यदि \(A=\{1,2,3,4,5\}\) और \(B=\{2,4,6\}\) है, तो \(A\cap (A-B)\) क्या है?
If \(A=\{1,2,3,4,5\}\) and \(B=\{2,4,6\}\), what is \(A\cap (A-B)\)?
Explanation opens after your attempt
A. ( {1,3,5} )
Concept
First (A-B={1,3,5}), and it is already a part of (A). Therefore the intersection is ({1,3,5}).
Why this answer is correct
The correct answer is A. ( {1,3,5} ). First (A-B={1,3,5}), and it is already a part of (A). Therefore the intersection is ({1,3,5}).
Exam Tip
पहले (A-B={1,3,5}) है और यह (A) का ही भाग है। इसलिए प्रतिच्छेद ({1,3,5}) है।
