In a primary school, there are three groups of people - teachers, lower primary students and upper primary students.There are 20 teachers and 600 upper primary students. Given that upper primary students make up 1/3 of the student population, how many people are there in the primary school?
To find the total number of people in the primary school, you need to account for teachers, lower primary students, and upper primary students.
You already know there are 20 teachers and 600 upper primary students. Since upper primary students make up 1/3 of the student population, you can calculate the total number of students in the upper primary level:
Total Upper Primary Students = (1 / 3) * Total Student Population
600 = (1 / 3) * Total Student Population
Now, to find the total student population, you can multiply both sides by 3:
Total Student Population = 600 * 3
Total Student Population = 1800
Now that you know the total student population, you can find the number of lower primary students:
Total Lower Primary Students = Total Student Population - Total Upper Primary Students
Total Lower Primary Students = 1800 - 600
Total Lower Primary Students = 1200
Now, to find the total number of people in the primary school, add the teachers, upper primary students, and lower primary students:
Total People = Number of Teachers + Total Upper Primary Students + Total Lower Primary Students
Total People = 20 (teachers) + 600 (upper primary students) + 1200 (lower primary students)
Total People = 1820
There are 1820 people in the primary school.
