64 : 6

36 : 5

169 : 11

196 : 12

- For each number-pair, the task is to determine if a consistent mathematical operation transforms the first number into the second.

- Option 1: 64 : 6

- Operation: 64 ? 8 (square root), then 8 - 2 = 6

- The operation is consistent here.

- Option 2: 36 : 5

- Operation: 36 ? 6 (square root), then 6 - 1 = 5

- This operation differs from the one used in the other pairs.

- Option 3: 169 : 11

- Operation: 169 ? 13 (square root), then 13 - 2 = 11

- The operation matches the one used in Option 1.

- Option 4: 196 : 12

- Operation: 196 ? 14 (square root), then 14 - 2 = 12

- The operation is consistent with Options 1 and 3.

Given these observations, the odd number-pair is Option 2: 36 : 5 because the operation subtracts 1 instead of 2 after finding the square root.

Option 2: 36 : 5 is the correct answer.
