Hi, based on your theory and practical marks your total out of 400 marks is 356(MUSIC 100 marks+PAINTING 91 marks+ENGLISH 79 marks+POLITICAL SCIENCE 86 marks) marks that is 89%.
If you wish to takeke admission in any subject except Music, 5% marks will be deducted from 89%  as you can include music in your best of four calculation only if you opt for Honours in Music. Painting/fine arts isn't mentioned in the list A provided by DU in order to calculate best of four.
So 89% - 5% is 84%.
Your final percentage is now 84%
In order to know more about how to calculate best of four and view the list A, refer to the article in the link:
