一道GRE数学题，求详解

A certain scholarship committee awarded scholarships in the amounts of $1,250, $2,500, and $4,000. The committee awarded twice as many $2,500 scholarships as $4,000 scholarships, and it awarded three times as many $1,250 scholarships as $2,500 scholarships. If a total of $37,500 was awarded in $1,250 scholarships, how many $4,000 scholarships were awarded?

(A) 5
(B) 6
(C) 9
(D) 10
(E) 15
答案选A

Answer 1

选e
题目是Mark就职于一家有80人的公司，每个人的工资各不相同。Mark现在是第一分位中第二高的。如果公司此时再聘用8名新员工，并且他们的工资比以前所有人的工资都要低。问现在88人中，Mark的工资排在什么位置上？
解答：之前，Mark排在 80/4-1=19位，现在19+8=27位，88/4=22,27-22=5,所以是第二分位倒数第五。

Answer 2

答案选A，题目的意思是，1250的授奖次数是2500的三倍，2500的授奖次数是4000的二倍，已知条件是1250授奖总金额37500，也就是授奖30次，那么可以推算出2500是10次，4000是5次。
