Mathematics Answer, Explanation and Revision Hints
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)?
Correct Answer: C. (12). Explanation: ऊपर ((n+2)!((n+3)-1)) बनता है। इसलिए मान ((n+2)2=196) से (n=12) मिलता है। / The numerator becomes ((n+2)!((n+3)-1)). So ((n+2)2=196) gives (n=12).
