यदि \(A={x:x\in N\) और \(x\le5}\) तथा \(B={x:x\in N\) और (x<5}) है तो कौन सा संबंध सही है?
If \(A={x:x\in N\) and \(x\le5}\) and \(B={x:x\in N\) and (x<5}) then which relation is correct?
Explanation opens after your attempt
Correct Answer
B. \(B\subset A\) और \(B\ne A\)\(B\subset A\) and \(B\ne A\)
Concept
(A) includes (5) but (B) does not, so (B) is a proper subset. In exams note the difference between \(\le\) and (<).
Why this answer is correct
The correct answer is B. \(B\subset A\) और \(B\ne A\) / \(B\subset A\) and \(B\ne A\). (A) includes (5) but (B) does not, so (B) is a proper subset. In exams note the difference between \(\le\) and (<).
Exam Tip
(A) में (5) शामिल है पर (B) में (5) नहीं है इसलिए (B) उचित उपसमुच्चय है। परीक्षा में \(\le\) और (<) का फर्क देखें।
