    Question

    In a certain code language, ‘618293’ is written as ‘517489. How will ‘437251’ be written as in that language?

    A.

    398461

    B.

    369441

    C.

    396441

    D.

    396431

    Correct option is C

    Logic:
    First position: subtract 1 from the digit.
    Second position: square the digit.
    This alternates for the rest of the digits.
    Let’s analyze the example provided:
    618293 is written as 517489.
    1st position: 6 → 6 - 1 = 5
    2nd position: 1 → 1² = 1
    3rd position: 8 → 8 - 1 = 7
    4th position: 2 → 2² = 4
    5th position: 9 → 9 - 1 = 8
    6th position: 3 → 3² = 9
    Now, let's apply the same logic to 437251:
    1st position: 4 → 4 - 1 = 3
    2nd position: 3 → 3² = 9
    3rd position: 7 → 7 - 1 = 6
    4th position: 2 → 2² = 4
    5th position: 5 → 5 - 1 = 4
    6th position: 1 → 1² = 1
    Thus, 437251 will be written as 396441.
    Correct answer is (c) 396441.
