Ratios: x = 100 pounds, y = 60% of x, z = 40% of x

[rudyard]

Hi,

I'm having real problems with the following equation- please help!

Imagine...
x=100 pounds
y = 60% of x
z = 40% of x

I know that if I apply the percentages now, that y = 60 pounds and z = 40 pounds.
However, if I know that y costs twice as much as z, what values am I left with for y and z?

If I double y I get 120 pounds which is more than the total of 100 pounds!!

Any help gratefully appreciated!

Re: Ratios

First off, there is no equation visible in your post. Secondly, you need to distinguish the difference between "pounds" and "cost". It appears to me that you haven't provided all the information given in the original problem. Is there something missing?
