यदि \(A={x:x\in\mathbb{N}\) और \(x^2<50}\) तो (A) का कौन सा उपसमुच्चय नहीं है?
If \(A={x:x\in\mathbb{N}\) and \(x^2<50}\), which is not a subset of (A)?

Correct Answer
C. ({1,5,8})
Concept
Here \(A=\{1,2,3,4,5,6,7\}\), and (8) is not in it. One outside element makes the subset statement false.
Why this answer is correct
The correct answer is C. ({1,5,8}). Here \(A=\{1,2,3,4,5,6,7\}\), and (8) is not in it. One outside element makes the subset statement false.
Exam Tip
\(A=\{1,2,3,4,5,6,7\}\) है और (8) इसमें नहीं है। एक बाहरी अवयव पूरा उपसमुच्चय कथन गलत कर देता है।
