यदि (\frac{(n+3)!-(n+2)!}{(n+1)!}=196) है तो (n) का मान क्या है?
If (\frac{(n+3)!-(n+2)!}{(n+1)!}=196) then what is the value of (n)?
Explanation opens after your attempt
C. (12)
Concept
The numerator becomes ((n+2)!((n+3)-1)). So ((n+2)2=196) gives (n=12).
Why this answer is correct
The correct answer is C. (12). The numerator becomes ((n+2)!((n+3)-1)). So ((n+2)2=196) gives (n=12).
Exam Tip
ऊपर ((n+2)!((n+3)-1)) बनता है। इसलिए मान ((n+2)2=196) से (n=12) मिलता है।
