[Arithmetic Quiz] 2018 Entrance Exam Problem from Joshi Gakuin Junior High School
![[Arithmetic Quiz] 2018 Entrance Exam Problem from Joshi Gakuin Junior High School](https://i.ytimg.com/vi/Ke76I6r8hzY/sddefault.jpg)
It seems this is an exam question from a famous girls’ junior high school.
Apparently, getting into a prestigious school requires a great deal of effort.
If an elementary school girl could breeze through questions like these, we adults would lose our persuasive authority.
It appears to be from a 2018 exam.
If you can solve this, you might be smarter than an excellent elementary school student.
Matchstick puzzle: Move 3 sticks to make 3 squares.
See the answer
Move the two vertical matchsticks at the top to the left and right, and move the horizontal matchstick in the top center downward.
Since you only need to make three squares, it seems like there could be infinitely many answers, but if you want a neat arrangement with no surplus or shortage, there’s only one solution. Because there are no constraints regarding the leftover matchsticks, that might be the tricky part of this problem. Please try it with the mindset of “Let’s make exactly three squares with no more and no less!”
30 trick riddles that 80% of people can’t solve
Let’s play with words! Here are 30 ideas for trick riddles that 80% of people can’t solve.
Trick riddles can leave you feeling stumped, but seeing the answer often makes you think, “Ah, I get it now!” or “So that’s how it works!” This time, let’s take on riddles said to be unsolvable for 80% of people.
For example, one question goes: “One day, a precious musical instrument broke and could no longer be used.
What instrument was it?”
Matchstick puzzle: Move one stick to make it half.
See the answer
If you move the bottom matchstick of the 0 to below the space between the 1 and 0 and change its orientation, it becomes a “5.”
Because it’s half of ten, I can at least think to somehow make the shape of a “5,” but how should I move it? There’s no restriction saying “you mustn’t change the orientation,” so the shift in thinking to “let’s try changing the orientation!” is the key to solving the problem. Still, it’s a really well-crafted puzzle. I’d love to pose it to friends in my class who enjoy quizzes.
[Math Quiz] What number goes in the blank?
![[Math Quiz] What number goes in the blank?](https://i.ytimg.com/vi/KMFEt9vECOM/sddefault.jpg)
Do you know the Arithmetic (Math) Olympiad, where people around the world compete in their mathematical abilities? Here’s a fill-in-the-blank problem from the 2019 trial that lets you experience its atmosphere.
You’re given a grid with 4 rows and 7 columns.
It contains the numbers 1 through 5, but three cells near the center are blank—try filling them in.
What makes this problem interesting is that it doesn’t rely on adding or dividing numbers; it calls for a flash of insight.
Use symbols to make four numbers equal 10.
Insert one of the symbols +, −, ×, or ÷ between four randomly arranged numbers to make the final result 10—this makes a perfect brain-training activity! If you use parentheses, you can freely change the order of operations, so children who have learned parentheses should actively incorporate them.
Also remember that multiplication and division are performed before addition and subtraction, so keep that in mind as you complete your expressions.
Once you get used to it, it might be fun for parents and friends to take turns making problems for each other!
Matchstick puzzle: Using 12 matches, create six enclosures of equal size.
See the answer
Make it a regular hexagon
Imagine pens that hold one animal each, and think about building them with 12 matchsticks. We tend to try making them as squares, but let’s shift that thinking. A triangular pen only needs three matchsticks, so… with a clever combination, you can form a regular hexagon. It’s a surprisingly tricky puzzle!
An IQ 100-level question that 84% of elementary school students and 78% of adults solved
I don’t think most people ever get the chance to actually measure their IQ score.
For those people, how about this video? If you can solve the problem in it, they say your IQ is over 100.
And guess what—I solved it! So it seems my IQ is over 100 (lol).
It made me a little happy, and I recommend you and your child give it a try too.
Junior high school entrance exam geometry problems
Since it’s a geometry problem from a junior high school entrance exam, it’s genuinely difficult.
I think children who overcome such hurdles and pass are truly admirable.
I’m also curious about what kind of adults those who solved problems like this and got accepted will become in the future.
There were no children around me who took such competitive junior high school exams (lol).
I feel like I could never compete with kids who are so good at solving problems like these.
Only 3% of adults get it right! A 4th grade elementary school math problem

When you’re suddenly given just this information—“A pencil and a notebook together cost 100 yen, and the pencil is 40 yen cheaper than the notebook”—it’s not uncommon to panic and answer that the pencil costs 60 yen.
But that’s incorrect.
Saying “40 yen cheaper” doesn’t mean the notebook costs 40 yen.
You need to find prices where the difference between the pencil and the notebook is 40 yen.
With problems that have a bit of a trick like this, it’s important not to blurt out an answer right away, but to pause for a moment.
Try shifting your way of thinking, and you’ll start to see the numbers differently.
