Options

B. 850
C. 950
D. 900

Answer

To find out how many students enrolled for the computer course in 2005, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Total Number of Students:**
We need to first calculate the total number of students enrolled across all colleges. According to the data provided, the number of students from different colleges is:
- College 1: 480
- College 2: 350
- College 3: 380
- College 4: 500
- College 5: 540

We will add these numbers together:
\[ \text{Total Students} = 480 + 350 + 380 + 500 + 540 \]

2. **Perform the Addition:**
Now, we will perform the addition:
\[ 480 + 350 = 830 \\ 830 + 380 = 1210 \\ 1210 + 500 = 1710 \\ 1710 + 540 = 2250 \]
Thus, the total number of students is **2250**.

3. **Calculate 40% of the Total Students:**
Since 40% of the students enrolled in the computer course, we will calculate 40% of 2250:
\[ \text{Number of Students Enrolled} = 40\% \text{ of } 2250 = \frac{40}{100} \times 2250 \]

4. **Simplify the Calculation:**
We can simplify the calculation by canceling out the zeros:
\[ = \frac{40 \times 2250}{100} = 4 \times 225 \]

5. **Perform the Final Multiplication:**
Now, we will multiply:
\[ 4 \times 225 = 900 \]
Therefore, the number of students enrolled for the computer course is **900**.

### Final Answer:
The number of students enrolled for the computer course in 2005 is **900**.
