Question

    Select the option in which the numbers are related in

    the same way as are the numbers of the following set. (11, 31, 800)
    A (12, 29, 612) Correct Answer Incorrect Answer
    B (14, 38, 1152) Correct Answer Incorrect Answer
    C (16, 30, 400) Correct Answer Incorrect Answer
    D (19, 42, 1000) Correct Answer Incorrect Answer

    Solution

    The logic followed here is as follows: The third number is obtained by squaring the difference between the first two numbers and then multiplying the result by 2. Third number = (Second number - First number)² x 2 For the given set (11, 31, 800) → (31 - 11)² x 2 = 20² x 2 = 400 x 2 = 800. A (12, 29, 612) → (29 - 12)² x 2 = 17² x 2 = 289 x 2 = 578. B (14, 38, 1152) → (38 - 14)² x 2 = 24² x 2 = 576 x 2 = 1152. C (16, 30, 400) → (30 - 16)² x 2 = 14² x 2 = 196 x 2 = 392. D (19, 42, 1000) → (42 - 19)² x 2 = 23² x 2 = 529 x 2 = 1058.
