यदि \(U={x:x\in \mathbb{N},x\le 9}\) और \(S=\{1,4,9\}\) है, तो (S') क्या होगा?
If \(U={x:x\in \mathbb{N},x\le 9}\) and \(S=\{1,4,9\}\), what will (S') be?

Correct Answer
A. ({2,3,5,6,7,8})
Concept
(S) has (1,4,9), so the remaining elements of (U), (2,3,5,6,7,8), are in the complement. Writing \(U={1,2,\ldots,9}\) first helps.
Why this answer is correct
The correct answer is A. ({2,3,5,6,7,8}). (S) has (1,4,9), so the remaining elements of (U), (2,3,5,6,7,8), are in the complement. Writing \(U={1,2,\ldots,9}\) first helps.
Exam Tip
(S) में (1,4,9) हैं, इसलिए (U) के बाकी (2,3,5,6,7,8) पूरक हैं। पहले \(U={1,2,\ldots,9}\) लिखना सहायक है।
