I do not think you would have got many marks for that part of the question because you were not going down the right lines but just getting the numbers wrong, you were doing some good numerical sums but not for the right reason. Don't be put off though. I have found with many things in engineering and maths, once you figure out what it is that you are supposed to be working out, it gets a lot easier, and it is far better to learn by trying to work it out with some guidance than to be just told the answer. If that was your first ever attempt, you have some good foundations for future tries.
Have you looked at any of the attempts for some of the other questions to try to get an understanding of the way to approach things?
If you can draw out a sketch of the circuit and mark things on it and post that as a scan, we might be able to give you some pointers on where your thoughts are going wrong.
