Hello all. I feel like such a retard, but there's an example problem in my book with the answer, and I just don't know how they are getting the answer. I suppose it's due to my lack of mathematical skills. I was wondering if someone could guide me on how they got the answer.(adsbygoogle = window.adsbygoogle || []).push({});

The answer is at the bottom. I just don't understand how they are getting IofA, IofB, and IofH. I do realize that I = V/R, but I'm confused because their are 2 unknown variables in each question. I apologize in advance for my stupidity. :(
