For finding the total marks of class 12-A we would do as following:
Therefore,
60 marks × 80 students
=480 marks.
For finding the total marks of 12-C we would do as following:
Therefore,
70 marks × 80 students
=560 marks
To find the total of both classes we would do as following:
=480+560 (marks, this is optional)
=1,040 (marks,this is optional)
Therefore,
The total marks of both classes is 1,040.
