If (R={(1,2),(2,4),(3,4)}), which pair must be in (R^{-1})?यदि (R={(1,2),(2,4),(3,4)}), तो (R^{-1}) में कौन सा युग्म अवश्य होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Both ((4,2)) and ((4,3))((4,2)) और ((4,3)) दोनों
Step 1: In an inverse relation, the two entries of every pair are interchanged. Step 2: ((2,4)) gives ((4,2)), and ((3,4)) gives ((4,3)). Step 3: Reverse every pair separately while finding the inverse.चरण 1: विलोम संबंध में हर युग्म के दोनों स्थान बदलते हैं। चरण 2: ((2,4)) से ((4,2)) और ((3,4)) से ((4,3)) मिलते हैं। चरण 3: विलोम निकालते समय सभी युग्मों को अलग-अलग उलटें।
