यदि \(U={x:x \in \mathbb{Z},-6\le x\le 12}\) और \(A={x:x \in U,2x-3<7}\), तो (A') क्या है?
If \(U={x:x \in \mathbb{Z},-6\le x\le 12}\) and \(A={x:x \in U,2x-3<7}\), what is (A')?
Explanation opens after your attempt
A. ({5,6,7,8,9,10,11,12})
Concept
(2x-3<7) gives (x<5). Therefore the complement contains elements with \(x\ge 5\).
Why this answer is correct
The correct answer is A. ({5,6,7,8,9,10,11,12}). (2x-3<7) gives (x<5). Therefore the complement contains elements with \(x\ge 5\).
Exam Tip
(2x-3<7) से (x<5) मिलता है। इसलिए पूरक में \(x\ge 5\) वाले सदस्य आएंगे।
