यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\) और \(A={x:x\in U,x\ge 7}\) है, तो (A') क्या होगा?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\) and \(A={x:x\in U,x\ge 7}\), what will (A') be?

Correct Answer
A. ({1,2,3,4,5,6})
Concept
(A) contains (7,8,9,10), so the complement is from (1) to (6). In \(x\ge 7\), (7) is also in (A).
Why this answer is correct
The correct answer is A. ({1,2,3,4,5,6}). (A) contains (7,8,9,10), so the complement is from (1) to (6). In \(x\ge 7\), (7) is also in (A).
Exam Tip
(A) में (7,8,9,10) हैं, इसलिए पूरक (1) से (6) तक है। \(x\ge 7\) में (7) भी (A) में आएगा।
