    Question

    Find the odd one out.

    A.

    75

    B.

    115

    C.

    207

    D.

    299

    Correct option is A

    Given:
    Numbers: 75, 115, 207 and 299
    Concept:
    Observe the common mathematical property among the given numbers and identify the one that does not follow it.
    Solution:
    115 = 5 × 23
    207 = 9 × 23
    299 = 13 × 23
    All three numbers are multiples of 23.
    75 is not a multiple of 23.
    Hence, 75 is the odd one out.
    Final Answer: 75
