यदि ( \frac{(n+4)!}{(n+2)!}+\frac{(n+3)!}{(n+1)!}=200 ), तो (n) का मान क्या है?
If ( \frac{(n+4)!}{(n+2)!}+\frac{(n+3)!}{(n+1)!}=200 ), what is the value of (n)?
Explanation opens after your attempt
C. (7)
Concept
The expression becomes (2(n+3)2), so (2(n+3)2=200). Thus (n+3=10) and (n=7).
Why this answer is correct
The correct answer is C. (7). The expression becomes (2(n+3)2), so (2(n+3)2=200). Thus (n+3=10) and (n=7).
Exam Tip
अभिव्यक्ति (2(n+3)2) बनती है, इसलिए (2(n+3)2=200)। इससे (n+3=10) और (n=7)।
