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

Answer 1

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.
