Wracking Your Brains Out

Three students picked 65 oranges in total.  They picked the same number of apples at the first tree.  At the second tree, they picked 3 times as many as the first tree.  At the third tree, the students had 5 times as many oranges as when they started picking at that tree.   The students picked out only 5 oranges at the fourth tree.

So how many oranges did each student pick at the first tree?

Just wracking your brains out!
