猜猜看（英语）
Jack is twice as old as Bill,who is eight years younger than Ben, who is four years younger than Ted, who is half as old again as Jack. How old is Bill?
最后一句什麽意思?如何算?

比杰克大半倍
设杰克此时2X岁,
由Jack is twice as old as Bill可知Bill为x岁,
由于who is eight years younger than Ben,所以Ben为x+8 岁
由于who is four years younger than Ted,所以Ted为x+12岁
由最后一句,就有
x+12=1.5x*2
x=6
Bill is 6 years old.
