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)?
Explanation opens after your attempt
B. (7)
Concept
It gives ((n+5)(n+4)(n+3)(n+2)=11880). Since \(12\cdot11\cdot10\cdot9=11880\), (n=7).
Why this answer is correct
The correct answer is B. (7). It gives ((n+5)(n+4)(n+3)(n+2)=11880). Since \(12\cdot11\cdot10\cdot9=11880\), (n=7).
Exam Tip
यह ((n+5)(n+4)(n+3)(n+2)=11880) देता है। \(12\cdot11\cdot10\cdot9=11880\), इसलिए (n=7)।
