## Task 1 - V10811

The new double-decker articulated train of our State Railway weighs a total of $129 \mathrm{Mp}$ (unladen weight) and has seating for 640 passengers. An old-style D-train car weighs $40 \mathrm{Mp}$ and offers seating for 64 passengers.

By what percentage is the "seat weight" (unladen weight per seat) of the new double-decker articulated train lower than that of an old-style D-train?
Doppelstock-Gliederzug: Leergewicht je Sitzplatz $L_{1}=\frac{129}{640} \approx 0.2016$

D-Zug-Wagen: Leergewicht je Sitzplatz $L_{2}=\frac{40}{64} \approx 0.625$

$L_{1}$ is equal to $33.22\%$ of $L_{2}$. The seat weight in the double-decker train is thus 67.75 percent lower than in an old-style D-Zug.
