## Task 4 - 050824

Fishermen Adam, Bauer, Christiansen, and Dahse (abbreviated as $A, B, C, D$) weigh their catch and find:

(1) $D$ caught more than $C$.

(2) $A$ and $B$ together caught exactly as much as $C$ and $D$ together.

(3) $A$ and $D$ together caught less than $B$ and $C$ together.

Order the catch results $a, b, c, d$ of the fishermen $A, B, C, D$ by size! (Start with the largest result!)
The statements (1), (2), and (3) can be written as follows:

(1) $d>c$,

(2) $a+b=c+d$,

(3) $a+dd$, from (2) and (4) it follows that (5) $c>a$ and

from (4), (1), and (5) it finally follows that $b>d>c>a$.
