यदि \(A=\{1,2,3\}\) और \(B=\{4,5\}\) हैं, तो कौन सा समुच्चय (A) से (B) तक संबंध हो सकता है?
If \(A=\{1,2,3\}\) and \(B=\{4,5\}\), which set can be a relation from (A) to (B)?
Explanation opens after your attempt
Correct Answer
A. ( {(1,4),(3,5)} )
Concept
A relation from (A) to (B) must be a subset of \(A\times B\). So first components must come from (A), and second components must come from (B).
Why this answer is correct
The correct answer is A. ( {(1,4),(3,5)} ). A relation from (A) to (B) must be a subset of \(A\times B\). So first components must come from (A), and second components must come from (B).
Exam Tip
(A) से (B) तक संबंध \(A\times B\) का उपसमुच्चय होना चाहिए। इसलिए पहले घटक (A) से और दूसरे घटक (B) से होने चाहिए।
