Hi,

I'm having real problems with the following equation- I'm sure there will be
a way of working this out (possibly even without the use of Excel)...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!
