यदि \(A={x:x\in \mathbb{N},x\leq 3}\) है तो कौन सा विकल्प (A) का उचित उपसमुच्चय है?
If \(A={x:x\in \mathbb{N},x\leq 3}\) then which option is a proper subset of (A)?
Explanation opens after your attempt
Correct Answer
A. ({1,2})
Concept
Here \(A=\{1,2,3\}\) and ({1,2}) is its proper subset. A proper subset is not equal to the whole set.
Why this answer is correct
The correct answer is A. ({1,2}). Here \(A=\{1,2,3\}\) and ({1,2}) is its proper subset. A proper subset is not equal to the whole set.
Exam Tip
यहां \(A=\{1,2,3\}\) है और ({1,2}) इसका उचित उपसमुच्चय है। उचित उपसमुच्चय पूरे समुच्चय के बराबर नहीं होता।
