I dont understand why you can't believe that I have already graduated and that I am solving questions from a work book (which supposedly contains "tricky questions") to improve my knowledge on this subject.Looks a lot like homework. Show us your best attempt at solving this and we will guide you on what you have correct and what you have wrong. We won't do your homework for you. You won't learn anything that way.
