यदि \(A=\{1,2,3,4,5,6,7\}\), \(B=\{2,4,6,8\}\) और \(C=\{1,4,7,8\}\), तो (\(A\cup B\)\cap C) क्या है?
If \(A=\{1,2,3,4,5,6,7\}\), \(B=\{2,4,6,8\}\), and \(C=\{1,4,7,8\}\), what is (\(A\cup B\)\cap C)?
Explanation opens after your attempt
Correct Answer
A. ({1,4,7,8})
Concept
\(A\cup B={1,2,3,4,5,6,7,8}\). Its intersection with (C) gives the whole \(C=\{1,4,7,8\}\).
Why this answer is correct
The correct answer is A. ({1,4,7,8}). \(A\cup B={1,2,3,4,5,6,7,8}\). Its intersection with (C) gives the whole \(C=\{1,4,7,8\}\).
Exam Tip
\(A\cup B={1,2,3,4,5,6,7,8}\) है। इसका (C) से प्रतिच्छेद पूरा \(C=\{1,4,7,8\}\) देता है।
