    in a certain way and thus form a group. Which is the one that does not belong to that group?
    A 364 Correct Answer Incorrect Answer
    B 142 Correct Answer Incorrect Answer
    C 586 Correct Answer Incorrect Answer
    D 476 Correct Answer Incorrect Answer

    Solution

    The logic here is: (1st digit + 3) = 2nd digit; (2nd digit – 2) = 3rd digit   364 à (3 + 3) = 6; (6 – 2) = 4 142 à (1 + 3) = 4; (4 – 2) = 2 586 à (5 + 3) = 8; (8 – 2) = 6 476 à (4 + 3) = 7; (7 – 2) = 5 ≠ 6   Thus, the odd one out is 476. Hence, the correct answer is (D).
