GRE数学考试真题及解析(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.

　　解析

　　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。
