यदि \(A\cup B={2,4,6,8,10,12,14}\), (A-B={2,10}) और (B-A={6,14}) है, तो \(A\cap B\) क्या है?
If \(A\cup B={2,4,6,8,10,12,14}\), (A-B={2,10}), and (B-A={6,14}), what is \(A\cap B\)?
Explanation opens after your attempt
A. ({4,8,12})
Concept
The union is made of three disjoint parts (A-B), \(A\cap B\), and (B-A). Removing the given only-parts leaves ({4,8,12}).
Why this answer is correct
The correct answer is A. ({4,8,12}). The union is made of three disjoint parts (A-B), \(A\cap B\), and (B-A). Removing the given only-parts leaves ({4,8,12}).
Exam Tip
संघ तीन अलग भागों (A-B), \(A\cap B\) और (B-A) से बनता है। दिए गए केवल वाले भाग हटाने पर ({4,8,12}) बचता है।
