यदि \(A=\{2,3,5,7,11,13\}\) और \(B={x\in A:x>5}\), तो \(A\cap B\) क्या है?
If \(A=\{2,3,5,7,11,13\}\) and \(B={x\in A:x>5}\), what is \(A\cap B\)?
Explanation opens after your attempt
A. ({7,11,13})
Concept
(B) is a subset of (A) containing elements greater than (5). Therefore \(A\cap B=B={7,11,13}\).
Why this answer is correct
The correct answer is A. ({7,11,13}). (B) is a subset of (A) containing elements greater than (5). Therefore \(A\cap B=B={7,11,13}\).
Exam Tip
(B), (A) का उपसमुच्चय है जिसमें (5) से बड़े तत्व हैं। इसलिए \(A\cap B=B={7,11,13}\)।
