यदि \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\) और \(C=\{1,2,4\}\), तो (\(A\cap C\)\times\(B\cap C\)) में कितने तत्व हैं?
If \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\), and \(C=\{1,2,4\}\), how many elements are in (\(A\cap C\)\times\(B\cap C\))?
Explanation opens after your attempt
Correct Answer
B. (6)
Concept
\(A\cap C={1,2,4}\) and \(B\cap C={2,4}\). Therefore the total number of pairs is \(3\cdot2=6\).
Why this answer is correct
The correct answer is B. (6). \(A\cap C={1,2,4}\) and \(B\cap C={2,4}\). Therefore the total number of pairs is \(3\cdot2=6\).
Exam Tip
\(A\cap C={1,2,4}\) और \(B\cap C={2,4}\) हैं। इसलिए कुल \(3\cdot2=6\) युग्म हैं।
