Question

    In the following question, select the odd pair of

    numbers from the given alternatives.
    A 13 – 179 Correct Answer Incorrect Answer
    B 25 : 635 Correct Answer Incorrect Answer
    C 19 : 371 Correct Answer Incorrect Answer
    D 27 : 749 Correct Answer Incorrect Answer

    Solution

    The pattern followed here is: (1st term)²  + 10 = 2nd term 13 – 179 → (13)²  + 10 = 169 + 10 = 179 25 – 635 → (25)²  + 10 = 625 + 10 = 635 19 – 371 → (19)²  + 10 = 361 + 10 = 371 27 – 749 → (27)²  + 10 = 729 + 10 = 739 ≠ 749   Hence, '27 : 749' is the odd pair. Option (D) is the correct answer.
