      Question

      Select the set in which the numbers are related in the

      same way as are the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - operation on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed) (15, 100, 25)
      A (12, 49, 19) Correct Answer Incorrect Answer
      B (28, 49, 35) Correct Answer Incorrect Answer
      C (19, 81, 28) Correct Answer Incorrect Answer
      D (10, 30, 15) Correct Answer Incorrect Answer

      Solution

      The logic followed here is as follows (3rd number - 1st number)² = 2nd number (15, 100, 25) → (25 – 15)² = 10² = 100. (12, 49, 19) → (19 – 12)² = 7² = 49. (28, 49, 35) → (35 – 28)² = 7² = 49. (19, 81, 28) → (28 – 19)² = 9² = 81. (10, 30, 15) → (15 – 10)² = 5² = 25.
