These lessons are part of a series of practice test questions for the quantitative reasoning section of the GRE revised General Test.

These are the directions for the Quantitative Comparison Questions.

Directions: Compare Quantity A and Quantity B, using additional information centered above the two quantities if such information is given, and select one of the following four answer choices:

(A) Quantity A is greater.

(B) Quantity B is greater.

(C) The two quantities are equal.

(D) The relationship cannot be determined from the information given.

Example 1:

Quantity A: Average (arithmetic mean) of integers from -50 to -1 inclusive

Quantity B: Average (arithmetic mean) of integers from -50 to 0 inclusive Example 2:

w + x = -4

x + y = 25

y + w = 15

Quantity A: Average (arithmetic mean) of w, x and y

Quantity B: 6 Example 3:

Quantity A: The average (arithmetic mean) of 3^{2}, 3^{4} and 3^{6}

Quantity B: 3^{4}
Example 4:

a, b, c and d are different positive numbers. The average (arithmetic mean) of a and b is 30. The average of a, b, c and d is 40.

Quantity A: The greatest possible value of d.

Quantity B: 99

Example 5:

Triangle A has sides with length 5, 5 and 8.

Triangle B has sides with length 8, 8 and 5.

Quantity A: The average (arithmetic mean) measure of 3 angles of triangle A

Quantity B: The average (arithmetic mean) measure of 3 angles of triangle B.
