यदि ( \frac{(n+4)!+(n+3)!}{(n+2)!}=143 ), तो (n) का मान क्या होगा?

If ( \frac{(n+4)!+(n+3)!}{(n+2)!}=143 ), what will be the value of (n)?

Explanation opens after your attempt
Correct Answer

B. (8)

Step 1

Concept

The simplified form is ((n+3)(n+5)). Since \(11\cdot13=143\), (n=8).

Step 2

Why this answer is correct

The correct answer is B. (8). The simplified form is ((n+3)(n+5)). Since \(11\cdot13=143\), (n=8).

Step 3

Exam Tip

सरल रूप ((n+3)(n+5)) है। \(11\cdot13=143\), इसलिए (n=8)।
