      Question

      Select the set in which the numbers are related in the same

      way as are the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - Operations 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) (72, 58, 86)(55, 42, 68)
      A (64, 50, 78) Correct Answer Incorrect Answer
      B (30, 26, 34) Correct Answer Incorrect Answer
      C (41, 73, 27) Correct Answer Incorrect Answer
      D (48, 32, 64) Correct Answer Incorrect Answer

      Solution

      The average of the 2nd and 3rd number equals the 1st number.

      (72, 58, 86) β†’ (58 + 86) / 2 = 72

      (55, 42, 68) β†’ (42 + 68)/2 = 55
      Now, checking the options:

      Option A β†’ (64, 50, 78) β†’ (50 + 78) / 2 = 64

      Option B β†’ (30, 26, 34) β†’ (26 + 34)/2 = 30

      Option C β†’ (41, 73, 27) β†’ (73 + 27)/2 = 50

      Option D β†’ (48, 32, 64) β†’ (32 + 64)/2 = 48
