**Download the latest MCQs with answers about Permutation and Combination Problems for Competitive Exam**

Permutation and combination are two important concepts in quantitative aptitude that are frequently tested in competitive exams.

**Permutation**

**Definition:** A permutation is the arrangement of a set of objects in a specific order.
**Formula:** The number of permutations of n distinct objects is defined as n!, or n factorial.
**Application:** Permutations are used to calculate the number of possible arrangements of objects, such as the number of ways to arrange a deck of cards or the number of ways to seat a group of people.

**Combination**

**Definition:** A combination is a selection of a subset of objects from a larger set.
**Formula:** The number of combinations of n distinct objects taken r at a time is defined as nCr, or n choose r.
**Application:** Combinations are used to calculate the number of possible selections of objects, such as the number of ways to choose a team of 3 players from a group of 10 players or the number of ways to choose 5 cards from a deck of 52 cards.

Permutation and combination MCQs are a common type of question that appears in many competitive exams. These questions test your understanding of the concepts of permutation and combination, which are important for quantitative aptitude. Visiting superior exam.pk will enable you to practice permutation and combination MCQs, improve your understanding of these concepts and increase your chances of success in exams.

Here are some tips for solving permutation and combination problems:

**Use the permutation formula:** The permutation formula is used to calculate the number of permutations of a set of objects. The formula is:

where n is the number of objects in the set and r is the number of objects that are being arranged.

**Use the combination formula:** The combination formula is used to calculate the number of combinations of a set of objects. The formula is:

```
nCn = 1
nC1 = n
nC2 = n(n - 1) / 2
```

where n is the number of objects in the set and r is the number of objects that are being selected.

The best way to improve your ability to solve permutation and combination problems is to practice regularly. If you are interested more Permutation and Combination MCQs, you can find them on the superiorexam.pk website.
