Arithmetic constitutes 60-70% of the CAT Quantitative Ability section, making it the highest-yield topic. This cheat sheet provides essential shortcuts—such as $100$ base method for Percentages, Alligation for Averages, and Ratio-proportionality for Work—to solve complex problems in under 60 seconds, ensuring you maximize your score efficiently.
What is the Exam?
The Common Admission Test (CAT) is the gateway to the premier Indian Institutes of Management (IIMs) and numerous other top-tier business schools in India. Conducted annually, it is a computer-based management aptitude test that evaluates a candidate's ability in Quantitative Ability (QA), Data Interpretation & Logical Reasoning (DILR), and Verbal Ability & Reading Comprehension (VARC). For management aspirants, cracking CAT is the definitive step toward professional growth, leadership, and high-tier corporate placement.

Eligibility Criteria
According to the official eligibility guidelines published by the IIM CAT official portal, candidates must hold a Bachelor’s degree from a recognized university with at least 50% marks or equivalent CGPA (45% for SC, ST, and PwD categories). Final-year graduation students are also eligible to apply. We at Exam Bhai strongly advise all candidates to verify their specific university grading conversion factor before filling out the application.
Application Process
The application process is conducted entirely online. Candidates must visit the official IIM CAT website, complete the registration, upload necessary documents (photograph, signature, and category certificates), and pay the requisite application fee. Ensure your details match your government-issued ID cards exactly.
Preparation Strategy
To master Arithmetic, consistency is key. We at Exam Bhai recommend the following:
- Conceptual Clarity: Do not jump to shortcuts before understanding the basic derivations. Use subject-specific study materials for Management on Exam Bhai to build your base.
- The Shortcut Vault: Create a dedicated notebook for your arithmetic formulas. For instance, instead of standard division, learn to convert percentages to fractions (e.g., $16.66% = 1/6$) to solve calculations mentally.
- Mock Strategy: Use advanced analytical mock reports for Management on Exam Bhai to identify which arithmetic topics are draining your time.
- TITA Practice: Since TITA questions have no negative marking, these are your best opportunity to boost your raw score. Prioritize accuracy over blind guessing.
Cut-Off Trends
Cut-offs are determined by the individual IIMs based on the difficulty level of the paper and the number of test-takers. Per data from the IIM CAT official website, top-tier IIMs (like IIM Ahmedabad, Bangalore, and Calcutta) typically require a percentile of 99+ for General category candidates. Remember, these are institutional benchmarks and can fluctuate significantly based on annual performance trends. Always aim for a buffer of 3-5 percentile points above the historical cut-offs.
Frequently Asked Questions
Q1: How many questions in CAT are from Arithmetic? A1: Arithmetic typically contributes about 8-10 questions out of 22 in the Quantitative Ability section.
Q2: Is it possible to clear CAT without mastering Arithmetic? A2: While technically possible by focusing on Algebra/Geometry, it is highly risky. Arithmetic is the fastest section to solve, giving you more time for complex topics.
Q3: What is the best way to memorize the cheat sheet? A3: Don't rote learn. Practice 20 problems per formula until the shortcut becomes intuitive.
Q4: Should I use calculators during prep? A4: Use the on-screen calculator only during full-length mocks. For daily practice, rely on mental math to increase speed.
Q5: Are TITA questions harder than MCQs? A5: Not necessarily. TITA questions often test direct application of concepts. The lack of negative marking makes them highly scoring.
Q6: Does the syllabus change every year? A6: The core syllabus remains consistent, though the distribution of questions across topics may vary based on the convener IIM's strategy.
