Permutations and combinations in quantitative aptitude <\/strong>are two closely related topics that you should thoroughly prepare for if you’re getting ready for competitive exams<\/strong><\/a>. Two key mathematical terms that are commonly assessed in quantitative aptitude tests are permutations and combinations. A combination is a selection of items from a given set in any order, whereas a permutation is an arrangement of objects from a given set in a defined order. It can be challenging to distinguish between the two, but it can be made simpler by knowing some quick tricks for permutation and combination issues. This topic has been covered in great length in this article. Let’s now concentrate on practice questions about combinations and permutations.<\/p>\n\n\n\n\n\n\n

What are Aptitude Questions on Permutation and Combination?<\/h2>\n\n\n\n

The methods of choosing certain items from a collection of objects to create subsets, either with or without replacement, are permutation and combination. It outlines the different configurations for a given set of data. Permutations are when we choose items or data from a particular group; combinations are when we express them in a particular order. These terms are important for understanding mathematics. Let\u2019s try to understand these important terms using some examples:<\/p>\n\n\n\n

Concept<\/strong> <\/td>Definition<\/strong><\/td>Example<\/strong><\/td><\/tr>
Permutations<\/strong> <\/td>Permutation is a process of selecting
different items where the
order of selection matters.<\/td>		Arranging people, numbers, alphabets, digits, vegetables, or colors.<\/td><\/tr>
Combinations<\/strong><\/td> Combination is a technique for determining the number of different possible arrangements where the order of selection is not relevant.<\/td>Selecting food menu, clothes, subjects for courses, etc.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Aptitude Questions on Permutation and Combination involve a lot of formulas. The most important formulas are:<\/p>\n\n\n\n

Formula for Permutations<\/strong><\/td>Formula for Combinations<\/strong><\/td><\/tr>
nPr = n! \/ (n\u2212r)!<\/td>nCr = n! \/ (r! * (n\u2212r)!)<\/td><\/tr>
Example: nPr for selecting k things from n objects:<\/td>Example: nCr for selecting k things from n objects without repetition:<\/td><\/tr>
nPr = n! \/ (n\u2212k)!<\/td>nCr = n! \/ (k! * (n\u2212k)!)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Relation between Permutation and Combination<\/h2>\n\n\n\n

Permutation and Combination both refer to selecting objects from a set but with different importance on the order of selection. Mathematically, permutation counts arrangements, while combination counts selections. A mathematical relationship between permutation and combination is given by:<\/p>\n\n\n\n

nPr = nCr \/ r!<\/strong><\/td><\/tr>
nCr = r! x nPr<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Difference between Permutation and Combination<\/h2>\n\n\n\n
