Duck: 1 kg
Putting all three on the scale gives:
98 + 4 + 1 = 103 kg
Not 99.
The puzzle secretly mixes pure math operations with real-world measurement, which breaks the rules of logic. Division and subtraction exist on paper — a scale can only add.
And that’s why this “clever” animal equation goes viral: it looks smart, but collapses the moment you apply real-world reasoning.
Moral of the story?
If the logic feels confusing, it probably is.
