Jsck is twice as old as Jill,but in five years time he will only be one and a half times old as Jill.How old are Jack and Jill now/
答
杰克(Jack)现在的年龄是吉尔(Jill)年龄的2倍，五年之后，他的年龄将是吉尔年龄的1.5倍。请问杰克和吉尔现在的年龄分别是多少？
Key: Jack:10, Jill:5.
答
你前面的人名是Jake还是jsck，还有就是你的句子不完整啊，and底下就没有了，前半句的意思是Jake比Jill大一倍，后面要等你句子补充完整了么
答
Jsck应该是Jack吧
设Jack=x ,Jill=y
x=2y
x+5=1.5*(y+5)
解方程组
得X=10
Y=5
所以Jack现在10岁,Jill现在5岁.
