Strategies for Quantitative Comparisons
- memorize the directions now to save time during the test
- try and avoid calculating the answers, just compare the two figures given
- when the quantities in each column are fixed numbers, avoid answer ‘D’ “The relationship cannot be determined from the information given.”
- Use your scratch paper to make rough sketches or diagrams
Each of the following questions consists of two quantities, one is Column A and one in Column B. You are to compare the two quantities and choose
(A) if the quantity in Column A is greater;
(B) if the quantity in Column B is greater;
(C) if the two quantities are equal
(D) if the relationship cannot be determined from the information given.Question:
Note: The < symbol is used to indicate an angle.
In triangle ABC, m<A is less than m<B, and m<C = 60°
Column A Column B
Side CB Side ABAnswer:A
Explanation: Since the measure of <C is 60, the measure of <A + <B is 120, and therefore the measure of <A is more than ½ of 120, since A is larger than B. Side CB lies opposite the angle with a measure of more than 60 and is therefore larger than side AB, which lies opposite the angle with a measure of 60.
Question:
Column A Column B
2(x + y) 2xyAnswer: D
Explanation: If x = y = 2, then 2(x + y) = 2(2 + 2) = 8 and 2xy = 2(2)(2) = 8. In this case, the columns are equal. For all other choices of x and y, Column B is greater. Hence, the answer cannot be determined by the information given.
