\(यदि (U=\mathbb{N}) और (A={x:x \in \mathbb{N}\) तथा x विषम है}), तो (A') क्या है?
\(If (U=\mathbb{N}) and (A={x:x \in \mathbb{N}\) and x is odd}), what is (A')?
Explanation opens after your attempt
Correct Answer
A. \(({x:x \in \mathbb{N}\) and x is even})
Concept
The complement is always taken inside the given (U). Thus (A') is the set of natural even numbers here.
Why this answer is correct
\(The correct answer is A. ({x:x \in \mathbb{N}\) and x is even}). The complement is always taken inside the given (U). Thus (A') is the set of natural even numbers here.
Exam Tip
पूरक हमेशा दिए गए (U) के अंदर ही लिया जाता है। इसलिए यहाँ (A') प्राकृतिक सम संख्याओं का समुच्चय है।
