28%. After a 20% cut the price is 0.8 of the original; a further 10% off gives 0.8 × 0.9 = 0.72 (72% of the original), so the total discount is 28%. Successive percentages multiply — they do not simply add to 30%.
GMAT Quantitative Reasoning — Topics & Strategy
GMAT Quantitative Reasoning has 21 problem-solving questions in 45 minutes. The Focus Edition streamlined it: it focuses on arithmetic and algebra, drops geometry, and moved Data Sufficiency into the Data Insights section. No calculator is allowed.
The section rewards mental-math fluency and clean reasoning under time pressure — not advanced maths.
What Quant covers
- Arithmetic — numbers, fractions, ratios, percentages, powers and roots.
- Algebra — equations, inequalities, functions and word problems.
- Problem-solving reasoning — translating a word problem into maths quickly.
- No geometry, and no on-screen calculator (unlike the GRE).
Strategy that works
- Build mental-math fluency so you rarely need to write out routine steps.
- Translate word problems into equations immediately, then solve.
- Estimate to eliminate impossible answer choices before doing full calculations.
- Answer every question — an unanswered question hurts more than a wrong guess.
- Use the bookmark feature to flag hard questions and return with your remaining time.
Rebuild GMAT Quant intuition with simulations
GMAT Focus Quant is algebra and arithmetic under time pressure. These simulations make the underlying patterns visible, so you spend exam time solving rather than recalling.
- Linear equations: graphs, slope and simultaneous pairs
- Quadratic functions and their graphs
- Arithmetic and Geometric Sequences
- Mean, Median and Mode
- Probability: experimental vs theoretical probability
- Sets and Venn Diagrams
- Coordinate Geometry: Distance, Midpoint, Slope, Section Formula and Locus
- Function Transformations: Shifts, Stretches and Reflections
- All science and math animations

Frequently asked questions
No — the Quantitative Reasoning section does not allow a calculator, so mental-math fluency is essential. (An on-screen calculator is available only in Data Insights.)
No. The Focus Edition removed geometry from Quant; it focuses on arithmetic and algebra problem-solving.
Data Sufficiency moved to the Data Insights section in the Focus Edition, so you will meet it there rather than in Quant.
