यदि \(A=\{1,2,3\}\) और \(B=\{2,4,6,8\}\), \(R=\{(a,b):b=2a\}\) है, तो (R) क्या है?
If \(A=\{1,2,3\}\), \(B=\{2,4,6,8\}\), and \(R=\{(a,b):b=2a\}\), what is (R)?
Explanation opens after your attempt
Correct Answer
A. ( {(1,2),(2,4),(3,6)} )
Concept
Take the first component from (A) and the second from (B), then apply (b=2a). This gives ( (1,2),(2,4),(3,6) ).
Why this answer is correct
The correct answer is A. ( {(1,2),(2,4),(3,6)} ). Take the first component from (A) and the second from (B), then apply (b=2a). This gives ( (1,2),(2,4),(3,6) ).
Exam Tip
पहला घटक (A) से और दूसरा (B) से लेकर (b=2a) लगाते हैं। इससे ( (1,2),(2,4),(3,6) ) मिलते हैं।
