The logic used here is: 47 : 58 : 71 47 + (4 + 7) = 47 + 11 = 58 58 + (5 + 8) = 58 + 13 = 71 Similarly, we would check for all the options: Option 1 : 68 : 80 : 88 68 + (6 + 8) = 68 + 14 = 82 Option 1 does not follow the same pattern. Option 2: 72 : 81 : 90 72 + (7 + 2) = 72 + 9 = 81 81 + (8 + 1) = 81 + 9 = 90 It follows the pattern. So we will not check the further options. Hence, 72 : 81 : 90 is the correct answer. |
