\(यदि (U={1,2,\ldots,25}), (A={x:x\) पूर्ण वर्ग है\(}) और (B={x:x\) 5 का गुणज है\(}), तो (A'\cap B') में कौन सा अवयव होगा\)?
\(If (U={1,2,\ldots,25}), (A={x:x\) is a perfect square\(}) and (B={x:x\) is a multiple of \(5}), which element belongs to (A'\cap B')\)?
Explanation opens after your attempt
Correct Answer
C. (22)
Concept
\(A'\cap B'\) contains elements that are neither perfect squares nor multiples of (5). (22) satisfies both conditions.
Why this answer is correct
The correct answer is C. (22). \(A'\cap B'\) contains elements that are neither perfect squares nor multiples of (5). (22) satisfies both conditions.
Exam Tip
\(A'\cap B'\) में वे अवयव होते हैं जो न पूर्ण वर्ग हैं और न (5) के गुणज। (22) इन दोनों शर्तों को पूरा करता है।
