1) It's not a trick question. There is an answer.
2) You might be helped if I point out the typo and say that the camel can carry 1000lbs, not 100. Sorr-ee!

Ha

Figured it out...

Ok...

There was a mistake in my earlier calculations.

The most hay I can practically get to damascus is 1400lbs, I think.

The most economical way to do so is so that each "cycle" of shuttles, you take exactly one less round trip.

The first go, you go 52.68 miles, and do 19 trips. Leaving you with 9000lbs remaining.
Eventually, you end up 200 miles out from Damascus with 2000 pounds of hay. 3 trips later...
Net result - 1400 lbs of hay

Good lad; we ended up with 1399.xxxxxxx, about the same.
Using exactly the same system, as trips wwhich leave amounts non-divisible by 1000 are wasteful :)
