Answer
Total marks in 8 subjects = 8 x 82 = 656.Total marks in 2 English subjects = 2 x 61 = 122.
Total marks in remaining 6 subjects = 656 - 122 = 534.
Average marks in remaining 6 subjects = 534 / 6 = 89.

Fairly straightforward to work out, but fun.
The question should have been reworded to read: can you figure out the students average MARK for the 6 remailn subjects.... the students average in each the six remaining courses was not necessarily 89. In other words, do not pluralize the word "mark"
too early 4 this...
I thought it was rather hard. I did not understand that English Literature and English Language were two completely different subjects. Maybe I should have read it a little more carefully! Ha.
