Riddle #1 :

you have been given the task of transporting 3,000 apples 1,000 miles from appleland to bananaville. your truck can carry 1,000 apples at a time. every time you travel a mile towards bananaville you must pay a tax of 1 apple but you pay nothing when going in the other direction (towards appleland).

what is highest number of apples you can get to bananaville?

probably because the owner wants to get rid of it

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
