Calculation of the Number of Students Studying English

To calculate the number of students studying English in the school, we need to determine the percentage of students studying English among the middle and senior level students.

According to the given information, 30% of the middle and senior level students study German, while the rest study English.

We also know that 28% of the total students in the school are elementary school students.

To calculate the number of students studying English, we need to subtract the number of elementary school students from the total number of students and then multiply it by the percentage of students studying English among the middle and senior level students.

Let's calculate it step by step:

1. Calculate the number of elementary school students: - Total number of students: 250 - Percentage of elementary school students: 28% - Number of elementary school students = 250 * 28% = 70 students.

2. Calculate the number of middle and senior level students: - Total number of students: 250 - Number of elementary school students: 70 - Number of middle and senior level students = Total number of students - Number of elementary school students = 250 - 70 = 180 students.

3. Calculate the number of students studying English: - Percentage of students studying German: 30% - Percentage of students studying English: 100% - 30% = 70% - Number of students studying English = Number of middle and senior level students * Percentage of students studying English = 180 * 70% = 126 students.

Therefore, there are 126 students in the school who study English.
