Last week, a farmer shipped 10 boxes of pomelos which had 240 pomelos in all. This week, the farmer shipped 20 boxes. How many dozens of pomelos did the farmer ship in all?
How many pomelos were in a box? ** There were 240/10 = <<240/10=24>>24 pomelos in a box.
How many dozens of pomelos were in each box? ** This means that each box has 24/12 = <<24/12=2>>2 dozens of pomelos since 1 dozen is equal to 12.
How many boxes did the farmer ship in total? ** The farmer shipped a total of 10 + 20 = <<10+20=30>>30 boxes.
How many dozens of pomelos did the farmer ship in all? ** Thus, the farmer shipped a total of 30 x 2 = <<30*2=60>>60 dozens of pomelos.
