A student got 85, 87 and 83 marks in mathematics, physics and chemistry respectively. What is the mean of the obtained marks?
To find the mean (average) of marks, we use a simple formula:
Mean = (Sum of all values) ÷ (Number of values)
Mathematics = 85
Physics = 87
Chemistry = 83
| Subject | Marks |
|---|---|
| Mathematics | 85 |
| Physics | 87 |
| Chemistry | 83 |
| Total | 255 |
Now,
Mean = 255 ÷ 3 = 85
The mean of the obtained marks is 85 marks.
Mean means average. First we add all marks, then divide by number of subjects. It is useful in exams like CBSE, NEET preparation, and school results analysis.
