Do you have any ideas? It's quite hard to 'help' if you don't offer some idea of what you are thinking and where you are stuck?
Tell us a little more about which aspect you need help with.

You have posted 4 very different series of problems with marking scheme - but have not shown any work/thought towards solution of the problem.

Are these problems from an exam that you are supposed to pass? For us to help you - you need to tell us where do we need to start.
