The total number of students in a school is 1650. 70% of the pupils are boys. How many girls are there in the school.

To determine the number of girls in the school, follow these steps:

1. **Calculate the number of boys**:
   - 70% of the pupils are boys.
   - Number of boys = 70% of 1650
   \[
   \text{Number of boys} = 0.70 \times 1650 = 1155
   \]

2. **Calculate the number of girls**:
   - Total number of students = 1650
   - Number of girls = Total number of students - Number of boys
   \[
   \text{Number of girls} = 1650 - 1155 = 495
   \]

Thus, there are 495 girls in the school.
