Machine A fills 120 bottles in every 40 seconds and Machine B fills 100 bottles in every 20 seconds. If the two
machines run simultaneously fill, how many seconds will it take to produce a total of 200 bottles?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

Lets take 5 seconds as a quantum of time.

In 5 seconds, machine A fills 120%2F8 = 15 bottles,
      while a machine B fills 100%2F4 = 25 bottles.


Thus the two machines fill 15 + 25 = 40 bottles in each 5 seconds, working together.

It will take 5*5 = 25 seconds for the two machines to fill 200 bottles, working together.
