यदि (n\(A\times B\)=8) और (n(B)=2) है, तो (n(A)) कितना होगा?
If (n\(A\times B\)=8) and (n(B)=2), what is (n(A))?
Explanation opens after your attempt
B. (4)
Concept
\(8=n(A)\times 2\), so (n(A)=4). For an unknown count, divide the total pairs by the known count.
Why this answer is correct
The correct answer is B. (4). \(8=n(A)\times 2\), so (n(A)=4). For an unknown count, divide the total pairs by the known count.
Exam Tip
\(8=n(A)\times 2\), इसलिए (n(A)=4)। अज्ञात संख्या के लिए कुल युग्मों को ज्ञात संख्या से भाग दें।
