यदि \(R=\{(1,2),(2,3),(3,3)\}\), तो \(R^{-1}\) क्या होगा?
If \(R=\{(1,2),(2,3),(3,3)\}\), what is \(R^{-1}\)?
Correct answer and explanation
A. ({(2,1),(3,2),(3,3)})
Concept
विलोम संबंध में हर युग्म के दोनों स्थान बदलते हैं। / In the inverse relation, the two entries of each pair are interchanged.
Why this answer is correct
((1,2)) से ((2,1)), ((2,3)) से ((3,2)), और ((3,3)) वही रहता है। / ((1,2)) becomes ((2,1)), ((2,3)) becomes ((3,2)), and ((3,3)) remains the same.
Exam Tip
स्वयं युग्म विलोम लेने पर नहीं बदलता। / A self-pair does not change in the inverse.
