यदि ( \frac{(2n+1)!}{(2n-1)!}=272 ), तो (n) का मान क्या है?
If ( \frac{(2n+1)!}{(2n-1)!}=272 ), what is the value of (n)?
Explanation opens after your attempt
C. (8)
Concept
It is ((2n+1)(2n)=272), and \(17\cdot16=272\), so (2n=16) and (n=8). Identify the consecutive factors first.
Why this answer is correct
The correct answer is C. (8). It is ((2n+1)(2n)=272), and \(17\cdot16=272\), so (2n=16) and (n=8). Identify the consecutive factors first.
Exam Tip
यह ((2n+1)(2n)=272) है और \(17\cdot16=272\), इसलिए (2n=16) और (n=8)। पहले लगातार गुणकों को पहचानें।
