यदि \(A=\{1,2,3\}\) और \(R=\{(1,1),(2,2),(3,3),(1,2),(2,3)\}\) है, तो (R) को संक्रमणीय बनाने के लिए न्यूनतम कौन सा युग्म जोड़ना होगा?
If \(A=\{1,2,3\}\) and \(R=\{(1,1),(2,2),(3,3),(1,2),(2,3)\}\), which minimum pair must be added to make (R) transitive?
Explanation opens after your attempt
Correct Answer
A. ((1,3))
Concept
From ((1,2)) and ((2,3)), the pair ((1,3)) is required. The needed diagonal pairs are already present.
Why this answer is correct
The correct answer is A. ((1,3)). From ((1,2)) and ((2,3)), the pair ((1,3)) is required. The needed diagonal pairs are already present.
Exam Tip
