यदि ( \frac{(n+6)!}{(n+4)!}+\frac{(n+5)!}{(n+3)!}=338 ), तो (n) का मान क्या है?

If ( \frac{(n+6)!}{(n+4)!}+\frac{(n+5)!}{(n+3)!}=338 ), what is the value of (n)?

Explanation opens after your attempt
Correct Answer

A. (8)

Step 1

Concept

The simplified form is (2(n+5)2). From (2(n+5)2=338), (n+5=13), so (n=8).

Step 2

Why this answer is correct

The correct answer is A. (8). The simplified form is (2(n+5)2). From (2(n+5)2=338), (n+5=13), so (n=8).

Step 3

Exam Tip

सरल रूप (2(n+5)2) है। (2(n+5)2=338) से (n+5=13), इसलिए (n=8)।
