- $58$
- $48$
- $38$
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$9600=2^{7}\times3\times5^{2}$
Number of divisors $=\left(7+1\right)\left(1+1\right)\left(2+1\right)$
$=\left(8\right)\left(2\right)\left(3\right)$
$=48$

Notes on Permutations
Concepts Used:
Permutations
A permutation is an arrangement of multiple objects in a particular order taken a few or all at a time. The formula for permutation is as follows:
\(^nP_r = \frac{n!}{(n-r)!}\)
nPr = permutation
n = total number of objects
r = number of objects selected
Types of Permutation
- Permutation of n different things where repeating is not allowed
- Permutation of n different things where repeating is allowed
- Permutation of similar kinds or duplicate objects
