यदि ( \frac{(n+4)!}{n!}=11880 ), तो (n) का मान क्या होगा?
If ( \frac{(n+4)!}{n!}=11880 ), what will be the value of (n)?
Explanation opens after your attempt
C. (8)
Concept
It is ((n+4)(n+3)(n+2)(n+1)=11880), and \(12\cdot11\cdot10\cdot9=11880\). So (n=8).
Why this answer is correct
The correct answer is C. (8). It is ((n+4)(n+3)(n+2)(n+1)=11880), and \(12\cdot11\cdot10\cdot9=11880\). So (n=8).
Exam Tip
यह ((n+4)(n+3)(n+2)(n+1)=11880) है और \(12\cdot11\cdot10\cdot9=11880\)। इसलिए (n=8) है।
