The remaining choices are possible values of x. The only number in the answer choices that is not a factor of 216 is 5. Plug the information given into the formula for the area of a triangle to learn more about the relationship between x and y: The product of x and y is 216, so x needs to be a factor of 216. If both x and y are integers, which of the following could be the value of x ? If there were 100 dogs sold in March, then 50 cats were sold in April, 200 dogs were sold along with 150 cats. The total number of dogs and cats sold during those two months is 600, which is too large, so eliminate (C), (D), and (E). In April, 240 dogs were sold, along with 180 cats. If 120 dogs were sold in March, then 60 cats were sold that month. Plug In the Answers, starting with the middle choice. If the total number of pets the store sold in March and April combined was 500, how many dogs did the store sell in March? In April, the store sold twice the number of dogs that it sold in March, and three times the number of cats that it sold in March.

In March, the store sold twice as many dogs as cats. A certain pet store sells only dogs and cats. 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.
