Hi
David P Bird,
I try to answer your Jeeps in the Desert Problem in respective
thread.
The answer to this puzzle is as follows:
First, the camel carry 1000 bananas to a distance of 200 km. 200 bananas eaten by camel and 200 more need to return back to origin. 600 surplus unload at that point.
Similarly, in second trip, 200 eaten, 200 need for return trip and another 600 unload at same point. Now total 1200 bananas at that point and 800 eaten.
In third trip, camel carry remaining 1000 bananas, travel 200 km and eat 200 bananas.
Load 200 out of 1200 bananas and travel further 333 1/3 km, eat 333 1/3 bananas, need another 333 1/3 bananas for return to previous point and drop 333 1/3 bananas at new point.
Load remaining 1000 bananas, travel 333 1/3 km towards next point and eat 333 1/3 bananas.
Now, 200 + 333 1/3 = 533 1/3 km covered, 666 2/3 bananas loaded and 333 1/3 bananas at new point, total 1000 bananas and 1000 - 533 1/3 = 466 2/3 km away from market.
Load 333 1/3 bananas. At market, total 466 2/3 more bananas eaten by camel and 1000 - 466 2/3 = 533 1/3 bananas sold.
