CAT: 8 Tips to Learn Permutation and Combination Concepts


CAT Exam: The Indian Institutes of Management is scheduled to conduct the CAT 2023 on November 26, 2023. The exam will be held in three sessions for Verbal Ability and Reading Comprehension, Data Interpretation and Logical Reasoning and Quantitative Ability. Candidates who are going to appear for the Common Admission Test 2023 must be preparing day and night for the computer-based test for admission to graduate management programs.
In the CAT exam, the concepts of permutations and combinations play a significant role in assessing a candidate’s problem-solving abilities and logical reasoning skills. CAT, being one of the most competitive management entrance exams in India, often presents intricate questions related to permutations and combinations. These questions are designed to evaluate a candidate’s aptitude for handling complex situations, making decisions, and analysing patterns.
Candidates are required to apply the fundamental principles of permutations and combinations to solve problems involving arrangements, selections, and probability. Mastery over these concepts is essential as it empowers candidates to approach a wide array of questions in different formats. Permutations and combinations are important concepts in mathematics and are frequently tested in exams like the Common Admission Test.
Here are 8 tips to help you understand and master permutations and combinations for CAT;
Understand the Basics
Make sure you have a strong understanding of fundamental concepts. Permutations deal with arrangements, and combinations deal with selections. Understanding the difference between the two is crucial.
Formulas and Notations
Familiarise yourself with the basic formulas of Permutation and Combination.
Permutation: A permutation is an arrangement of r objects from a set of n objects. The order in which the objects are arranged matters.
Combination: A combination is a selection of r objects from a set of n objects. The order in which the objects are selected does not matter.
Practice Regularly
Practice a wide variety of problems regularly. CAT-level questions can be complex, so it’s important to be comfortable with different types of problems and patterns.
Visualise Problems
Use visual aids and diagrams to understand problems better, especially those involving arrangements. Visualization can help in solving complex problems more effectively.
Solve Previous Years’ Papers
Work through previous years’ CAT papers and mock tests. This will help you understand the pattern of questions asked in the exam and familiarize yourself with the level of difficulty.
Focus on Conceptual Understanding
Instead of memorizing formulas, focus on understanding the logic and reasoning behind permutations and combinations. This understanding will enable you to solve a wider range of problems.
Master Application Problems
Practice problems related to real-life situations where permutations and combinations are applicable. This can include problems related to seating arrangements, distribution, and committee formations.
Time Management
Time management is crucial in CAT. Practice solving problems within a time limit to improve your speed and accuracy. This will also help you gauge which types of questions take more time and where you need to improve.
Disclaimer: Please note that these are some common tips, candidates are advised to refer to the official CAT syllabus and sample question papers available on the CAT website to get a more precise understanding of what to expect in the Permutation and Combination section for a specific year.
