It is clear. There are 81 apple trees. 1st tree has 1 apple, 2nd tree has 2 apples, 81st tree has 81 apples. Distribute the "trees" (not apples) among 9 people so everyone gets equal amount of apples. (which is 369). This is how i started. 5th person gets 369 an others are close to that amount. It might be a wrong approach but anyways…
