यदि \(A=\{1,2,3\}\) और \(B=\{1,2,3,{1}\}\) हैं तो (A) और (B) का संबंध क्या है?
If \(A=\{1,2,3\}\) and \(B=\{1,2,3,{1}\}\), what is the relation between (A) and (B)?
Explanation opens after your attempt
Correct Answer
B. \(A\subset B\) और \(A\ne B\)\(A\subset B\) and \(A\ne B\)
Concept
All elements of (A) are in (B), and (B) has the extra element ({1}). Treat ({1}) as different from (1).
Why this answer is correct
The correct answer is B. \(A\subset B\) और \(A\ne B\) / \(A\subset B\) and \(A\ne B\). All elements of (A) are in (B), and (B) has the extra element ({1}). Treat ({1}) as different from (1).
Exam Tip
(A) के सभी अवयव (B) में हैं और (B) में अतिरिक्त अवयव ({1}) है। ({1}) को (1) से अलग मानें।
