Are you ready for a lazy Sunday? Then it can’t hurt to put your mind to the test with a relaxing puzzle. This week, you can try to decode the path to glory with a healthy dose of common sense.
In July, the International Congress of Mathematicians was held in Saint Petersburg. During this four-year event, lectures are given by the brightest math geniuses, but most importantly: the Fields Medal is also awarded. Only mathematicians under the age of 40 have a chance of winning the most important prize in their field.
In the lead-up to the so-called “Nobel Prize in Mathematics”, the organizers launched a competition in mathematics for the general public. This question, centered around logic, is part of this test. good luck!
Vera must walk through the 3×3 grid (bottom left). She can only move horizontally or vertically, passing each square only once. Bottom right you see a possible path. When Vera wrote the result of her trip, she got the number 84937561. What is the largest possible number that Vera could make up during her journey through the net? Scroll down for the correct answer.
Correct answer: 573618492
First of all: the number should, of course, consist of nine digits and start with the highest number possible. Suppose we color the square like a chessboard, the color of the square should change every time.
Since there are five white squares and four dark squares, Vera’s career must begin on a white square. The largest number in a white box is 5.
The highest possible number for each step must then be chosen. This way you go through 7 and 3. Then 9 should follow, but from this position the path cannot continue correctly. After all, this creates two areas of the square that cannot be connected to each other.
Because of this principle you can’t go from 3 to 8. So it should be 6. From this point on, the rest is illustrative. So the end result is 573618492.
