यदि \(A={x:x\in \mathbb{N}, 3\leq x<7}\) है तो कौन सा (A) का उचित उपसमुच्चय है?
If \(A={x:x\in \mathbb{N}, 3\leq x<7}\) then which is a proper subset of (A)?
Explanation opens after your attempt
Correct Answer
A. ({3,5,6})
Concept
\(A=\{3,4,5,6\}\), and ({3,5,6}) lies inside it but is not equal. A proper subset misses at least one element.
Why this answer is correct
The correct answer is A. ({3,5,6}). \(A=\{3,4,5,6\}\), and ({3,5,6}) lies inside it but is not equal. A proper subset misses at least one element.
Exam Tip
\(A=\{3,4,5,6\}\) है और ({3,5,6}) इसमें पूरा है पर बराबर नहीं। उचित उपसमुच्चय में कम से कम एक अवयव छूटता है।
