GRE-Style: Data Interpretation Set

GRE Quantitative · Axiom Academy

EXAMPLE GRE-Style: Data Interpretation Set Reading a bar chart, finding the total, and computing one category's share. The bar chart below shows how much a school's weekend bake sale earned from each item, in dollars. What percent of the bake sale's total revenue came from cupcakes ? Round to the nearest tenth of a percent. Chart: Bake Sale Revenue by Item (dollars) Nice work — you just worked a complete GRE data interpretation question the way it actually shows up on the test. Read every bar first: a "percent of total" question needs the WHOLE data set, not just the one bar being asked about. Fraction before percent: set up , simplify it, and only then multiply by — simplifying first keeps the arithmetic small. Result: cupcakes made up of the bake sale's revenue. Every GRE data-interpretation question reduces to this same two-step move: pull the right numbers off the figure, then apply ordinary fraction/percent arithmetic.
