In (R={(1,2),(2,3),(1,3)}), which pair is needed because of ((1,2)) and ((2,3))?(R={(1,2),(2,3),(1,3)}) में ((1,2)) और ((2,3)) के कारण कौन सा युग्म चाहिए?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((1,3))((1,3))
Step 1: The transitive rule says ((a,b)) and ((b,c)) require ((a,c)). Step 2: From ((1,2)) and ((2,3)), the required pair is ((1,3)). Step 3: Remove the common middle element and join the first and last elements.चरण 1: संचारी नियम कहता है कि ((a,b)) और ((b,c)) से ((a,c)) चाहिए। चरण 2: ((1,2)) और ((2,3)) से ((1,3)) चाहिए। चरण 3: बीच का (2) हटाकर पहला और अंतिम अवयव मिलाएँ।
