Answer

To solve the problem of finding the number of people who read at least one type of magazine and are over 35 years in age, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Data**:
We have data on the number of people who read sports magazines, film magazines, and both. We need to focus on the age group over 35 years.

2. **List the Numbers**:
- Number of people who read sports magazines: 50
- Number of people who read film magazines: 40
- Number of people who read both magazines: 40
- Number of people who read sports magazines and are over 35: 50
- Number of people who read film magazines and are over 35: 30
- Number of people who read both magazines and are over 35: 20

3. **Add the Relevant Numbers**:
To find the total number of people who read at least one type of magazine and are over 35, we will add the numbers of people who read:
- Sports magazines (over 35): 50
- Film magazines (over 35): 40
- Both magazines (over 35): 40
- Sports magazines (not over 35): 50
- Film magazines (not over 35): 30
- Both magazines (not over 35): 20

However, since we are interested in those who read at least one magazine and are over 35, we will only consider the relevant numbers for those over 35.

4. **Perform the Calculation**:
The calculation will be:
\[ 50 \text{ (sports)} + 40 \text{ (film)} + 40 \text{ (both)} + 50 \text{ (sports)} + 30 \text{ (film)} + 20 \text{ (both)} = 230 \]

5. **Conclusion**:
Thus, the total number of people who read at least one type of magazine and are over 35 years old is **230**.

### Final Answer:
The number of people who read at least one type of magazine and are over 35 years in age is **230**.
