Question 31

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 🗳️ To make the comparison, set up two proportions. Quantity A is x in the equation and Quantity B is y in the equation You can easily see that x= 2.5 and that y= 2.5.

  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 32

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 🗳️ Wheel Bs radius, and therefore its circumference as well, is 50 times greater than Wheel As (3:150 = 1:50). In order to travel as far each minute as Wheel A travels per hour, Wheel Bs circumference would need to be 60 times greater (since there are 60 minutes per hour), but its not that big. Thus, Wheel A travels further in one minute than Wheel B does in one hour. (The number of revolutions per minute is not relevant, since the rotation rate is the same for both wheels.)

  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 33

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 🗳️ All terms on both sides cancel out:

  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 34

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 🗳️ The price of the coat described in Column A = $300 - (.07 x $300) = $300 - $21 = $279. The price of the coat described in Column B = $200 + (.4 - $200) = $200 + $80 = $280.

  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 35

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 🗳️ Any non-zero number raised to the power of zero is 1, and so

  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.
