Aptitude Test Topic: Quantitative Comparison

Questions of this type ask you to compare two quantities — Quantity A and Quantity B — and then determine which of the quantity is greater.

Directions

Each question has two quantities to be compared: one in a box in the left hand column and one in a box in the right hand column. Compare the quantities taking into consideration any other information given and choose:

if the quantity on the left is greater
if the quantity on the Right is greater
if both are equal
if the relationship cannot be determined without further information.

Question Statement:

Column A	Column B
The average (arithmetic mean) high temperature for x days is 70 degrees. The addition of one day with a high temperature of 75 degrees increases the average to 71 degrees.
x	5

Quantity A is greater.

Quantity B is greater.

The two quantities are equal.

The relationship cannot be determined from the information given.

Explanation:

Correct Answer: B

If the average high temperature for x days is 70 degrees, then the sum of those x high temperatures is 70x. The sum of the high temperatures, including the additional day that has a temperature of 75 degrees is, therefore, 70x + 75. Next, use the average formula to find the value of x:

In this formula, 71 is the average, 70x + 75 is the total, and there are x + 1 days. Substituting this information into the formula gives:

gre plugging in average formula -99256400

To solve, cross-multiply to get 71x + 71 = 70x + 75. Next, simplify to find that x = 4. Therefore, Quantity B is greater. The correct answer is (B).
