问题 Now that you’ve gotten a little more confident, we’re going to give you the opportunity to practice "without the training wheels." When you want to check your work, you can turn to the solutions at the end. If you aren’t familiar with some of the mathematical concepts, make a note to pay particular attention to that chapter in this book; this practice set covers a wide range of topics tested on the GMAT.
   On all data sufficiency problems, the answer choices are the same (as you’ve learned). We’ve put them here for your reference.
   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.
What is the value of v/w?
   (1) w/v=-1.5
   (2) v>0

选项

答案A

解析 Statement (1) tells us the value of the reciprocal of v/w…-1.5 or -3/2. That means v/w has to equal -2/3, so statement (1) is sufficient and we can eliminate B, C, and E.
   Statement (2) alone tells us nothing about w and very little about V, so it is not sufficient. A is our answer.
