यदि \(A=\{4,6,8\}\) और \(B=\{1,2,4\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (y) संख्या (x) को विभाजित करती है?
If \(A=\{4,6,8\}\) and \(B=\{1,2,4\}\), how many pairs ((x,y)) in \(A\times B\) satisfy that (y) divides (x)?
Explanation opens after your attempt
A. (8)
Concept
The valid pairs are ((4,1),(4,2),(4,4),(6,1),(6,2),(8,1),(8,2),(8,4)). In divisibility, note the positions of divisor and dividend carefully.
Why this answer is correct
The correct answer is A. (8). The valid pairs are ((4,1),(4,2),(4,4),(6,1),(6,2),(8,1),(8,2),(8,4)). In divisibility, note the positions of divisor and dividend carefully.
