यदि \(U=\{1,2,3,4,5,6,7\}\) और \(A=\{2,4,6\}\) है, तो ऐसा (B) कौन सा होगा जिससे \(B^c=A\) सत्य हो?
If \(U=\{1,2,3,4,5,6,7\}\) and \(A=\{2,4,6\}\), which (B) makes \(B^c=A\) true?
Explanation opens after your attempt
Correct Answer
A. ({1,3,5,7})
Concept
If \(B^c=A\), then \(B=A^c\). Removing (2,4,6) from (U) gives \(B=\{1,3,5,7\}\).
Why this answer is correct
The correct answer is A. ({1,3,5,7}). If \(B^c=A\), then \(B=A^c\). Removing (2,4,6) from (U) gives \(B=\{1,3,5,7\}\).
Exam Tip
यदि \(B^c=A\), तो \(B=A^c\) होगा। (U) से (2,4,6) हटाने पर \(B=\{1,3,5,7\}\) मिलता है।
