यदि \(U=\{1,2,3,4,5,6,7\}\) और \(A^c={1,7}\) है, तो (A) क्या होगा?
If \(U=\{1,2,3,4,5,6,7\}\) and \(A^c={1,7}\), what is (A)?
Explanation opens after your attempt
A. ({2,3,4,5,6})
Concept
(A) contains the elements of (U) that are not in \(A^c\). So remove (1) and (7) and write the remaining elements.
Why this answer is correct
The correct answer is A. ({2,3,4,5,6}). (A) contains the elements of (U) that are not in \(A^c\). So remove (1) and (7) and write the remaining elements.
Exam Tip
(A) में (U) के वे तत्व होंगे जो \(A^c\) में नहीं हैं। इसलिए (1) और (7) हटाकर बाकी तत्व लिखें।
