Jug water volume

We filled half the jug with water. We poured this water into quarter-liter cups. Five cups filled to the brim, the sixth only half its volume. What is the volume of the pitcher?

Final Answer:

x =  2.75 l

Step-by-step explanation:

$$\begin{gathered} V_1=1/4=\frac{1}{4}=0.25\text{l} \\ {V}_2=5\cdot V_1+V_1/2=5\cdot 0.25+0.25/2=\frac{11}{8}=1.375\text{l} \\ x=2\cdot V_2=2\cdot 1.375=\frac{11}{4}\text{l}=2.75\text{l} \end{gathered}$$
