Richard, Jerry, and Robert are going to share 60 cherries. If Robert has 30 cherries, and has 10 more than Richard, how many more cherries does Robert have than Jerry?
Since Robert has 30, then 60 - 30 = <<30=30>>30 cherries are left to be shared by Richard and Jerry.
Richard has 30 - 10 = <<30-10=20>>20 cherries since Robert has 10 more cherries than him.
Jerry has 30 - 20 = <<30-20=10>>10 cherries.
So Robert has 30 - 10 = <<30-10=20>>20 more cherries than Jerry.
