      Question

      Four number-pairs are given, out of which three are

      alike in certain manner and one is different. Choose the different number-pair.
      A 10:100 Correct Answer Incorrect Answer
      B 25:200 Correct Answer Incorrect Answer
      C 18:144 Correct Answer Incorrect Answer
      D 22:165 Correct Answer Incorrect Answer

      Solution

      The second number is divisible by the first: (100 ÷ 10) = 10 (200 ÷ 25) = 8 (144 ÷ 18) = 8 (165 ÷ 22) leaves a remainder of 11. Option (d) is the odd one out.
