\(यदि (U={1,2,\ldots,24}), (A={x:x\) 2 से विभाज्य है\(}), (B={x:x\) 3 से विभाज्य है\(}), तो (|A'\cup B'|) कितना है\)?
\(If (U={1,2,\ldots,24}), (A={x:x\) is divisible by \(2}), (B={x:x\) is divisible by \(3}), what is (|A'\cup B'|)\)?
Explanation opens after your attempt
C. (20)
Concept
(A'\cup B'=\(A\cap B\)'). \(A\cap B\) has (4) multiples of (6), so the count is (24-4=20).
Why this answer is correct
The correct answer is C. (20). (A'\cup B'=\(A\cap B\)'). \(A\cap B\) has (4) multiples of (6), so the count is (24-4=20).
Exam Tip
(A'\cup B'=\(A\cap B\)')। \(A\cap B\) में (6) के (4) गुणज हैं, इसलिए संख्या (24-4=20) है।
