    Question

    Three of the following four number-clusters are alike in a certain way and thus form a group. Which is the one that does not belong to that group?

    A 246 Correct Answer Incorrect Answer
    B 124 Correct Answer Incorrect Answer
    C 369 Correct Answer Incorrect Answer
    D 246 Correct Answer Incorrect Answer

    Solution

    The logic here is: (1st digit) x 2 = 2nd digit; (2nd digit + 2) = 3rd digit   246 → 2 x 2 = 4; 4 + 2 = 6 124 → 1 x 2 = 2; 2 + 2 = 4 369 → 3 x 2 = 6; 6 + 2 = 8 ≠ 9 246 → 2 x 2 = 4; 4 + 2 = 6 Thus, the odd one out is 369. Hence, the correct answer is (C).
