If you’re starting the prep, firstly understand the CAT Syllabus Based on our analysis of the Arithmetic CAT Previous Year Questions, this was permutation and combination weightage in CAT: 1 question was asked on this topic (in CAT 2021). CAT Permutation and Combination – Tip 1: A few Permutation and Combination CAT concepts appear in the CAT and other MBA entrance exams every year. Simple Tips and Tricks To Solve CAT Permutation And Combination Questions One can also check out all the other important formulas and tips to solve the permutations and combinations question in the Cracku’s Permutations and Combinations formula sheet PDF. These are some of the basic formulas for permutations and combinations concepts. If its a necklace or bracelet that can be flipped over, the possibilities are ( (n− 1 )!)/ 2 Number of ways of arranging n items around a circle are 1 for n = 1, 2 and (n – 1 )! for n≥ 3. Number of non – negative integral solutions to x 1 +x 2 +x 3 +….+ x n = s where s ≥ 0 is n+s−1 C n−1. Number of positive integral solutions to x 1 +x 2 +x 3 +….+ x n = s where s ≥ 0 is s−1 C n−1. If a items, b items and c items are repeated within n items, they can be arranged in n!/( a! b! c!) ways. If x items out of n items are repeated, then the number of ways of arranging these n items is n! x! ways. The number of ways to partition n distinct things in r distinct slots where arrangement matters = ( (n+r−1)!)/( (r−1)!). The number of ways to partition n distinct things in r distinct slots is given by r n. Number of ways to partition n identical things in r distinct slots so that each slot gets at least 1 is given by n−1 C r−1. The number of ways to partition n identical things in r distinct slots is given. Selecting r objects out of n is the same as selecting (n – r) objects out of n, n C r = n C n – r. Combination: A way of selecting r objects out of n (arrangement does not matter), nCr = n!/((n−r)!*r!). 
Permutation: A way of selecting and arranging r objects out of a set of n objects, nPr = n!/(n−r)!. Arrangement: n items can be arranged in n! ways, N! = N(N-1)(N-2)(N-3)……1. Permutations and Combinations formula sheet PDF 25 permute 3 download#

This article aims to provide you with the 20 most important CAT questions on permutations and combinations that you should solve to master this topic. To successfully solve these questions, test-takers require a thorough understanding of this topic’s concepts. CAT’s Permutation and Combination questions are often challenging and are usually based on different types, such as identical, unidentical, repetition, and without repetition. Instead, the applications of these concepts are being used in other areas, such as probability and number systems. The number of direct questions from Permutation and Combination topics in the Quantitative Aptitude section of the CAT exam appears to be gradually decreasing, as observed by comparing previous question papers.
