यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,3,4\}\) और \(A^{c}\subseteq B\) है, तो (B) में कम से कम कौन से अवयव होने चाहिए?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\), \(A=\{1,2,3,4\}\), and \(A^{c}\subseteq B\), which elements must at least be in (B)?
Explanation opens after your attempt
Correct Answer
B. ({5,6,7,8,9,10})
Concept
\(A^{c}={5,6,7,8,9,10}\), and it is a subset of (B). Hence all these elements must be in (B).
Why this answer is correct
The correct answer is B. ({5,6,7,8,9,10}). \(A^{c}={5,6,7,8,9,10}\), and it is a subset of (B). Hence all these elements must be in (B).
Exam Tip
\(A^{c}={5,6,7,8,9,10}\), और यह (B) का उपसमुच्चय है। इसलिए ये सभी अवयव (B) में होने जरूरी हैं।
