I've written these reminders of how percentages work to help people who
haven't used them for some time. In particular, I hope they will help
students who are suddenly faced with percentage calculations in
numerical aptitude tests.
I've split the pages up in the following way:-
What is a price relative? How various index numbers work
January 2003 Some examples
involving ratio and proportion
I've started writing some more pages to help with basic maths, with these two
pages being the first ones.
Please let me know if you would
like more maths help and what kinds of problems you need to be able to
You can email me at firstname.lastname@example.org (but leaving out the
'xyz' which is against robot viruses.) Don't send any attachments please
as I don't open them.
