King’s Horses
A king has 32 horses. He has arranged them in a square, as shown in the figure given
below, such that he can see 12 horses along each line of sight, as indicated in the
picture.
The king has instructed the watchman to make sure there are 32 horses all the time,
no more, no less. Every circle must have at least one horse. The watchman thinks he is
smart and so has devised a shortcut to verify this. Regardless of the number of horses
in each circle, he just checks the total number of horses along each line of sight.
One evening a traveller comes and meets the watchman. He has four
identical horses and wants to tie them along with these 32 horses. The
watchman refuses initially but agrees later when an incentive is offered.
