Question 41

A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: C 🗳️ In either series of integers, the terms are distributed symmetrically to the left and right of zero (0) on the number line. Hence, in both cases the sum of the integers is zero (0).

  1. The quantity in Column A is greater;
  2. The quantity in Column B is greater;
  3. The quantities are equal;
  4. The relationship cannot be determined from the information given.

Question 42

A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: A 🗳️ The leg from home to work is slower than the return leg, and therefore the average speed going to work (Quantity B) is slower than the combined average (Quantity A).

  1. The quantity in Column A is greater;
  2. The quantity in Column B is greater;
  3. The quantities are equal;
  4. The relationship cannot be determined from the information given.

Question 43

A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: B 🗳️ First, Quantity A: The greatest common factor of 20,45, and 90 is 5. As for Quantity B,the sum of the three numbers given is clearly greater than 5. Thats all you need to know to conclude that Quantity B is greater than Quantity A and that the correct answer is choice (B).

  1. The quantity in Column A is greater;
  2. The quantity in Column B is greater;
  3. The quantities are equal;
  4. The relationship cannot be determined from the information given.

Question 44

A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: D 🗳️ Quantity A = Quantity B = .078x. The comparison, then, is between and .078x. If x happens to equal then both quantities would equal 1. Otherwise, the two quantities are unequal; in fact, theyre reciprocals. (Their product is 1.) For example, if x= 1, then Quantity A is a fraction greater than 1 by an order of more than 10, while Quantity B is a fraction less than 1 by the same order. That is all you need to know to conclude that choice D. is correct.

  1. The quantity in Column A is greater;
  2. The quantity in Column B is greater;
  3. The quantities are equal;
  4. The relationship cannot be determined from the information given.

Question 45

A. The quantity in Column A is greater; B. The quantity in Column B is greater; C. The quantities are equal; D. The relationship cannot be determined from the information given. Reveal Solution Hide Solution Discussion 241 Suggested Answer: D 🗳️ If P 0, then Quantity A < Quantity B . On the other hand, if P+Q < 0, then Quantity A = Quantity B.

  1. The quantity in Column A is greater;
  2. The quantity in Column B is greater;
  3. The quantities are equal;
  4. The relationship cannot be determined from the information given.
