Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (23, 69, 105).
The logic used here is:
1st number × 3 = 2nd number
1st number × 5 = 3rd number
Option 1: (13, 39, 65)
13 × 3 = 39
13 × 5 = 65
This follows the logic.
Option 2: (23, 69, 105)
23 × 3 = 69
23 × 5 = 115
This does not follow the logic.
Hence, option 2 is the odd one out.
