Solve by any means, one of the problems in the Nine Chapters: There is a reservoir with five channels bringing in water. If only the first channel is open, the reservoir can be filled in 1/3 of a day. The second channel by itself can fill the reservoir in one day, the third channel by itself in 1.5 days, the fourth one in three days, and the fifth one in five days. Hint: Draw a diagram/figure. Question to answer: If all the five channels are open together, how long will it take to fill the reservoir ?
