Question

Кузницу принесли 5 обрывок цепи по 3 звена в каждом и поручили соединить их в одну цепь из 15 звеньев.Кузнец выполнил заказ ,расковав и заковав 4 звена.Как он это сделал? Опиши его решение и сделай рисунок.

Answer 1

Берем один обрывок и раскрываем в нем все 3 кольца. Получается как бы 3 соединителя и 4 элемента (по 3 закрытых кольца в каждом). 4 соединяются 3-емя без особых правил.

Answer 2

Solution to Connecting the Chain

To connect the 5 chain fragments into one chain with 15 links, the blacksmith followed the following steps:

1. The blacksmith started with 5 chain fragments, each consisting of 3 links. This means there were a total of 5 * 3 = 15 links in the fragments.

2. The blacksmith then decided to remove 4 links from the chain. This left the blacksmith with 15 - 4 = 11 links.

3. The blacksmith then connected the remaining 11 links together to form a single chain with 11 links.

4. Since the original task was to create a chain with 15 links, the blacksmith still needed to add 15 - 11 = 4 more links to complete the chain.

5. To add the missing links, the blacksmith used additional chain links and connected them to the ends of the existing 11-link chain.

6. After adding the 4 missing links, the blacksmith successfully completed the task and created a chain with 15 links.

Here is a diagram illustrating the solution:

Fragment 1:  O---O---O
Fragment 2:  O---O---O
Fragment 3:  O---O---O
Fragment 4:  O---O---O
Fragment 5:  O---O---O

After removing 4 links:
Remaining Chain: O---O---O---O---O---O---O---O---O

Adding the missing links:
Final Chain:    O---O---O---O---O---O---O---O---O---O---O---O---O---O---O

In the diagram, each 'O' represents a chain link. The fragments are shown separately at the top, and the final chain with 15 links is shown at the bottom.

Please note that the diagram is a simplified representation and may not be to scale.

I hope this explanation and diagram help clarify how the blacksmith connected the chain fragments and completed the task. Let me know if you have any further questions!
