分析数据并得出结论
GMAT™考试的定量推理部分考核你进行定量推理、解决量化问题和诠释图表数据的能力。本部分共31道多选题，总答题时间为62分钟。
定量推理部分的两种题型
定量推理部分有两种题型，即：问题求解和数据充分性分析。这两种题型均需要一定的算术知识、初等代数知识和几何常识。请放心，试题的难度源于所需的逻辑和分析技能，而非以此为基础的数学技能。请注意，回答定量推理部分试题时不能使用计算器。
问题求解
- 衡量你运用逻辑和分析推理解决量化问题的能力。
- 你需解决问题并指出五个答案中的最佳答案。
数据充分性分析
- 衡量你分析量化问题、识别数据的相关性，并确定在何种程度上具有能解决问题的充分数据的能力。
- 试题包括一个问题和两条陈述。你可利用陈述中的数据、结合数学知识和日常事实，判定陈述中的数据是否足以解答试题。
测定你的定量推理技能

Sample Data Sufficiency Question
Directions
This data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise), you must indicate whether:
- Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
- Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
- BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
- EACH statement ALONE is sufficient to answer the question asked.
- Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
Question
If a real estate agent received a commission of 6 percent of the selling price of a certain house, what was the selling price of the house?
(1) The selling price minus the real estate agent’s commission was $84,600.
(2) The selling price was 250 percent of the original purchase price of $36,000.
(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.
Answer: (D)
