यदि (\frac{n!}{(n-5)!}=55440) है तो (n) का मान क्या है?

If (\frac{n!}{(n-5)!}=55440) then what is the value of (n)?

Explanation opens after your attempt
Correct Answer

B. (11)

Step 1

Concept

This is (n(n-1)(n-2)(n-3)(n-4)=55440). Since \(11\times10\times9\times8\times7=55440\), (n=11).

Step 2

Why this answer is correct

The correct answer is B. (11). This is (n(n-1)(n-2)(n-3)(n-4)=55440). Since \(11\times10\times9\times8\times7=55440\), (n=11).

Step 3

Exam Tip

यह (n(n-1)(n-2)(n-3)(n-4)=55440) है। \(11\times10\times9\times8\times7=55440\) इसलिए (n=11) है।
