Enrich Your Itineraries
We can tour a good part of the seventh arrondissement without using any
arteries which start with the letter "S." The route proposed here shares a
street named after a surgeon who was the director of the School of Military
Medicine and published in 1874 a work entitled The Recovery of France.

Let's Go France!
On occasion of the Soccer World Cup, 321 fans came to the small town of
Touraine, got off at Austerlitz Station and rushed to the Parc des Princes
stormed three empty train cars of the metro line Austerlitz-Auteuil (today
extended to Bologne - Jean-Jaures, but this, in our case does not solve our
problem). In the throng, everyone has lost their friends and at the next
station (Jussieu) the fans try to regroup. Thus:
1. Half of the travelers in the first train car migrate to the third;
2. A quarter of the travelers in the second car are divided half-and-half
between the first and third;
3. Of a third of the travelers in the third train car, one third of them go to
the first and two-thirds go to the second. At the end of their regrouping, it
turns out that there is, in every train car, the same number of supporters as
when they left.
How can 321 fans be distributed across three train cars?
