## Task 3 - 180523

Four Cooperative Departments of Plant Production (KAP), denoted as $A, B, C$, and $D$, together own 92 tractors.

If $B$ transfers three of its tractors to $A$ and four of its tractors to $D$ for better utilization, then all four KAPs will have the same number of tractors.

How many tractors did each of the four KAPs originally have?
Due to $92: 4=23$, after lending, each of the four KAP has 23 tractors. Since $C$ neither received a tractor nor gave one, she originally had exactly 23 tractors.

A had 3 tractors less than 23, so 20 tractors. $D$ had 4 tractors less than 23, so 19 tractors. $B$ had 7 tractors more than 23, so 30 tractors.
