Dividends

The three friends divided the win by the invested money. Karlos got three-eighths, John 320 per mille, and the rest got Martin. Who got the most, and which got the least?

Final Answer:

a = Karlos
b = Martin

Step-by-step explanation:

$$\begin{gathered} k=3/8=\frac{3}{8}=0.375 \\ j=320‰=\frac{320}{1000}=\frac{8}{25}=0.32 \\ m=1-k-j=1-0.375-0.32=\frac{61}{200}=0.305 \\ m<j<k \\ a=Karlos \end{gathered}$$

$b=Martin$
