Try this for size (each fruit represents a positive integer):

The actual answer being (only the smallest triplet:)

I love this.

 

 

All I knew was that I did not know enough to be able to solve it

This isn't really a brain-teaser like the other two puzzles, it's just a really hard math problem. Since probably more than half of the general population can't even solve high school algebra problems, it's hardly surprising that this would stump 95% of people (I suspect it's actually more than 99%).

That's the joke barmar. :lol:

[gwnn]

The whole reddit thread is hilarious (for very particular values of "hilarious").

 

 

This one apparently is legit 100% unsolved.

[kuhchung]

5% of people solved this!?

 

edit: oh it's a joke lol
