Question

A certain school has 1200 students and teachers in total.if there are 20% teachers,find the number of students in a school.​

Answer 1

Given,

Total students and teachers = 1200

Total teachers = 20% of 1200

To find,

Number of students

Solution,

We know that there are a total of 1200 students and teachers out of which 20% are teachers

So, the number of teachers = 20% of 1200

the number of teachers = 240

The total number of students = Total number of students and teachers - total number of teachers

Putting the values given above

we will get,

The total number of students = 1200 - 240

The total number of students = 960

Hence, the number of students in a school are 960
