Solution of L’Enigma with blue eyes
Solution
Milena has 3 children: two 2 years old and one 9 years old.
Let’s start by producing all the combinations of three numbers that, multiplied with each other, give as product 36:
1/1/36 Sum 38
1/2/18 Sum 21
1/3/12 Sum 16
1/4/9 Sum 14
1/6/6 Sum 13
2/2/9 Sum 13
2/3/6 Sum 11
3/3/4 Sum 10
Attention now! Emma knows the house number and then the sum of ages! So if he deto that the data were insufficient it means that the door number corresponded to the only two triplets that have the same sum: 1/6/6 and 2/2/9. At this point is therefore illuminating the last clue that is not only the color of the eyes but is the definite article! Milena in fact says that “the oldest son has blue eyes” that is, he has only one older son. The age of the children is 9 years, 2 years and 2 years.

A logical-mathematical puzzle
is a problem that challenges your thinking. It combines logic and mathematics to test problem-solving skills. These puzzles require you to find patterns, make deductions, and apply mathematical concepts to find a solution.
They come in many forms. Some involve simple arithmetic, while others may need more complex reasoning. For example, a classic puzzle could ask you to solve an equation or find the next number in a sequence. Others might involve shapes or objects, where you must identify a hidden rule.
These puzzles are often based on principles like logic, probability, or combinatorics. They help you think critically and improve your ability to recognize patterns. Solving them requires patience and creativity, as the solution is often not immediately obvious.
Logical-mathematical puzzles also come in different levels of difficulty. Some can be solved in minutes, while others may take hours or even days. The satisfaction of finding the solution makes these puzzles fun and rewarding.
They are not just for fun. Solving them can enhance your cognitive abilities. They improve skills like deductive reasoning, pattern recognition, and strategic thinking, all of which are valuable in everyday life and work.
