Solution:
1. Determine the number of students with no siblings:
- Total students = 300
- Percentage with no siblings = 35%
- Calculate number of students with no siblings: 300 \times \frac{35}{100} = 105
2. Calculate the number of students with siblings:
- Number of students with siblings = Total students - Students with no siblings
- Students with siblings = 300 - 105 = 195
