182 : 12

461 : 20

239 : 14

305 : 16

Let’s crack these number-pairs and see which one doesn’t fit:

- Option 1: 182 : 12

If you add the digits of 182 (1 + 8 + 2), you get 11. Nothing matches 12.

If you subtract 1 from 182 (182 - 170), nope, not matching. Try dividing, factors—still no clear link.

- Option 2: 461 : 20

Add digits: 4 + 6 + 1 = 11. Nope.

461 divided by 20 is not an integer.

But 4 × 6 × 1 = 24. Still not matching, but let’s keep going.

- Option 3: 239 : 14

2 + 3 + 9 = 14. Well, there it is.

- Option 4: 305 : 16

3 + 0 + 5 = 8. Nope.

But wait—not matching the pattern from Option 3. Could division work? 305 ÷ 16… not an integer.

But here’s the thing:

Look closely at option 3. It fits—add the digits, you get the second number. Now check the rest: none of them do.

- So the odd one out is actually 182 : 12—it doesn't fit the “sum of digits equals second number” pattern.

Correct Answer: Option 1 (182 : 12)
