यदि \(A\cap B=\varnothing\), तो (A-B) किसके बराबर होगा?
If \(A\cap B=\varnothing\), then (A-B) is equal to what?
Explanation opens after your attempt
A. (A)
Concept
When (A) and (B) have no common element, removing (B) from (A) leaves (A) unchanged. Therefore, (A-B=A).
Why this answer is correct
The correct answer is A. (A). When (A) and (B) have no common element, removing (B) from (A) leaves (A) unchanged. Therefore, (A-B=A).
Exam Tip
जब (A) और (B) में कोई साझा तत्व नहीं है, तो (B) को हटाने पर (A) वैसा ही रहता है। इसलिए (A-B=A) है।
