If (R={(2,4),(4,2),(4,4)}), which pair is its own reverse?यदि (R={(2,4),(4,2),(4,4)}), तो कौन-सा युग्म अपना ही उलटा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((4,4))((4,4))
Step 1: A pair is its own reverse when both entries are the same. Step 2: Reversing ((4,4)) gives ((4,4)). Step 3: Recognize such pairs as diagonal pairs.चरण 1: अपना ही उलटा वही युग्म होता है जिसमें दोनों स्थानों पर समान तत्व हों। चरण 2: ((4,4)) को उलटने पर ((4,4)) ही मिलता है। चरण 3: ऐसे युग्मों को विकर्ण युग्म कहकर पहचानें।
