यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{2,4,6,8\}\) और \(B=\{1,2,3,4\}\) है, तो (\(A\cap B\)') क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{2,4,6,8\}\), and \(B=\{1,2,3,4\}\), what will (\(A\cap B\)') be?
Explanation opens after your attempt
Correct Answer
A. ({1,3,5,6,7,8,9,10})
Concept
\(A\cap B={2,4}\), so its complement is (U-{2,4}). Take complement only after finding the intersection.
Why this answer is correct
The correct answer is A. ({1,3,5,6,7,8,9,10}). \(A\cap B={2,4}\), so its complement is (U-{2,4}). Take complement only after finding the intersection.
Exam Tip
\(A\cap B={2,4}\), इसलिए इसका पूरक (U-{2,4}) है। प्रतिच्छेद के बाद ही पूरक लें।
