यदि \(A=\{2,4,6,8\}\) और \(B=\{4,8,12\}\) है, तो कौन सा अवयव \(A\cap B\) में है?
If \(A=\{2,4,6,8\}\) and \(B=\{4,8,12\}\), which element is in \(A\cap B\)?
Explanation opens after your attempt
B. (4)
Concept
(4) is in both sets, so it is in \(A\cap B\). For intersection, an element must be in both sets.
Why this answer is correct
The correct answer is B. (4). (4) is in both sets, so it is in \(A\cap B\). For intersection, an element must be in both sets.
Exam Tip
(4) दोनों समुच्चयों में है, इसलिए वह \(A\cap B\) में है। प्रतिच्छेद के लिए अवयव दोनों में होना चाहिए।
