQ的垂直平分线和PR的垂直平分线不平行，相交于一点，这一点到这PQR三点的距离相等，其实就是确定了一个圆心，不在一条直线上的三点确定一个圆。
3、 If the product of 7 consecutive integers is equal to the median of the integers, what is the least of the 7 integers?
答案：-3
解析：这个题要多思考，连续7个整数的乘积是中数，则中数一定是0，这样乘积也是0。然后再根据
consecutive倒推，得知最小的数字是-3。
4、 In a data set of 10,000 numbers varying from 20 to 80, the number 62 is the 60th percentile and the number 74 is the nth percentile.
Quantity A：n
Quantity B： 70
A. Quantity A is greater.
B. Quantity B is greater.
C. The two quantities are equal.
D. The relationship cannot be determined from the information given.
答案：D
解析：注意这个题没有说这10000个数字是均匀分布的，所以nth 和70的大小是无法比较的。
5、 If the product of 7 consecutive integers is equal to the median of the integers, what is the least of the 7 integers?
答案：-3
解析：
这个题要多思考，连续7个整数的乘积是中数，则中数一定是0，这样乘积也是0。然后再根据consecutive倒推，得知最小的数字是-3。
