यदि \(A=\{p,q\}\) और \(B=\{p,q,r\}\) है, तो \(A\cap B\) क्या है?
If \(A=\{p,q\}\) and \(B=\{p,q,r\}\), what is \(A\cap B\)?
Explanation opens after your attempt
Correct Answer
A. ( {p,q} )
Concept
All elements of (A) are in (B), so \(A\cap B=A\). In subset cases, the smaller set is the intersection.
Why this answer is correct
The correct answer is A. ( {p,q} ). All elements of (A) are in (B), so \(A\cap B=A\). In subset cases, the smaller set is the intersection.
Exam Tip
क्योंकि (A) के सभी अवयव (B) में हैं, इसलिए \(A\cap B=A\) है। उपसमुच्चय में प्रतिच्छेद छोटा समुच्चय होता है।
