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)

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
