Greek railwayman

Lewis has worked for Slovak Railways since 2000. His salary is 950 €. His colleague Evgenias has worked for Greek State Railways since 1984 and earns 5700 € per month.

Calculate:
a) how many times more does Evgenias earn than Lewis?
b) how many times more does Evgenias earn than Lewis if Evgenias receives both a 13th and 14th month salary and Lewis does not?
c) how many euros more does Evgenias earn than Lewis per year?
d) how many working days per year does Evgenias need to work to earn as much as Lewis earns in a year, if they work 7.5 hours a day?
e) by what percentage is Evgenias's salary higher than Lewis's?
f) by what percentage is Lewis's salary lower than Evgenias's?

Final Answer:

A =  6
B =  7
C =  4750 eur
D =  60 d
E =  500 %
F =  83.3 %

Step-by-step explanation:

$$\begin{gathered} s=950 \\ g=5700 \\ A=g/s=5700/950=6 \end{gathered}$$

$B=(14\cdot g)/(12\cdot s)=(14\cdot 5700)/(12\cdot 950)=7$

$C=g-s=5700-950=4750\text{eur}$

$D=\lfloor 365\cdot s/g\rfloor =\lfloor 365\cdot 950/5700\rfloor =60\text{d}$

$E=100\cdot \frac{C}{s}=100\cdot \frac{4750}{950}=\frac{100\cdot 4750}{950}=\frac{475000}{950}=500\%$

$F=100\cdot \frac{C}{g}=100\cdot \frac{4750}{5700}=\frac{100\cdot 4750}{5700}=\frac{475000}{5700}=83.3\%$
