    Question

    Select the set in which the numbers are not related in

    the same way as the numbers of the following sets. (24, 47, 71) (18, 35, 53)
    A (20, 39, 59) Correct Answer Incorrect Answer
    B (34, 67, 101) Correct Answer Incorrect Answer
    C (15, 47, 55) Correct Answer Incorrect Answer
    D (28, 55, 83) Correct Answer Incorrect Answer

    Solution

    The logic followed here is: 2nd number = 1st number X 2 – 1; 3rd number = 1st number + 2nd number. In (24, 47, 71) → 24 X 2 - 1 = 48 - 1 = 47, 24 + 47 = 71. In (18, 35, 53) →18 X 2 - 1 = 36 - 1 = 35, 18 + 35 = 53 In option 'A', (20, 39, 59) → 20 X 2 - 1 = 40 - 1 = 39, 20 + 39 = 59 In option 'B', (34, 67, 101) → 34 X 2 - 1 = 68 - 1 = 67, 34 + 67 = 101 In option 'C', (15, 47, 55) → 15 X 2 - 1 = 30 - 1 = 29 ≠ 47, 15 + 29 = 44 ≠ 55 In option 'D', (28, 55, 83) → 28 X 2 - 1 = 56 - 1 = 55, 28 + 55 = 83
