यदि \(A=\{2,4,6,8\}\) और \(B=\{1,2,8,9\}\), तो केवल (A) वाला भाग क्या है?
If \(A=\{2,4,6,8\}\) and \(B=\{1,2,8,9\}\), what is the only (A) part?
Explanation opens after your attempt
A. ({4,6})
Concept
For only (A), find (A-B). Since (2) and (8) are common, ({4,6}) remains.
Why this answer is correct
The correct answer is A. ({4,6}). For only (A), find (A-B). Since (2) and (8) are common, ({4,6}) remains.
Exam Tip
केवल (A) के लिए (A-B) निकालते हैं। (2) और (8) साझा हैं, इसलिए ({4,6}) बचता है।
