यदि \(A\cap B=A\cap C\) और \(A'\cap B=A'\cap C\), तो (B) और (C) के बारे में सही निष्कर्ष क्या है?
If \(A\cap B=A\cap C\) and \(A'\cap B=A'\cap C\), what is the correct conclusion about (B) and (C)?

Correct Answer
A. (B=C)
Concept
(B=\(A\cap B\)\cup\(A'\cap B\)) and (C=\(A\cap C\)\cup\(A'\cap C\)), so (B=C). (A) and (A') partition (U).
Why this answer is correct
The correct answer is A. (B=C). (B=\(A\cap B\)\cup\(A'\cap B\)) and (C=\(A\cap C\)\cup\(A'\cap C\)), so (B=C). (A) and (A') partition (U).
Exam Tip
(B=\(A\cap B\)\cup\(A'\cap B\)) और (C=\(A\cap C\)\cup\(A'\cap C\)), इसलिए (B=C)। (A) और (A') पूरे (U) को बांटते हैं।
