Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 68: 196.
The logic used here is:
1st number × 3 - 10 = 2nd number
Option 1: 54: 152
54 × 3 - 10 = 152
This follows the logic.
Option 2: 82: 236
82 × 3 - 10 = 236
This follows the logic.
Option 3: 36: 98
36 × 3 - 10 = 98
This follows the logic.
Option 4: 68: 196
68 × 3 - 10 = 194
This does not follow the logic.
Hence, option 4 is the odd one out.
