Graduate Management Admission Test (GMAT) Quantitative Section ? In the math section, you will have 75 minutes to answer 37 questions: ? A of these question are experimental and would not be counted toward your score. There is no way to identify which questions are experimental as they one mixed in randomly through out the section. ? This section includes two types of questions: Problem solving and Data sufficiency. ? For each problem solving section, you are to solve the problem and indicate the best of the answer choices given. ? For each data sufficiency question, you are to decide whether the information given in each of two statements, labeled (1) and (2), is sufficient to answer the question, whether the information in the two statements together is sufficient, or if neither is sufficient. ? More detailed dissection will appear before the first occurrence of each question type. At any point in the test, you can read the direction for the question type you working on by clicking on HELP. Quantitative Section Time: Solve the problem and indicate the best answer choices given. Number: All the numbers used are Real Numbers Figure: A figure accompanying used a problem solving is intended to provide information useful in solving the problem. Figures are drawn as accurately as possible EXCEPT when it is started in a specific problem that its figure is not drawn to scale. Straight lines may some times appear jagged. All figure lie in a plane unless otherwise indicated.

Question1 If –2<a<11 and 3<b<12, then which of the following is NOT true? (A) 1<a+b<23 (B) -14<a-b<8 (C) -7<b-a<14 (D) 1<b+a<23 (E) -24<ab<132 Question 2 a , b , and c are integers and a < b c . S is the set of all integers from a to b , inclusive. Q is the set of all integers from b to c , inclusive. The median of set S is (3/4) b . The median of set Q is (7/8 )c. If R is the set of all integers from a to c , inclusive, what fraction of c is the median of set R ? (A) 3/8 (B) 1/2 (C) 11/16 (D) 5/7 (E) 3/4 Question 3 a b, and c are positive integers. If a, b , and c are assembled into the six-digit number abcabc which one of the following must be a factor of ? (A) 16 (B) 13 (C) 5 (D) 3 (E) none of the above Question 4 The average of (54,820) 2 and (54,822) 2 = (A) (54,821) 2 (B) (54,821.5) 2 (C) (54,820.5) 2 (D) (54,821) 2 + 1 (E) (54,821) 2 – 1 Question 5 A certain club has exactly 5 new members at the end of its first week. Every subsequent week, each of the previous week's new members (and only these members) brings exactly x new members into the club. If y is the number of new members brought into the club during the twelfth week, which of the following could be y ? (A) (B) (C)
(D) (E) Question 6: DATA SUFFICIENCY PROBLEM Directions: The 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 counterclockwise), you must indicate whether Choice: A
