A4 We filled 240 glasses with juice, each containing 0.75 liters. How many glasses of 0.5 liters would we need to fill with the same amount of juice?
(A) 120
(B) 36
(C) 180
(D) 360
(E) 280
A4. We calculate the amount of juice $240 \cdot 0.75 \mathrm{l}=180 \mathrm{l}$, which we divide into half-liter glass bottles. So, $180 \cdot 2=360$ bottles.
