众所周知,新GRE数学难度会随第一个section的准确率而相应的提高难度。为了考生们能有把握拿到满分,下面是为大家列举的新GRE数学疑难问题。
1.从2 3 4 5 6 7 8 9中取数字组成三位数号码,assign to 330 employee, 数字不重复, 问多少号码unassigned?解:P==336336-330=6
2.一个工作W,X做要比Y做少两天,X,Y一起做4/3W要3天,求X单独做2W要几天?解:令W/X=x,W/Y=y,则x+2=y /=3 两式连立化去y,即可解得x
3.=2^x3^y5^z 代表的是n的函数,x,y,z,都是positive integer, and x,y,z,分别代表n的百位,十位和个位,问如果f=9f,m-v=?解:因为f=9f,所以两数百位个位都相同,令a为m的十位,b为n的十位则可知,/=9解得a-b=2所以m-v=210=20
4.10的n次方减38所得数的digit sum 为350. n=?解:9+=350
5.1到n是连续整数, 1到n 数的乘积能被990 整除, 问n 最少是?解:990=11109,所以n不能小于11
以上便是新GRE数学常见的疑难问题以及解答,希望考生在看完之后能在新GRE数学上有所提高!
