यदि \(A=\{1,2,3,4,5\}\), \(B=\{2,4,6,8\}\) और \(C=\{1,4,7,8\}\) हैं, तो (\(A\cup B\)\cap C) क्या है?
If \(A=\{1,2,3,4,5\}\), \(B=\{2,4,6,8\}\) and \(C=\{1,4,7,8\}\), what is (\(A\cup B\)\cap C)?
Explanation opens after your attempt
A. ({1,4,8})
Concept
First \(A\cup B={1,2,3,4,5,6,8}\), then common elements with (C) are ({1,4,8}). Always follow the brackets.
Why this answer is correct
The correct answer is A. ({1,4,8}). First \(A\cup B={1,2,3,4,5,6,8}\), then common elements with (C) are ({1,4,8}). Always follow the brackets.
Exam Tip
पहले \(A\cup B={1,2,3,4,5,6,8}\) है, फिर (C) के साथ सामान्य तत्व ({1,4,8}) हैं। कोष्ठक का क्रम हमेशा ध्यान रखें।
