    Question

    Four number pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different.

    A (123, 234) Correct Answer Incorrect Answer
    B (345, 456) Correct Answer Incorrect Answer
    C (567, 729) Correct Answer Incorrect Answer
    D (678, 789) Correct Answer Incorrect Answer

    Solution

    The logic used here is: The difference between the second number and the first number in each pair should be 111. Option 1: (123, 234) →  234 - 123 = 111. This follows the logic. Option 2: (345, 456) → 456 - 345 = 111. This follows the logic. Option 3: (567, 729) → 729 - 567 = 162. This does not follow the logic. Option 4: (678, 789) → 789 - 678 = 111. This follow the logic. Hence, option 3 is the odd one out.
