Petri Net exam papers needed to be solved -- 2

Hi there I have some past exams of a subject which is all about petri nets and coloured petri nets and its modelling which are attached. I need some who can solve these exams plus other exams which I'm going to provide in case you have a background in this. If you have a background in Petri nets and you think you can do it. I will include you with the lecture materials, but the lecture materials aren't good enough to teach how to solve them that's why I'm seeking for help here. My exam is on the 24th, and I want somebody who can solve it asap with full explanations so I can understand the solutions. Thank you.
