Answer 1

Answer: 1,250

Step-by-step explanation:

Given: The total number of students in the school= 25,000

Since each class has 10 students , therefore, the number of classes in the school= $\frac{25000}{10}=2500$

Also, Each student takes 2 classes a day, thus the number of classes taken by total teachers in a day = $2\times2500=5000$

Also, each teacher teaches 4 classes.

Then the number of teachers in the school =$\frac{5000}{4}=1250$

Hence, the number of teachers are at  Big Big School = 1,250
