    Answer: 82

    Step-by-step explanation:

    72 times 6 is equal to 432

    6 plus 2 is 8

    74.25 times 8 is equal to 594

    If you minus 594 and 432 you get 162

    162 is total marks for both subjects

    162 minus 80 you get 82 which is the marks for the 8th subject

    Hope it taught you something ...
