यदि (A\setminus\(B\setminus C\)) को सरल किया जाए, तो सही रूप कौन-सा है?

If (A\setminus\(B\setminus C\)) is simplified, which form is correct?

Explanation opens after your attempt
Correct Answer

A. (\(A\setminus B\)\cup\(A\cap C\))

Step 1

Concept

Removing \(B\setminus C\) means removing elements in (B) and outside (C), so elements of (A) remain if they are outside (B) or in (C). Verify identities by element method.

Step 2

Why this answer is correct

The correct answer is A. (\(A\setminus B\)\cup\(A\cap C\)). Removing \(B\setminus C\) means removing elements in (B) and outside (C), so elements of (A) remain if they are outside (B) or in (C). Verify identities by element method.

Step 3

Exam Tip

\(B\setminus C\) से हटाने का अर्थ है (B) में और (C) से बाहर तत्व हटाना, इसलिए (A) में या तो (B) से बाहर या (C) में मौजूद तत्व बचते हैं। पहचान को तत्व विधि से जांचें।
