यदि \(A=\{1,2,3,4,5\}\) और \(R=\{(x,y):y=2x\}\), जहां \(x,y\in A\), तो (R) का परिसर क्या है?
If \(A=\{1,2,3,4,5\}\) and \(R=\{(x,y):y=2x\}\), where \(x,y\in A\), what is the range of (R)?
Explanation opens after your attempt
A. ({2,4})
Concept
For (x=1), (y=2), and for (x=2), (y=4); after that \(y\notin A\). So the range is ({2,4}).
Why this answer is correct
The correct answer is A. ({2,4}). For (x=1), (y=2), and for (x=2), (y=4); after that \(y\notin A\). So the range is ({2,4}).
Exam Tip
(x=1) पर (y=2) और (x=2) पर (y=4) मिलता है; आगे \(y\notin A\) हो जाता है। इसलिए परिसर ({2,4}) है।
