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