    Question

    Select the set in which the numbers are related in the

    same way as are the numbers of the following sets: (12, 18, 45) (14, 22, 54)
    A (16, 24, 60) Correct Answer Incorrect Answer
    B (20, 30, 80) Correct Answer Incorrect Answer
    C (10, 16, 42) Correct Answer Incorrect Answer
    D (18, 28, 65) Correct Answer Incorrect Answer

    Solution

    The relationship followed in these sets is: Add the first and second numbers, then multiply the sum by 1.5 to get the third number. Alternatively, the logic can be seen as: 3rd number = 1.5 x (1st + 2nd) (12, 18, 45) → 1.5 x (12 + 18) = 1.5 x 30 = 45 (14, 22, 54) → 1.5 x (14 + 22) = 1.5 x 36 = 54 (16, 24, 60) → 1.5 x (16 + 24) = 1.5 x 40 = 60 (20, 30, 80) → 1.5 x (20 + 30) = 1.5 x 50 = 75 (10, 16, 42) → 1.5 x (10 + 16) = 1.5 x 26 = 39 (18, 28, 65) → 1.5 x (18 + 28) = 1.5 x 46 = 69
