On (A={1,2,3,4}), what type is the relation (R={(a,b):a+b=5})?(A={1,2,3,4}) पर (R={(a,b):a+b=5}) संबंध कैसा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Symmetricसममित
Step 1: If (a+b=5), then (b+a=5) also holds. Step 2: So the reverse pair ((b,a)) also belongs to the relation. Step 3: In sum-based rules, changing order does not change the rule.चरण 1: यदि (a+b=5), तो (b+a=5) भी होगा। चरण 2: इसलिए ((a,b)) का उलटा ((b,a)) भी संबंध में आएगा। चरण 3: योग वाले नियमों में क्रम बदलने से नियम नहीं बदलता।
