2、is greater;(B)if Quantity B is greater;(C)if the two quantities are equal;(D)if you cannot determine the relationship based on the given information.10 11 What was the total percent change of Company Xs value from the start of 2007 to the start of 2010? （ A） -4.86% （ B） -4.9% （ C） -4.96% （ D） -5% （
3、E） -5.1% 11 Medals awarded to the 10 highest-ranked countries in the Winter Olympics in Torino, Italy, in 2006 were as shown:12 How many more medals did Germany win than Korea? 13 What is the ratio of bronze to gold medals earned by Italy and France combined? 14 What percentage of all of the medals
4、earned by the top 5 of these countries were silver medals? GRE（ QUANTITATIVE）图表与数值比较模拟试卷 1答案与解析 【知识模块】 数值比较 1 【正确答案】 D 【试题解析】 The correct answer is D. The values of p and r are not given, so you cannot determine the relationship between Quantity A and Quantity B. 【知识模块】 数值比较 2 【正确答案】 B 【试题解析】 The co
5、rrect answer is B. To solve this problem, simplify the equation: 10x = 20 x=2 Quantity B is greater than Quantity A. 【知识模块】 数值比较 3 【正确答案】 B 【试题解析】 The correct answer is B. A negative number raised to an odd power is negative. A negative number raised to an even power is positive. Therefore, Quantity
6、 A is negative and Quantity B is positive. 【知识模块 】 数值比较 4 【正确答案】 A 【试题解析】 The correct answer is A. To solve this problem, simplify the second equation, as follows: y+12 = 23 y=11 Now substitute 11 for y in the first equation: x+11 = 27 x=16 Quantity A is greater than Quantity B. 【知识模块】 数值比较 5 【正确答案】
7、 A 【试题解析】 The correct answer is A. To solve this problem, first determine that there are 180 seconds in 3 minutes. You are given that the windmill makes 8 revolutions in 3 minutes; divide 180 by 8 to get 22.5, which is less than 23. Therefore, Quantity A is greater than Quantity B. 【知识模块】 数值比较 6 【正确
8、答案】 C 【试题解析】 The correct answer is C. Since the triangle is a right triangle, the two smaller angles must total 90. 90-47 = 43. So a = 43, and the quantities are equal. 【知识模块】 数值比较 7 【正确答案】 D 【试题解析】 The correct answer is D. Even though you can calculate how many women and men purchased tickets, you
9、have no information about how many tickets each individual purchased. Therefore, you do not have enough information to determine the relationship between the quantities. 【知识模块】 数值比较 8 【正确答案】 D 【试题解析】 The correct answer is D. You are not given the relationship between the scores. For example, if Geor
10、ge scored an 88 and Mark scored an 87, then Quantity B would be greater. However, if George scored a 90 and Mark scored a 30, then the two quantities would be equal. Therefore, the relationship cannot be determined from the information given. 【知识模块】 数值比较 9 【正确答案】 C 【试题解析】 The correct answer is C. Yo
11、u are given that the area of the square is 64, which means that each side must be , or 8(remember, the area of a square is equal to s2). Therefore, the perimeter of the square is 8 x 4, or 32, making the quantities equal. 【知识模块】 数值比较 10 【正确答案】 B 【试题解析】 The correct answer is B. To calculate 15% of 30
12、 multiply 30 by .15: 30.15 = 4.5 You can use logic to determine that Quantity B is greater: = 5, so must be greater than 5. 【知识模块】 数值比较 【知识模块】 图表 11 【正确答案】 C 【试题解析】 The correct answer is C. The value did not change in 2007, lost 4% in 2008, and lost 1% in 2009. Thus the ending value was 0.960.99 =
13、95.04%, a loss of 100%-95.04%=4.96%. 【知识模块】 图表 【知识模块】 图表 12 【正确答案】 18 【试题解析】 Germany won a total of 29 medals, while Korea won a total of 11 medals. Therefore, Germany won 18 more medals than Korea. 【知识模块】 图表 13 【正确答案】 5:4 【试题解析】 In total, Italy and France earned 10 bronze and 8 gold medals. Therefore, the ratio of bronze medals to gold medals is 10:8, which simplifies to 5:4. 【知识模块】 图表 14 【正确答案】 44/123 【试 题解析】 The top 5 countries were awarded 123 medals in all, 44 of which were silver medals. Therefore, the percentage of silver medals is 44/123, or approximately 36%. 【知识模块】 图表
