एका सांकेतिक भाषेत 725 साठी *@# हा संकेत आहे. 534 साठी $©* हा संकेत आहे. 231 साठी ©@ हा संकेत आहे. तर 375 या अंकासाठी कोणता संकेत असेल ?

This question was cancelled (#) in the official MPSC final answer key.

Key Points:
• Given sets:
• '725' corresponds to symbols {*, @, #}
• '534' corresponds to symbols {, ©, *}
• '231' corresponds to symbols {©, @} (Note: Only 2 symbols printed for a 3-digit number in the original question booklet: 't©@' / '©@', causing an unambiguous mapping discrepancy).
• Common element between 725 and 534 is '5', and the common symbol is '*', so 5 = *.
• Common digit between 725 and 231 is '2', and common symbol is '@', so 2 = @.
• Hence, for 725, remaining digit 7 = #.
• For 375, the symbols must contain the codes for 3, 7 (#), and 5 (*). However, the code for digit 3 cannot be consistently uniquely derived due to printing discrepancy in the third code.
• Because of printing errors and symbol ambiguities in the question paper, MPSC officially cancelled this question.
• Key Takeaway: Always map common elements across sets to isolate individual codes; printing discrepancies lead to question cancellation.
