  2. The first 10 checkpoints require 3 coconuts each, which empties his first sack.
    The next 15 checkpoints require 2 coconuts each, exhausting his second sack.
    The last 5 take 1 coconut each, so he's left with 25 coconuts.

    Great puzzle and great site!

  5. 0... it says he gives 1 coconut FOR EACH sack he is carrying. He has 3 sacks, and 30 checkpoints to clear. He has 30 coconuts in each sack before he leaves.
