    Note: The correction was made for Q11(M1), Q11(M2), Q15(M3), and Q14(M4).
    The correct answer is 26, replacing the earlier erroneous value 61.

    Explanations and Clarifications

    • A total of 2,736 challenges were received (some possibly duplicates).

    • Of these, 170 challenges pertained to questions Q11 (M1), Q11 (M2), Q15 (M3), and Q14 (M4).

      • The provisional key listed the answer as 61, but this was found incorrect.

      • The correct answer is 26, hence this challenge has been accepted, and the answer updated.

    • Another 430 challenges were for Q23 (M1), Q24 (M2), Q21 (M3), Q22 (M4).

      • These were rejected as the reasoning used by challengers did not meet the required problem constraints or mathematical logic.

    • A few students pointed out a notation error in the question (appearance of poly(√A,B) instead of poly(A,B)).

      • The issue was purely typographical and did not impact the question’s logic.

    • No other challenges were found significant for revision.

      • Queries about “quality of print” or similar have not been considered academic in nature.

    Official Statement

    The Mathematics Teachers’ Association (India) noted that the evaluation process followed a thorough verification system. Only mathematically justified objections were accepted. The final key now stands as official and binding for result calculation.

    Next Steps

    Candidates can now estimate their probable scores using the final key. The IOQM 2025 results and qualification list for INMO 2026 are expected to be declared soon on the official website.
