Duck shooting in Buzzard Bay

Duck shooting in Buzzard Bay

The theme of this puzzle is familiar to the residents of the Buzzard Bay neighborhood, and presents one of the many problems that are undoubtedly known to all who enjoy the pleasures of duck hunting.

There are a thousand problems related to this sport, all of which are undoubtedly worthy of consideration, but it is possible that fans are more familiar with them than myself, so I will only refer to a single proposition that may be peculiarly characteristic of my style To hunt ducks

Of course, it is a great feat to give more than one duck with a single shot. As this is achieved only in the case that there are several ducks aligned, I began to study the principle by which the ducks are lined up in Buzzard Bay, and perhaps I have discovered something from my poor shooter skill.

I noticed that the birds invariably flew in two rows, with a guide duck, so to speak, on each side and in charge of each line, so that, as the illustration shows, one could imagine three lines of four.

Now, as soon as I could take aim on a line of four, I fired hoping to hit several of them with the same shot. I could kill one or even two, but my ambition to give four or nothing led me to the next and very interesting discovery. As soon as the smoke dissipated and I could open my eyes, I saw that the ten birds had changed direction to reorganize again in the swamp. What I particularly noticed, however, was that, although they always arrived, as I have shown, in lines of four, they invariably moved away in five lines of four.

How they made the change is something I could never notice, because of the smoke and the confusion, but I could see that the smallest possible number of ducks had changed position, so that it would give me special pleasure to give credit to any lucky person who achieves Correctly solve this problem.

The illustration shows ten ducks that advance in three rows of four. Rearrange them so that there are five rows of four, changing the position of the smallest possible number of ducks.

Incidentally, the change will also show how many ducks the hunter has achieved with his shot.

The problem can be solved by practically putting small chips on the ducks in the illustration and moving them to five rows of four.

Solution

Duck hunting in Buzzard Bay is solved by changing the position of two ducks, as shown in the illustration. This change forms 5 lines of 4 ducks in each and puts 1 duck in the hunter's bag.
