यदि \(A=\{1,2,5\}\) और \(B=\{2,6\}\) हैं, तो \(A\times B\) में दोनों घटकों का गुणनफल (10) से अधिक होने वाले कितने युग्म हैं?
If \(A=\{1,2,5\}\) and \(B=\{2,6\}\), how many pairs in \(A\times B\) have product of both components greater than (10)?
Explanation opens after your attempt
B. (2)
Concept
The pairs are ((2,6)) and ((5,6)), whose products are greater than (10). In condition-based questions, quickly check all possible pairs.
Why this answer is correct
The correct answer is B. (2). The pairs are ((2,6)) and ((5,6)), whose products are greater than (10). In condition-based questions, quickly check all possible pairs.
Exam Tip
