Data Interpretation Sets (Multi-Question)

GRE Quantitative · Axiom Academy

LESSON Data Interpretation Sets (Multi-Question) One chart, one table, up to three questions — the figure never changes, only what you're asked to find in it. Here is the shared figure for this lesson: a company's revenue by product line, in thousands of dollars , from 2020 to 2023. Every question below reads numbers from this exact table — nothing about the data changes between questions, only which cells you look at and what you do with them. Notice the units: "210" means 210,000 , not 210 — the single most common trap on these sets is missing that revenue is reported in thousands . 2. Question 1 — Direct Read: Percent Change Question: By what percent did Gadgets revenue increase from 2020 to 2023? Solution: old value (2020) is 80 thousand, new value (2023) is 200 thousand. "Tripled" means +200% and "doubled" means +100%. Gadgets went from 80 to 200 — that's 2.5× the original, so +150%. No calculator needed: recognizing the multiple is faster than long division. 3. Question 2 — Ratio Within the Figure Question: In 2022, Widgets revenue was what fraction of total revenue? Solution: Widgets in 2022 is 180; the 2022 total is 380. 4. Question 3 — Synthesis: Comparing Trends Question: Which product line had the largest average year-over-year dollar increase from 2020 to 2023? For "average year-over-year," you don't need every yearly step — just . Largest absolute increase: 40,000 per year on average.
