यदि \(A=\{6,8\}\) और \(B=\{1,3,5\}\) हैं, तो दूसरे घटक (5) वाले \(A\times B\) के युग्म कौन से हैं?
If \(A=\{6,8\}\) and \(B=\{1,3,5\}\), which pairs of \(A\times B\) have second component (5)?
Explanation opens after your attempt
A. ({(6,5),(8,5)})
Concept
The second component (5) is fixed and the first component is (6) or (8) from (A). In such questions, do not change the position of the fixed component.
Why this answer is correct
The correct answer is A. ({(6,5),(8,5)}). The second component (5) is fixed and the first component is (6) or (8) from (A). In such questions, do not change the position of the fixed component.
Exam Tip
दूसरा घटक (5) स्थिर है और पहला घटक (A) से (6) या (8) होगा। ऐसे प्रश्नों में तय घटक की जगह न बदलें।
