Practice for GRE Multiple-Choice Questionsįor question 3, select one answer from the list of five answer choices.ģ. Because Quantity A is not always greater, choice (A) can now be eliminated. In this case, however, the quantities are equal. Again, these numbers satisfy the equation provided in the problem. When choosing a second set of numbers, try something less common such as making a = b = 1. ![]() Because Quantity B is not always greater nor are the two quantities always equal, choices (B) and (C) can be eliminated. These numbers satisfy the equation as 8 2 = 4 3 = 64. Try different integers for a and b that satisfy the equation a 2 = b 3 such as a = 8 and b = 3. See the AnswerĪnswer: (D) The relationship cannot be determined from the information given. To solve, cross-multiply to get 71x + 71 = 70x + 75. Substituting this information into the formula gives: In this formula, 71 is the average, 70x + 75 is the total, and there are x + 1 days. Next, use the average formula to find the value of x: The sum of the high temperatures, including the additional day that has a temperature of 75 degrees is, therefore, 70x + 75. If the average high temperature for x days is 70 degrees, then the sum of those x high temperatures is 70x. (D) The relationship cannot be determined from the information given. The addition of one day with a high temperature of 75 degrees increases the average to 71 degrees. The average (arithmetic mean) high temperature for x days is 70 degrees. ![]() The relationship cannot be determined from the information given.ġ.Your job is to compare the two quantities and decide which of the following describes the relationship: Quantitative comparison questions ask you to compare Quantity A to Quantity B. ![]() Practice for GRE Quantitative Comparison Questions Don't use anything fancier when you tackle this GRE math practice!
