      Question

      Four number-pairs have been given, out of which three

      are alike in some manner and one is different. Select the number-pair that is different.
      A 14: 75 Correct Answer Incorrect Answer
      B 18: 95 Correct Answer Incorrect Answer
      C 12: 65 Correct Answer Incorrect Answer
      D 21: 112 Correct Answer Incorrect Answer

      Solution

      The logic followed in the majority of the pairs is: (First Number Γ— 5) + 5 = Second Number. In 14: 75: 14 x 5 + 5 = 70 + 5 = 75 In 18: 95: 18 x 5 + 5 = 90 + 5 = 95 In 12: 65: 12 x 5 + 5 = 60 + 5 = 65 In 21: 112: 21 x 5 + 5 = 105 + 5 = 110 In the pair 21: 112, the result should be 110 to follow the pattern. Therefore, this pair is the odd one out. Hence, option d.
