यदि \(A=\{1,2,3\}\), \(B=\{1,2,3,4\}\) और \(C=\{(a,b)\in A\times B:\operatorname{lcm}(a,b)=6\}\), तो (C) कौन सा है?
If \(A=\{1,2,3\}\), \(B=\{1,2,3,4\}\), and \(C=\{(a,b)\in A\times B:\operatorname{lcm}(a,b)=6\}\), which is (C)?
Explanation opens after your attempt
Correct Answer
A. ({(2,3),(3,2)})
Concept
Only ((2,3)) and ((3,2)) have (\operatorname{lcm}(a,b)=6). Remember that (6) is not in the second set (B).
Why this answer is correct
The correct answer is A. ({(2,3),(3,2)}). Only ((2,3)) and ((3,2)) have (\operatorname{lcm}(a,b)=6). Remember that (6) is not in the second set (B).
Exam Tip
केवल ((2,3)) और ((3,2)) के लिए (\operatorname{lcm}(a,b)=6) है। ध्यान रखें कि (6) दूसरे समुच्चय (B) में नहीं है।
