यह ((n+4)(n+3)(n+2)(n+1)=11880) है और \(12\cdot11\cdot10\cdot9=11880\)। इसलिए (n=8) है। / It is ((n+4)(n+3)(n+2)(n+1)=11880), and \(12\cdot11\cdot10\cdot9=11880\). So (n=8).
Mathematics Answer, Explanation and Revision Hints
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)?
Correct Answer: C. (8). Explanation: यह ((n+4)(n+3)(n+2)(n+1)=11880) है और \(12\cdot11\cdot10\cdot9=11880\)। इसलिए (n=8) है। / It is ((n+4)(n+3)(n+2)(n+1)=11880), and \(12\cdot11\cdot10\cdot9=11880\). So (n=8).
