GMAT的数学部分有两种多选题型——PS(问题求解)和DS(数据充分性判断),考小学到高中学的数学知识的一部分,包括数的四则运算、奇偶性、整除、余数特征、集合、排列组合概率、代数式、解方程、解不等式、简单应用题、简单几何体等等。
我们来看一道例题:
List T consists of 30 positive decimals, none of which is an integer, and the sum of the 30 decimals is S.The estimated sum of the 30 decimals, E, is defined as follows. Each decimal in T whose tenths digit is even is rounded up to the nearest integer, and each decimal in Twhose tenths digit is odd is rounded down to the nearest integer; E is the sum of the resulting integers. If -Iof the decimals in Thave a tenths digit that is even, which of the following is a possible value of E- S?
I. -16
II. 6
III. 10
(A) I only
(B) I and II only
(C) I and III only
(D) II and III only
(E) I, II, and III
答案:B
怎么样,觉得难吗?你做对了吗?
