Arithmetic Reasoning

 

As an ASVAB tutor, I present the topic of percentages as one of the important topics that I review in my classes on Arithmetic Reasoning.  There are many different types of percentage questions that could appear on the ASVAB.  I review a number of different types of percentage questions in my ASVAB prep course.

Yesterday I presented an Arithmetic Reasoning question on percentage.

The question is:

A piece of luggage is marked 1/8 off its original price.  What percentage is being taken off the original price?

  1. 5%
  2. 18%
  3. 22%
  4. 5%

In order to solve this problem, it is necessary to change a fraction to a percent.

To change a fraction to a percent, set up a proportion.

1/8 = x/100

Cross multiply and solve for x

8x = 100

Divide by 8 to get the answer.

x = 12.5%

The answer is Choice A. 12.5%
