In a class of 15 students, the total marks obtained by all the students in a test is 600. Find the average mark of the class.

Options

A. 35
B. 30
C. 45
D. 40

Explanation

To find the average mark of the class, we can use the formula for average:

\[ \text{Average} = \frac{\text{Total Marks}}{\text{Number of Students}} \]

Here are the steps to solve the problem:

**Step 1: Identify the total marks and the number of students.**
- Total marks obtained by all students = 600
- Number of students in the class = 15

**Step 2: Substitute the values into the average formula.**
\[ \text{Average} = \frac{600}{15} \]

**Step 3: Perform the division.**
\[ \text{Average} = 40 \]

**Step 4: State the final answer.**
The average mark of the class is 40.
