यदि ( \frac{(n+6)!}{(n+3)!}-\frac{(n+5)!}{(n+2)!}=546 ), तो (n) का मान क्या है?

If ( \frac{(n+6)!}{(n+3)!}-\frac{(n+5)!}{(n+2)!}=546 ), what is the value of (n)?

Explanation opens after your attempt
Correct Answer

B. (8)

Step 1

Concept

The simplified form is (3(n+5)(n+4)). Since \(3\cdot13\cdot12=468\) is wrong and \(3\cdot14\cdot13=546\), (n=8).

Step 2

Why this answer is correct

The correct answer is B. (8). The simplified form is (3(n+5)(n+4)). Since \(3\cdot13\cdot12=468\) is wrong and \(3\cdot14\cdot13=546\), (n=8).

Step 3

Exam Tip

सरल रूप (3(n+5)(n+4)) है। \(3\cdot13\cdot12=468\) नहीं, सही \(3\cdot14\cdot13=546\) से (n=8) मिलता है।
