\(यदि (U={x:x \in \mathbb{Z}, -3 \le x \le 7}) और (A={x:x \in U\) तथा \(x+2>4}), तो (A') क्या है\)?
\(If (U={x:x \in \mathbb{Z}, -3 \le x \le 7}) and (A={x:x \in U\) and \(x+2>4}), what is (A')\)?
Explanation opens after your attempt
A. ({-3,-2,-1,0,1,2})
Concept
(x+2>4) gives (x>2), so \(A=\{3,4,5,6,7\}\). The complement contains the remaining integers.
Why this answer is correct
The correct answer is A. ({-3,-2,-1,0,1,2}). (x+2>4) gives (x>2), so \(A=\{3,4,5,6,7\}\). The complement contains the remaining integers.
Exam Tip
(x+2>4) से (x>2) मिलता है, इसलिए \(A=\{3,4,5,6,7\}\) है। पूरक बाकी पूर्णांक हैं।
