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
Correct Answer

C. (7)

Step 1

Concept

The expression becomes (2(n+3)2), so (2(n+3)2=200). Thus (n+3=10) and (n=7).

Step 2

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).

Step 3

Exam Tip

अभिव्यक्ति (2(n+3)2) बनती है, इसलिए (2(n+3)2=200)। इससे (n+3=10) और (n=7)।
