Arithmetic is one of the most important and high-weightage areas in the CAT exam, forming the backbone of the Quantitative Ability section. It focuses on practical, real-life mathematical concepts that test a candidate’s ability to analyze numerical situations and solve problems logically and efficiently. Key topics in CAT Arithmetic include percentages, ratios and proportions, profit and loss, averages, mixtures and alligations, time and work, time–speed–distance, simple and compound interest, and pipes and cisterns. These concepts frequently appear in the exam in the form of word problems that require strong conceptual clarity and quick calculations. A typical CAT Arithmetic question might involve comparing ratios, calculating profits after multiple percentage changes, or determining work rates when multiple entities are involved. Many problems are designed to test your ability to interpret information, translate real-world scenarios into mathematical equations, and solve them under time pressure. Mastering Arithmetic not only improves accuracy but also builds the numerical intuition required to tackle complex CAT Quant problems effectively.
