Difficulty: Medium

Category: Problem Solving and Data Analysis / Rates, Ratios, Proportions, and Percentages

Strategic Advice: When lots of information is presented in a graphic, make sure you look at the answer choices before you start calculating. Chances are that you'll only need to use a small part of the data.

Getting to the Answer: Manipulate the three-part percent formula, Percent × whole = part, to read Percent = part ÷ whole (or here, Percent = amount invested ÷ sales), and check each year given in the answer choices. To disprove the claim, you're looking for the year or years in which the percent is greater than 60% (greater than 0.6).

, so eliminate A.

. Don't choose (B) yet because 2012 is also in D.

, so eliminate C and D.

This means (B) is correct.
