यदि \(|A\times B|=24\), (|A|=4) और (|C|=7) हैं, तो \(|B\times C|\) का मान क्या होगा?

If \(|A\times B|=24\), (|A|=4), and (|C|=7), what is the value of \(|B\times C|\)?

Explanation opens after your attempt
Correct Answer

C. (42)

Step 1

Concept

Since \(|B|=\frac{24}{4}=6\), \(|B\times C|=6\cdot7=42\). First find the unknown cardinality.

Step 2

Why this answer is correct

The correct answer is C. (42). Since \(|B|=\frac{24}{4}=6\), \(|B\times C|=6\cdot7=42\). First find the unknown cardinality.

Step 3

Exam Tip

\(|B|=\frac{24}{4}=6\), इसलिए \(|B\times C|=6\cdot7=42\)। पहले अज्ञात समुच्चय की कार्डिनलिटी निकालें।
