Category status based on sub category

Hi All,
I have a table like below. I need to show the overall status of the category based on the sub- category. 
1. If all the sub-categories are completed then Category is completed.
2. If each sub category is having 3 different status, category status should be Risk.
3. If sub categories having same status more than the other status, then category should be the Most status.
For Pen- Risk
Pencil- Completed
Marker- In progress.
TIA.
