यदि \(A\subseteq B\), तो (\(A\cup B\)-A) किसके बराबर होगा?
If \(A\subseteq B\), then (\(A\cup B\)-A) is equal to what?
Explanation opens after your attempt
A. (B-A)
Concept
Since \(A\subseteq B\), \(A\cup B=B\), and (\(A\cup B\)-A=B-A). In subset problems, simplify the union first.
Why this answer is correct
The correct answer is A. (B-A). Since \(A\subseteq B\), \(A\cup B=B\), and (\(A\cup B\)-A=B-A). In subset problems, simplify the union first.
Exam Tip
क्योंकि \(A\subseteq B\), इसलिए \(A\cup B=B\), और (\(A\cup B\)-A=B-A) है। उपसमुच्चय में पहले संघ को सरल करें।
