On (A={1,2,3,4}), in the relation (R={(a,b):a+b\text{ is odd}}), which pair must occur with ((1,2))?(A={1,2,3,4}) पर (R={(a,b):a+b\text{ विषम है}}) संबंध में ((1,2)) के साथ कौन-सा युग्म अवश्य होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((2,1))((2,1))
Step 1: (1+2=3), which is odd, so ((1,2)) belongs to the relation. Step 2: (2+1=3) is also odd, so ((2,1)) also belongs. Step 3: In sum-based rules, the reverse pair usually satisfies the same condition.चरण 1: (1+2=3), जो विषम है, इसलिए ((1,2)) संबंध में है। चरण 2: (2+1=3) भी विषम है, इसलिए ((2,1)) भी संबंध में होगा। चरण 3: योग वाले नियम में उलटा युग्म प्रायः उसी शर्त को पूरा करता है।
