Both are the same.

When you hear the words iron and paper, some people might feel that iron seems heavier at first glance. The key is to realize that the weight of 10 tons doesn’t change, so they’re the same weight. Don’t overthink the question—just compare the weight simply.

Kyoto

In the middle of the word “東京都” (Tokyo Metropolis), there’s the kanji 京, right? If you start imagining buildings or land, you’ll end up wondering, “Where exactly is the center?” and won’t arrive at the correct answer. It’s a flash-of-insight quiz you can solve by noticing the hint hidden in the question itself.

dog

In English, “犬” is “dog,” and when you reverse “dog,” it becomes “good.” The key to solving the puzzle is noticing the hint from the phrase “when doing a handstand,” which suggests reversing the word. If you think of animal names and reverse them, you can arrive at the answer.

breath

When you go for a run for the first time in a while, you might find yourself out of breath. If you imagine someone actually running, you can picture the answer. When a problem statement contains a lot of information, a key to solving it is to infer which parts are necessary.

summer solstice

The day with the longest daytime and the day with the shortest nighttime actually mean the same thing. We tend to think of the opposite of the summer solstice as the winter solstice, but this is a unique question where the correct answer is hidden in the problem statement itself.

tofu

Because the word “fu” is written ten times, the ten “fu”s form the word tōfu (tofu). It’s a quiz where the continuous string of hiragana provides a hint through the number of characters to derive the answer.

three

There are three diamonds in total: one in the center of the card and one each at the top and bottom. It’s a trick question that makes you want to answer “two” if you only count the diamonds at the top and bottom of a playing card. If you’re given paper and a pen, it’s a good idea to actually draw a playing card.
