Correct Answer

A. इनसे (n\(A\cup B\cup C\)) निश्चित हो जाता हैThese determine (n\(A\cup B\cup C\))

Step 1

Concept

A few difference regions alone do not determine the whole union because many common regions remain unknown. First check whether the data is sufficient.

Step 2

Why this answer is correct

The correct answer is A. इनसे (n\(A\cup B\cup C\)) निश्चित हो जाता है / These determine (n\(A\cup B\cup C\)). A few difference regions alone do not determine the whole union because many common regions remain unknown. First check whether the data is sufficient.

Step 3

Exam Tip

केवल कुछ अंतर क्षेत्रों से पूरा संघ निश्चित नहीं होता क्योंकि कई साझा भाग अज्ञात रहते हैं। डेटा पर्याप्त है या नहीं, पहले जांचें।

Correct Answer

A. इनसे (n\(A\cup B\cup C\)) निश्चित हो जाता हैThese determine (n\(A\cup B\cup C\))

Step 1

Concept

A few differences alone do not determine the whole union because intersection information is incomplete. In such questions, check whether the data is sufficient.

Step 2

Why this answer is correct

The correct answer is A. इनसे (n\(A\cup B\cup C\)) निश्चित हो जाता है / These determine (n\(A\cup B\cup C\)). A few differences alone do not determine the whole union because intersection information is incomplete. In such questions, check whether the data is sufficient.

Step 3

Exam Tip

केवल कुछ अंतरों से पूरा संघ निश्चित नहीं होता क्योंकि प्रतिच्छेदों की जानकारी अधूरी है। ऐसे प्रश्नों में पर्याप्त डेटा की जांच करें।
