यदि ( \frac{(n+3)!}{(n+1)!}=72 ), तो (n) का मान क्या होगा?

If ( \frac{(n+3)!}{(n+1)!}=72 ), what will be the value of (n)?

Explanation opens after your attempt
Correct Answer

B. (6)

Step 1

Concept

It is ((n+3)(n+2)=72), so \(9\cdot8=72\) gives (n=6). Match consecutive factors.

Step 2

Why this answer is correct

The correct answer is B. (6). It is ((n+3)(n+2)=72), so \(9\cdot8=72\) gives (n=6). Match consecutive factors.

Step 3

Exam Tip

यह ((n+3)(n+2)=72) है, इसलिए \(9\cdot8=72\) से (n=6) है। लगातार गुणकों को मिलाकर देखें।
