R = वास्तव संख्यांचा संच, I = पूर्णांक संख्यांचा संच, W = पूर्ण संख्यांचा संच, N = नैसर्गिक संख्यांचा संच आहेत, तर खालील विधानांमधून चूकीचे विधान शोधा.

The correct answer is Option A (I ⊂ W ⊂ N).

Key Points:
• Question Cancelled in Official Answer Key:
• In the official MPSC final answer key, Question 11 is marked with '#' (cancelled/deleted).
• Mathematical Reason for Ambiguity:
• Natural numbers N = 1, 2, 3, ...
• Whole numbers W = 0, 1, 2, 3, ...
• Integers I = ..., -2, -1, 0, 1, 2, ...
• Real numbers R
• The correct subset relation is N ⊂ W ⊂ I ⊂ R.
• Statement (1): I ⊂ W ⊂ N is completely WRONG (integers are not a subset of natural numbers).
• Statement (4): W ∩ N = N = 1, 2, 3, ..., NOT 0 (the intersection is N, while the difference W setminus N = 0). Thus, Statement (4) is ALSO mathematically WRONG.
• Because both Statement (1) and Statement (4) are incorrect statements, multiple options qualified as the correct choice for 'find the wrong statement'. Therefore, MPSC rightly cancelled the question.
• Key Takeaway: The hierarchy of numbers is N ⊂ W ⊂ I ⊂ Q ⊂ R; both options 1 and 4 contained false assertions, leading to cancellation.
