यह ((n+5)(n+4)(n+3)(n+2)=11880) देता है। \(12\cdot11\cdot10\cdot9=11880\), इसलिए (n=7)। / It gives ((n+5)(n+4)(n+3)(n+2)=11880). Since \(12\cdot11\cdot10\cdot9=11880\), (n=7).
Mathematics Answer, Explanation and Revision Hints
यदि ( \frac{(n+5)!}{(n+1)!}=11880 ), तो (n) का मान क्या है? / If ( \frac{(n+5)!}{(n+1)!}=11880 ), what is the value of (n)?
Correct Answer: B. (7). Explanation: यह ((n+5)(n+4)(n+3)(n+2)=11880) देता है। \(12\cdot11\cdot10\cdot9=11880\), इसलिए (n=7)। / It gives ((n+5)(n+4)(n+3)(n+2)=11880). Since \(12\cdot11\cdot10\cdot9=11880\), (n=7).
