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 (85, 72, 98) Correct Answer Incorrect Answer
    B (44, 30, 60) Correct Answer Incorrect Answer
    C (57, 41, 73) Correct Answer Incorrect Answer
    D (77, 64, 90) Correct Answer Incorrect Answer

    Solution

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

    (91, 78, 104) → (78 + 104) / 2 = 91

    (68, 55, 81) → (55 + 81)/2 = 68

    Now, checking the options:

    Option A → (85, 72, 98) → (72 + 98) / 2 = 85

    Option B → (44, 30, 60) → (30 + 60)/2 = 45

    Option C → (57, 41, 73) → (41 + 73)/2 = 57

    Option D → (77, 64, 90) → (64 + 90)/2 = 77
