यदि (n\(A\times B\)=72) और (n(A)=8) है, तो (n(B)) कितना होगा?

If (n\(A\times B\)=72) and (n(A)=8), then what is (n(B))?

Explanation opens after your attempt
Correct Answer

A. (9)

Step 1

Concept

Since (n\(A\times B\)=n(A)n(B)), (72=8n(B)). In exams, apply the product rule first.

Step 2

Why this answer is correct

The correct answer is A. (9). Since (n\(A\times B\)=n(A)n(B)), (72=8n(B)). In exams, apply the product rule first.

Step 3

Exam Tip

क्योंकि (n\(A\times B\)=n(A)n(B)), इसलिए (72=8n(B))। परीक्षा में पहले गुणन नियम लगाएं।
