यदि \(A={x:x\in \mathbb{N},x<8}\) और \(B={x:x\in \mathbb{N},x>4,x<10}\) हैं, तो \(A\setminus B\) क्या है?
If \(A={x:x\in \mathbb{N},x<8}\) and \(B={x:x\in \mathbb{N},x>4,x<10}\), what is \(A\setminus B\)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3,4} )
Concept
\(A=\{1,2,3,4,5,6,7\}\) and \(B=\{5,6,7,8,9\}\), so \(A\setminus B={1,2,3,4}\). Read boundary signs carefully.
Why this answer is correct
The correct answer is A. ( {1,2,3,4} ). \(A=\{1,2,3,4,5,6,7\}\) and \(B=\{5,6,7,8,9\}\), so \(A\setminus B={1,2,3,4}\). Read boundary signs carefully.
Exam Tip
\(A=\{1,2,3,4,5,6,7\}\) और \(B=\{5,6,7,8,9\}\), इसलिए \(A\setminus B={1,2,3,4}\)। सीमा चिन्हों को ध्यान से पढ़ें।
