यदि \(A=\{10,20\}\) और \(B=\{30,40,50\}\) हैं, तो \(A\times B\) में कुल कितने युग्म होंगे?

If \(A=\{10,20\}\) and \(B=\{30,40,50\}\), how many pairs are there in \(A\times B\)?

Explanation opens after your attempt
Correct Answer

B. (6)

Step 1

Concept

(A) has (2) elements and (B) has (3) elements, so \(2\times 3=6\). Count the elements first and then multiply.

Step 2

Why this answer is correct

The correct answer is B. (6). (A) has (2) elements and (B) has (3) elements, so \(2\times 3=6\). Count the elements first and then multiply.

Step 3

Exam Tip

(A) में (2) और (B) में (3) तत्व हैं, इसलिए \(2\times 3=6\)। पहले तत्व गिनें फिर गुणा करें।
