[Brain Training] Difficult Riddles That Even Adults Struggle With (41–50)
Even though it was taken, everyone’s laughing. I wonder why.
I ended up fighting after my friend and I both tried to take it… It’s something every elementary schooler has probably experienced at least once.
Having something taken from you feels awful and makes you sad, right? So let’s try this puzzle.
Why is everyone smiling even though something was ‘taken’? The first thing to think about when solving this is the meaning of the word ‘taken’ (torareta).
It’s deliberately written in hiragana, so try converting it to kanji and imagining what situation it might describe.
The answer is: because it was a photograph.

It seems like a question that would trip up adults more than children.
When you read the problem statement, you instinctively want to treat it like an arithmetic problem and think, “5 – 1 = 4, so the answer is 4!” But remember, it’s a trick question.
The hint to solving it is that the candy wasn’t given to someone else, nor did it disappear.
If you think about how many candies you have after you lick one, you should arrive at the correct answer.
An elementary school student with a flexible mind might solve it right away!

I don’t know when this phrase started becoming popular, but more and more people have begun saying the slightly excuse-like, “Ah, so that’s what you meant.” Well, their frustrated reaction is amusing, so it doesn’t really bother me, but where did the phrase originally come from? If you know, please tell me! There are people who ask trick questions designed to annoy you—questions that make you want to say, “Ah, so that’s what you meant.” Maybe that kind of back-and-forth—like the classic “If you say this, I’ll say that”—can be fun if it’s between people who are really close.
The key to enjoying it is not to get worked up!

Are you bad at trick questions? I couldn’t even get the classic one—“Which is heavier, 1 kg of iron or 1 kg of cotton?”—I just kept groaning and never reached the right answer.
I’m the type who overthinks and self-destructs, assuming there must be some hidden twist just because it’s presented as a question.
I can’t handle normal trick questions, so if they’re labeled “super hard,” then… As for those tougher trick questions, the rising YouTuber Chonmage Kozou—who suddenly appeared with the greeting “Hikiniku desu!”—is enjoying them too.
