    Question

    Select the option in which the numbers share 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 (12, 23, 90) Correct Answer Incorrect Answer
    B (15, 25, 80) Correct Answer Incorrect Answer
    C (20, 30, 100) Correct Answer Incorrect Answer
    D (22, 33, 110) Correct Answer Incorrect Answer

    Solution

    The logic followed here is: Third number = (First number + Second number) x 2 In (25, 35, 120), Third number = (25 + 35) x 2 = 60 x 2 = 120 In option 'A': (12, 23, 90), Third number = (12 + 23) x 2 = 35 x 2 = 70, which is not equal to 90. In option 'B': (15, 25, 80), Third number = (15 + 25) x 2 = 40 x 2 = 80, which matches. In option 'C': (20, 30, 100), Third number = (20 + 30) x 2 = 50 x 2 = 100, which matches. In option 'D': (22, 33, 110), Third number = (22 + 33) x 2 = 55 x 2 = 110, which matches.
