Four number triads have been given, out of which three are alike in some manner and one is different. Select the number triad that is different
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (39, 48, 75).
The logic used here is:
First number + 19 = 2nd number
Second number + 17 = 3rd number
Option1: (46, 65, 82)
46 + 19 = 65
65 + 17 = 82
This follows the logic.
Option 2: (54, 73, 90)
54 + 19 = 73
73 + 17 = 90
This follows the logic.
Option 3: (21, 40, 57)
21 + 19 = 40
40 + 17 = 57
This follows the logic.
Option 4: (39, 48, 75)
39 + 19 = 58
58 + 17 = 75
This does not follow the logic.
Hence, option 4 is the odd one out.
