    In future you must ask in the Ask the Tutor Forum if you want me to answer – this forum is for students to help each other.

    Why are you attempting questions for which you do not have an answer? You should be using a Revision Kit from one of the ACCA approved publishers – they have answers and explanations.

    However, everything needed to be able to answer these questions is covered in my free lectures. The lectures are a complete free course for Paper MA and cover everything needed to be able to pass the exam well.
