Your wish is my command Laxieqv, here is an especially "non-understandable" word problem for you!
Two machines are sawing wood but due to space limitations only one of the two machines can operate. Machine A is used for the first shift and the other machine for the second shift, while both work half of the third shift. Machine A can do the job in 12 days if it worked two shifts and Machine B can do the job in 15 days if it worked two shifts. How many days will it take to do the job with the current work schedule?
I'm going to answer nature's call while I let you blokes solve this one...

3rd shift, is what is confusing.
if 1/2 of 3rd shift A works and 1/2 B works, it is 80/9 = 9
if only for 1/2 of the shift both work (since both can't work simultaneously - say 1/4 A and 1/4 B) - Ans would be 32/3 = 11
