I came across a viral brain test where given the below image it was asked to solve the puzzle. Most of the online communities are explaining that the answer will be 3. For example https://www.youtube.com/watch?v=Iqa3gSDpSqo.
But to me its like impossible to solve. Because there are not enough information on how equations are constructed. For example some people might count the number of white points in the ball and result a different answer.
Is there anything I am missing?
Mathematically, the question doesn't make sense. We can figure out that a clock at 3 is worth 3, and that a four-bladed fan is worth 4 (or possibly -3), but we have no information on what the clock at 2 or a three-bladed fan is worth.
If you want to go from mathematics to puzzles, then 3 is the most likely answer, but you can probably twist it to anything you'd like if you just try hard enough.
