    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) → (58 + 86) / 2 = 72

    (55, 42, 68) → (42 + 68)/2 = 55
    Now, checking the options:

    Option A → (64, 50, 78) → (50 + 78) / 2 = 64

    Option B → (30, 26, 34) → (26 + 34)/2 = 30

    Option C → (41, 73, 27) → (73 + 27)/2 = 50

    Option D → (48, 32, 64) → (32 + 64)/2 = 48
