    the same relationship in set as that shared by the numbers in the given set. (Note: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 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) (25, 35, 120)
    A (15, 25, 80) Correct Answer Incorrect Answer
    B (12, 18, 60) Correct Answer Incorrect Answer
    C (20, 30, 100) Correct Answer Incorrect Answer
    D (22, 33, 90) Correct Answer Incorrect Answer

    Solution

    The logic is: Third number = (First number + Second number) x 2 In (25, 35, 120), Third number = (25 + 35) x 2 = 60 x 2 = 120. A) (15 + 25) x 2 = 40 x 2 = 80, matches. B) (12 + 18) x 2 = 30 x 2 = 60, matches. C) (20 + 30) x 2 = 50 x 2 = 100, matches. D) (22 + 33) x 2 = 55 x 2 = 110 which is not equal to 90.
