CAT 2026 Quantitative Aptitude Chapter-Wise Weightage: Top Topics

Arithmetic is the highest-weighted chapter in CAT 2026 Quantitative Aptitude, contributing 8–10 questions out of 22 — mastering it alone can secure nearly 45% of your QA score.

The Quantitative Aptitude (QA) section in CAT 2026 has 22 questions across five major topic areas to be solved in 40 minutes. Based on analysis of CAT 2022, 2023, and 2024 papers, certain chapters appear consistently with higher frequency. Knowing this distribution helps you allocate study time where it matters most.

• Total QA questions in CAT 2026: 22 (mix of MCQ and TITA)
• Time allotted for QA section: 40 minutes
• Arithmetic accounts for 36–45% of all QA questions in recent CAT exams
• Algebra and Number System together contribute 30–35% of the section
• TITA questions (no negative marking) typically make up 6–8 questions in QA

High-Priority Chapters for CAT 2026

Three chapters consistently dominate CAT QA. Your preparation should centre on these before moving to lower-weightage topics.

Arithmetic — Highest Weightage (36–45%)

Arithmetic is the most rewarding chapter in CAT QA, delivering 8–10 questions in every recent paper. Key sub-topics and typical question counts:

• Time, Speed and Distance — trains, boats, relative motion (typically 2–3 questions)
• Percentages and Profit and Loss — foundational and high-frequency (1–2 questions)
• Time and Work — includes pipes and cisterns variants (1–2 questions)
• Ratio, Proportion and Mixtures — alligation method problems appear regularly (1–2 questions)
• Simple and Compound Interest — straightforward formula application (1 question)

Algebra — Second Highest Weightage (22–27%)

Algebra contributes 5–6 questions and spans several interconnected sub-topics:

• Linear and Quadratic Equations — direct and word-problem formats (1–2 questions)
• Functions and Graphs — growing presence since CAT 2021 (1–2 questions)
• Logarithms and Surds — often tested alongside functions (1 question)
• Sequences and Series — AP, GP and special series (1 question)
• Inequalities — modulus and quadratic forms (1 question)

Geometry and Mensuration (13–18%)

Geometry questions carry strong marks but are time-intensive. Triangles and circles appear in almost every CAT paper, typically 1–2 questions each. 3D mensuration (cones, spheres, cylinders) also appears. If time is limited, focus on triangles and circles for the best return per hour studied.

Number System (9–13%)

Remainder theorem, LCM-HCF, and factorial problems appear in almost every CAT paper. This chapter rewards pattern recognition and shortcut application over formula memorisation. Aim for 2–3 correct attempts here.

Modern Mathematics (4–9%)

Permutations, Combinations, and Probability typically contribute just 1–2 questions and are among the hardest in the section. Prepare this chapter last if you are time-constrained.

How to Use This Weightage Data for CAT 2026 Preparation

Use the weightage distribution to build a priority-based study schedule. Here is a recommended 12-week approach:

1. Weeks 1–4 — Arithmetic first: Dedicate the most hours here. Cover all sub-topics and build speed through daily timed practice sets. This chapter alone can yield 8–10 correct attempts.
2. Weeks 5–7 — Algebra: Study equations, functions, logarithms, and sequences together — they share conceptual links. Focus on CAT-style word problems over textbook drills.
3. Weeks 8–9 — Geometry: Prioritise triangles and circles. Skip advanced 3D mensuration if overall preparation time is limited.
4. Weeks 10–11 — Number System: Practise remainder theorem, LCM-HCF, and cyclicity shortcuts. Build speed through pattern-based problem sets.
5. Week 12 — Modern Mathematics and full mocks: Cover P&C and Probability lightly. Use this week for full-length mock CATs and targeted weak-area revision.

TITA strategy: Since 6–8 QA questions carry no negative marking, attempt every TITA question even when unsure. This is your lowest-risk scoring opportunity in the QA section.
