यदि \(A=\{2,3,5,7\}\), \(B=\{1,3,5,9\}\) और \(C=\{3,4,5\}\) हैं, तो (\(A\cap B\)\cup C) क्या है?
If \(A=\{2,3,5,7\}\), \(B=\{1,3,5,9\}\), and \(C=\{3,4,5\}\), what is (\(A\cap B\)\cup C)?
Explanation opens after your attempt
B. ( {3,4,5} )
Concept
\(A\cap B={3,5}\), and union with (C) gives ( {3,4,5} ). Find the bracket result first.
Why this answer is correct
The correct answer is B. ( {3,4,5} ). \(A\cap B={3,5}\), and union with (C) gives ( {3,4,5} ). Find the bracket result first.
Exam Tip
\(A\cap B={3,5}\), और (C) से संघ लेने पर ( {3,4,5} ) मिलता है। पहले कोष्ठक का परिणाम निकालें।
