David obtained 76, 65, 82, 67 and 85 marks (out of 100) in English, Mathematics, Physics, Chemistry and Biology. What are his average marks?
Explanation
To calculate David's average marks, we need to add up all his marks and divide by the number of subjects:
English: 76
Mathematics: 65
Physics: 82
Chemistry: 67
Biology: 85
Total marks: 76 + 65 + 82 + 67 + 85 = 375
Number of subjects: 5
Average marks: 375 ÷ 5 = 75
So, David's average marks are: 75
