On (A={1,2,3,4}), (R={(a,b):a+b\text{ is even}}). What is (R)?समुच्चय (A={1,2,3,4}) पर (R={(a,b):a+b\text{ सम है}}) है। (R) कैसा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Symmetricसममित
Step 1: Look at the condition that (a+b) is even. Step 2: If (a+b) is even, then (b+a) is also even because changing order does not change the sum. Step 3: In sum-based conditions, reverse pairs are easy to verify.चरण 1: (a+b) सम होने की शर्त देखें। चरण 2: यदि (a+b) सम है, तो (b+a) भी सम है क्योंकि जोड़ का क्रम बदलने से योग नहीं बदलता। चरण 3: योग वाली शर्तों में उलटा युग्म जल्दी पहचानें।
