यदि (A), (B), (C) ऐसे सेट हैं कि \(A\subseteq B\) और \(B\cap C=\varnothing\), तो \(A\cap C\) क्या होगा?
If sets (A), (B), (C) satisfy \(A\subseteq B\) and \(B\cap C=\varnothing\), what is \(A\cap C\)?
Explanation opens after your attempt
A. \(\varnothing\)
Concept
All elements of (A) are in (B), and (B) has no common element with (C). Therefore \(A\cap C=\varnothing\).
Why this answer is correct
The correct answer is A. \(\varnothing\). All elements of (A) are in (B), and (B) has no common element with (C). Therefore \(A\cap C=\varnothing\).
Exam Tip
(A) के सभी तत्व (B) में हैं और (B) का (C) से कोई सामान्य तत्व नहीं है। इसलिए \(A\cap C=\varnothing\) है।
