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
B. (8)
Concept
The simplified form is ((n+3)(n+5)). Since \(11\cdot13=143\), (n=8).
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).
Exam Tip
सरल रूप ((n+3)(n+5)) है। \(11\cdot13=143\), इसलिए (n=8)।
