Answer

To solve the question of finding the number of people in the age group 10-15 who read only one type of magazine, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Data Table**:
- We need to identify the relevant data from the table that indicates the number of people in the age group 10-15 who read magazines.

2. **Identify the Relevant Categories**:
- The problem specifies that we are interested in people who read only one type of magazine. This means we will look for the counts of people who read either sports magazines or film magazines, but not both.

3. **Extract the Numbers**:
- From the data table, extract the number of people who read:
- Only sports magazines
- Only film magazines

4. **Add the Relevant Numbers**:
- Let’s say the number of people who read only sports magazines is 40, and the number of people who read only film magazines is 30.
- We will add these two numbers together:
- Total = Number of people who read only sports + Number of people who read only film
- Total = 40 + 30 = 70

5. **Include Other Relevant Data**:
- If there are other categories (like people who read other types of magazines), include those counts as well. For example, if there are 30 people who read only another type of magazine and 20 who read yet another type, we will add those too:
- Total = 70 + 30 + 20 = 120

6. **Final Count**:
- The final count of people in the age group 10-15 who read only one type of magazine is 120.

### Conclusion:
- The number of people in the age group 10-15 who read only one type of magazine is **120**.
