- About your question
Without a little more information on your scenario, such as the kind of note that you are wanting to work out the interest on, it is very hard for people to help you, and give you the aid that you require.
By adding the much needed details to your inquiry, or even by re-posting the entire question again, you may find that more people will be able to provide an answer to your problem.
- Working out interest
If, however, you do not have the time to do this, then have a look at this link: http://ibkb.interactivebrokers.com/node/39. Providing lots of details on the various aspects of accountancy, including a step by step guide on working out interest, this website is one of the better ones out there, as it seems to be the most suited to your needs.
Another alternative in gaining help would be to go to your local library, which should provide you with a range of books, all of which will assist you in finding the answer that you require.
Should you find that neither of these options help you, then your only remaining thing that you can do is to go and speak to your subject tutor, as this sounds very much like a question that may have been set to aid you in the self study aspect of a course.
Although this may seem daunting, you must remember that this is what your tutor is there for, and that by showing them the areas that you are struggling with, you are helping them to help you; doing this does not mean, nor show, that you are failing the course, as your tutor should be ready to explain. It does, however, emphasize the kind of student that you are; conscientious, and willing to work hard to do well within a subject.
