Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 191: 177.
The logic used here is:
1st number - 2nd number = 118
Option 1: 797: 679
797 - 679 = 118
This follows the logic.
Option 2: 373: 255
373 - 255 = 118
This follows the logic.
Option 3: 727: 609
727 - 609 = 118
This follows the logic.
Option 4: 191: 177
191 - 177 = 14
This does not follow the logic.
Hence, option 4 is the odd one out.
