यदि ( \frac{(2n+2)!}{(2n)!}=132 ), तो (n) का मान क्या है?
If ( \frac{(2n+2)!}{(2n)!}=132 ), what is the value of (n)?
Explanation opens after your attempt
D. (5)
Concept
It gives ((2n+2)(2n+1)=132), and \(12\cdot11=132\), so (n=5). Match the consecutive factors first.
Why this answer is correct
The correct answer is D. (5). It gives ((2n+2)(2n+1)=132), and \(12\cdot11=132\), so (n=5). Match the consecutive factors first.
Exam Tip
यह ((2n+2)(2n+1)=132) देता है और \(12\cdot11=132\), इसलिए (n=5)। पहले लगातार गुणकों को मिलाएं।
