Read the following:There are 3 classes having 20, 25 and 30 students r...
- Class A has a total of 400 marks
- Class B has a total of 625 marks
- Class C has a total of 900 marks

B - If all three classes are combined, what is the total number of students and the overall average marks?

The total number of students is 75 (20+25+30). To find the overall average marks, we need to first find the total marks of all three classes combined, which is 400 + 625 + 900 = 1925. Then, we divide this total by the total number of students, which is 75. So, the overall average marks is 1925/75 = 25.67 (rounded to two decimal places).

C - If a student has scored 30 marks in each class, what is the student's overall average marks?

To find the overall average marks of a student who has scored 30 marks in each class, we need to find the total marks earned by the student and divide it by the total number of classes. The student has scored a total of 30 x 3 = 90 marks overall. The total number of classes is 3. So, the overall average marks of the student is 90/3 = 30.
