Answer:
120 ways
Explanation:
We have total 5 books which needs to arranged in the shelf.
We know that "n different things can be arranged in n! ways".
Since, here number of books is 5. Hence, n = 5
Thus, we can conclude that 5 diffident books can be arranged in 5! ways.
Let us find the value of 5!.
5!
= 5 ×4 ×3 ×2 ×1
= 120
Thus, 5 different books can be arranged in a shelf in 120 ways.
