यदि (\frac{(n+4)!}{(n+2)!}=156) है तो (n) का मान क्या है?
If (\frac{(n+4)!}{(n+2)!}=156) then what is the value of (n)?
Explanation opens after your attempt
B. (9)
Concept
We get ((n+4)(n+3)=156). Since \(13\times12=156\), (n=9).
Why this answer is correct
The correct answer is B. (9). We get ((n+4)(n+3)=156). Since \(13\times12=156\), (n=9).
Exam Tip
((n+4)(n+3)=156) मिलता है। \(13\times12=156\) इसलिए (n=9) है।
