      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) (91, 78, 104)(68, 55, 81)
      A (88, 72, 98) Correct Answer Incorrect Answer
      B (45, 30, 60) Correct Answer Incorrect Answer
      C (58, 41, 73) Correct Answer Incorrect Answer
      D (78, 64, 90) Correct Answer Incorrect Answer

      Solution

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

      (91, 78, 104) β†’ (78 + 104) / 2 = 91

      (68, 55, 81) β†’ (55 + 81)/2 = 68

      Now, checking the options:

      Option A β†’ (88, 72, 98) β†’ (72 + 98) / 2 = 85

      Option B β†’ (45, 30, 60) β†’ (30 + 60)/2 = 45

      Option C β†’ (58, 41, 73) β†’ (41 + 73)/2 = 57

      Option D β†’ (78, 64, 90) β†’ (64 + 90)/2 = 77
