Prepare for the GMAT Exam-Test Prep Materials-GMAT 真题训练:Data Sufficiency
题目
How many books does Ricardo have?
(1)If Ricardo had 15 fewer books, he would have only half as many as he actually has.
(2)Ricardo has twice as many fiction books as nonfiction books.
选项
A. Statement (1) ALONE is sufficient but statement (2) ALONE is not sufficient.
B. Statement (2) ALONE is sufficient but statement (1) ALONE is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are not sufficient.
答案:A
解释:From statement (1) it can be concluded that 15 books represent half the total number of books that Ricardo has. Alternatively, if n represents the number of books that Ricardo has, then it follows from (1) that n-15 = (1/2)n, which can be solved for n. Thus (1) alone is sufficient, and the answer must be A or D. Statement (2) alone is not sufficient, since it gives only the ratio of the number of fiction to the number of nonfiction books. Thus, the best answer is A.
