100 marbles
Here’s a notoriously difficult question that was supposedly used in a Microsoft entry exam.
You have two boxes and a total of 50 red marbles and 50 blue marbles.
When distributing the marbles between the two boxes, what is the best way to maximize the probability of drawing a red marble? How would you approach this? The answer feels a bit counterintuitive, but if you’re not afraid of imbalance and make this choice, you’ll get better results.
I suspect this test is meant to see whether you can look at things from a perspective that overturns common sense.
If you can solve them all, you’re in the top 5%?! A test to challenge your brainpower
We can think of brain power not only as the knowledge we’ve acquired, but as a combination of various abilities such as judgment and analytical skills.
This content aims to check these different aspects of brain power through quizzes that test each ability.
The flow is to carefully read the questions, organize the information, look for hints, and think them through.
Flexibility in exploring different lines of thought may also be an important factor in reaching the answer.
An extremely difficult problem from a junior high school entrance exam
Here’s a problem: given a staircase with 8 steps, if you can climb either one step at a time or skip a step (climb two at a time), how many different ways are there to reach the top? This is a common and fairly challenging question in junior high entrance exams.
Listing all possibilities one by one is inefficient and error-prone.
A better approach is to start from smaller numbers of steps.
If there is only 1 step, there is 1 way to climb it; if there are 2 steps, there are 2 ways.
For 3 steps, you take the 2 ways from the 2-step case and add the options that start with a single step, giving 3 ways.
For 4 steps, you add the results for 3 steps and 2 steps, and so on.
Continuing this process up to 8 steps, the answer is 34 ways.
This sequence is known as the Fibonacci sequence.

Perfect score means you’re a genius! Dynamic visual acuity test
Dynamic visual acuity, which is also tested in senior courses during license renewal, is essential for driving.
Because you’re traveling at speed while driving, without dynamic visual acuity you can’t identify what’s passing by or approaching you.
It’s said that this dynamic visual acuity declines after age 60.
Here, Landolt rings and sequences of numbers used in vision tests will pass by at high speed, so please try selecting the correct answer from the four choices.

[Arithmetic Olympiad Super-Challenge] What is the perimeter of the rectangle?
![[Arithmetic Olympiad Super-Challenge] What is the perimeter of the rectangle?](https://i.ytimg.com/vi/AzAGNc7T9j4/sddefault.jpg)
At first glance, the perimeter here looks difficult to figure out, but since the light green shape inside is a square, you can easily find the answer by setting up an equation: let the side length of the square be ○, let the part obtained by subtracting the square’s side from 12 cm be □, and the part obtained by subtracting the square’s side from 9 cm be △.
For problems that seem hard, it’s a good idea to try replacing numbers with symbols and see if you can simplify your approach.
