यदि \(A=\{1,2\}\), \(B=\{3,4\}\) और \(C=\{5,6\}\), तो (\(A\cup B\)\times C) में कितने तत्व हैं?

If \(A=\{1,2\}\), \(B=\{3,4\}\), and \(C=\{5,6\}\), how many elements are in (\(A\cup B\)\times C)?

Explanation opens after your attempt
Correct Answer

C. (8)

Step 1

Concept

\(A\cup B={1,2,3,4}\) has (4) elements and (C) has (2) elements. Hence \(4\cdot2=8\) pairs are formed.

Step 2

Why this answer is correct

The correct answer is C. (8). \(A\cup B={1,2,3,4}\) has (4) elements and (C) has (2) elements. Hence \(4\cdot2=8\) pairs are formed.

Step 3

Exam Tip

\(A\cup B={1,2,3,4}\) में (4) तत्व हैं और (C) में (2) तत्व हैं। इसलिए \(4\cdot2=8\) युग्म बनेंगे।
