यदि (n(A)=6) और (n\(A\times B\)=48) है, तो (n(B)) कितना होगा?

If (n(A)=6) and (n\(A\times B\)=48), what is (n(B))?

Explanation opens after your attempt
Correct Answer

C. (8)

Step 1

Concept

(n\(A\times B\)=n(A)n(B)), so (48=6n(B)) and (n(B)=8). Use the formula in reverse in such questions.

Step 2

Why this answer is correct

The correct answer is C. (8). (n\(A\times B\)=n(A)n(B)), so (48=6n(B)) and (n(B)=8). Use the formula in reverse in such questions.

Step 3

Exam Tip

(n\(A\times B\)=n(A)n(B)), इसलिए (48=6n(B)) और (n(B)=8)। ऐसे प्रश्नों में सूत्र को उल्टा लगाएं।
