    from the given alternatives.
    A 39 - 90 Correct Answer Incorrect Answer
    B 64 - 52 Correct Answer Incorrect Answer
    C 55 - 45 Correct Answer Incorrect Answer
    D 73 - 58 Correct Answer Incorrect Answer

    Solution

    The logic followed here is: The square of the 1st digit of the 1st number is added to the square of 2nd digit of the 1st number to get the 2nd number. In option 'A', 1st number = 39, 2nd number = (3² + 9²) = 90 In option 'B', 1st number = 64, 2nd number = (6² + 4²) = 52 In option 'C', 1st number = 55, 2nd number = (5² + 5²) = 50 ≠ 45 In option 'D', 1st number = 73, 2nd number = (7² + 3²) = 58
