CAT 2026 QA Topics: A 6-Year Question Pattern Analysis

We tagged and analysed all 330 Quant questions across 15 official CAT papers from 2021 to 2025 — every topic, sub-topic, and recurring scenario-type. Here’s what that dataset actually shows about CAT 2026 QA topics, and just as importantly, what it doesn’t.

How This Analysis Was Built

Before drawing any conclusions about CAT 2026 QA topics, the underlying data was checked for integrity. All 15 official Quant papers from 2021–2025 were retrieved successfully, with every paper confirmed to contain exactly 22 QA questions — 330 questions in total, matching the tagged dataset exactly. Each question was classified by topic and scenario type directly from its wording, without solving it for an answer, to keep the classification purely structural.

• Difficulty statistics (Correct% / Incorrect%) are only publicly available for 2021, 2024, and 2025 — any difficulty-related claim is restricted to those 9 of 15 slots, not the full dataset.
• Two question pairs across different official slots were found to be word-for-word identical — flagged as anchor-item reuse, not a taught content pattern.
• No claim in this analysis extends to the 2026 paper or any future administration. Every statement here is traceable strictly to this 2021–2025, 330-question dataset.

The Big Picture: Where the Questions Actually Come From

The topic-wise split across all five years is remarkably stable.

Arithmetic: The Paper’s Heaviest Engine

Of every broad category among CAT 2026 QA topics, Arithmetic deserves the most attention by sheer weight. At 138 of 330 questions, it isn’t just the largest topic — it’s tested differently from the others. A full 61% of Arithmetic questions are multi-concept, chained scenarios, the strongest single signal in the entire dataset. CAT almost never asks a standalone “find the profit%” or “find the average” question; it layers a condition on top nearly every time.

Algebra: Condition-Layered, Not “Solve for x”

Algebra is the most evenly spread topic in the dataset — no single question-framing dominates the way multi-concept scenarios dominate Arithmetic. Logic and condition-based reasoning leads at 32%, but optimization, formula-based, and property-driven questions all contribute meaningfully.

Geometry and Number System

Geometry (45 questions, 13.6%) is the dataset’s most “textbook” section — 76% of its questions are property or formula-driven, the least likely topic to blend with another chapter. It’s also the least volatile topic year to year, holding steady in an 8–10 question band across all five years.

Number System (57 questions, 17.3%) runs the opposite way — 53% logic or condition-based, rarely a plug-in formula question. Exponents and Logarithms alone account for 24 of 57 questions (42%) and are the single most reliable Number System presence in the dataset, never the smallest sub-topic and never absent in any year.

Modern Math: Small but Sharply Focused

Among CAT 2026 QA topics, Modern Math is the one most aspirants underweight — and with reason, since at just 12 of 330 questions (3.6%), it’s the smallest topic. But it has the most concentrated framing profile in the entire dataset: 67% pure logic or constraint reasoning, and 0% property-based or multi-concept questions.

• Combinatorics (P&C): 10 questions, present in 5/5 years — never a bare nCr/nPr calculation; always wrapped in a distribution-with-constraint or path-counting scenario.
• Set Theory: just 2 questions, appearing only in 2022 and 2025 — insufficient evidence to call this a yearly fixture; treat it as intermittent rather than guaranteed.

Ten Recurring Scenario-Archetypes in CAT 2026 QA Topics

Grouping questions by underlying scenario rather than textbook chapter surfaces ten templates that CAT keeps reusing — the same puzzle logic, dressed in different numbers and framing.

• Successive Replacement / Dilution Mixture — ~9 instances, 5/5 years
• Functional Equations as Arithmetic Wrapper — 6 instances, 5/5 years
• Absolute-Value Condition Puzzles — 9 instances, 5/5 years
• Successive % Change Chains — 6 instances, 4/5 years
• CI/SI Reinvestment Equivalence — 7 instances (including one verified word-for-word repeat), 5/5 years
• Cevian / Mass-Point Triangle Ratios — 5 instances, 5/5 years
• Pairwise Combined Time & Work — ~7 instances, 5/5 years
• Set-Overlap / % Participation Min-Max — 4 instances, 4/5 years
• Digit-Constraint Number Construction — 7 instances, 4/5 years
• Range of a Rational Function — 2 instances, 2/5 years

The takeaway from this list isn’t the exact counts — it’s that CAT reuses puzzle logic far more than it invents new mathematics. Recognising the archetype often matters more than recalling the formula.

What’s Guaranteed vs. What’s Just a Trend

Not every pattern in this dataset carries equal weight. Some sub-topics recur every single year; others cluster in specific years and shouldn’t be treated as fixtures.

How CAT Actually Tests Each Topic

Beyond which topics appear, how they’re tested varies sharply by section — formula recall turns out to be the exception, not the rule.

What This Means for CAT 2026 QA Topics Prep

Don’t prepare chapters — prepare engines. Within every recurring sub-topic, CAT overwhelmingly favours a small set of scenario-templates, reused with new numbers and framing rather than new mathematics. That has direct implications for how to prioritize CAT 2026 QA topics:

• Weight your practice time toward Arithmetic’s chained, multi-concept scenarios rather than isolated single-formula drills.
• Treat Algebra’s Quadratics and Progressions as condition-layered problems by default, not plain textbook solves.
• Build genuine theorem fluency in Geometry — it’s the one section where knowing the right property most directly unlocks the answer.
• Don’t skip Exponents/Logarithms in Number System — it’s the single most reliably present sub-topic outside Arithmetic.
• Practice P&C as scenario-wrapped counting, not bare formula application, and treat Set Theory as a bonus rather than a certainty.
