# Number of permutations that can be made using all the letters of the word MATRIX is

- 120
- 240
- 480
- 720

Hint:

### Basically Permutation is an arrangement of objects in a particular way or order. While dealing with permutation one should concern about the selection as well as arrangement.

In Short, ordering is very much essential in permutations. In other words, the permutation is considered as an ordered combination.

## The correct answer is: 720

### The word MATRIX is a 6 letter word

Thus, number of permutations that can be made using all the letters of the word MATRIX is 6! = 720
