Watch 25 easy GMAT Official Guide 2026–2027 Quant questions explained
The video below explains 25 easy questions from the GMAT Official Guide 2026–2027 Quantitative Review. Each official-style GMAT question is solved out loud: read the prompt, set it up, do the arithmetic without a calculator, and confirm the answer. The goal is not to memorize answers — it is to internalize a repeatable setup for arithmetic, fractions, percentages, ratios, algebra, and word problems so the easy and medium bands become automatic and you save your time for the questions that decide your Quant score.
How to study with this video lesson
Passive watching does not move a Quant score. Treat the lesson as an active study session and you will get far more out of it:
- Attempt first, then watch. Pause before each worked solution and try the question on paper. Give yourself roughly two minutes, the same pace the real GMAT Focus expects.
- Write your setup, not just an answer. Jot the equation, the ratio, or the percentage relationship you used. Most missed points come from a rushed setup, not bad arithmetic.
- Pause and compare. When you reach a question you got wrong, stop and find the exact step where your path diverged from the clean one.
- Mark, do not erase. Keep your wrong work visible so you can see the pattern in your mistakes later.
What these 25 GMAT Official Guide 2026–2027 questions cover
The 25 easy questions in this lesson are a tour of the foundations of GMAT Focus Quantitative Reasoning. Here is the terrain you will practice and why each piece matters on test day:
- Arithmetic and number properties — factors, multiples, odd/even, and the rules that turn a slow computation into a one-line answer.
- Fractions and estimation — converting cleanly between fractions, decimals, and percents, and using estimation to eliminate answer choices fast.
- Percentages — percent change, percent of a percent, and the difference between "increased by" and "increased to," a classic trap.
- Ratios and proportions — scaling parts to a whole, combining ratios, and converting between ratio and fraction form quickly.
- Basic algebra — solving linear equations, substitution, and translating words into expressions without losing a sign.
- Word problems — rate, work, mixture, and simple profit setups where the hard part is the reading, not the math.
Notice that none of this requires a calculator, and the GMAT Focus Quant section does not give you one. That is the whole reason to drill the foundations: it trains mental arithmetic, estimation, and a disciplined setup so you stay fast and accurate under the clock.
Why the foundations deserve your attention
Strong test-takers often rush the foundational questions and lose points to careless errors. On an adaptive exam like the GMAT Focus, a missed easy or medium question costs you more than a missed hard one, because the algorithm reads it as a sign you have not mastered the fundamentals. Building a near-perfect hit rate on arithmetic, fractions, percentages, ratios, and algebra is the cheapest, fastest score gain available. This lesson is exactly that practice.
Turn your mistakes into a score with an error log
The single highest-leverage habit in GMAT prep is the error log. After each study session with the video, do not just note which questions you missed. For every miss, record four things:
- The question type (e.g. percent change, ratio, linear equation).
- The exact error (misread the question, wrong formula, arithmetic slip, ran out of time).
- The fix — the one sentence that would have kept you on the right path.
- A re-test date — come back in a week and redo the same question cold.
After a few sessions, your log reveals the two or three patterns that account for most of your lost points. That is where targeted practice pays off, and it is exactly how MBA House tutors turn diagnostic data into a focused study plan.

The video explains 25 easy questions from the GMAT Official Guide 2026–2027 Quantitative Review. Each official-style GMAT question is solved step by step, so you see the clean, calculator-free setup behind every answer across arithmetic, fractions, percentages, ratios, algebra, and word problems.
What is the GMAT Official Guide Quantitative Review 2026–2027?
It is the official supplementary Quant practice book for the GMAT Focus Edition. It contains retired, official-style Quantitative Reasoning problems organized by topic and difficulty, so you practice with the same arithmetic, algebra, and word problems you will see on test day.
How should I study with this video lesson?
Watch actively, not passively. Pause before each worked solution, attempt the setup yourself under a soft two-minute timer, then play the explanation to compare your reasoning. Keep an error log of every miss so you review the pattern, not just the answer.
What GMAT Focus Quant topics does the lesson cover?
It works through the foundations of GMAT Focus Quantitative Reasoning: arithmetic and number properties, fractions, percentages, ratios and proportions, basic algebra, estimation, and word problems such as rate, work, and mixture.
Does the GMAT Focus Quant section allow a calculator?
No. The GMAT Focus Quantitative Reasoning section does not allow a calculator, which is why the lesson trains the mental arithmetic, estimation, and clean setup you need to stay fast and accurate without one.
How much time should I spend per Quant question?
On the GMAT Focus you have roughly two minutes per Quantitative Reasoning question. Practice at that pace so timing becomes automatic, then use your error log to find the question types that consistently slow you down and drill those specifically.
