Question

The ratio of students to teachers at a school is 19 : 1. At this school, there are 400 people (teachers and students). How many of these 400 people are students? (enter number only, without the unit)

Answer 1

380

Explanation:

Let 19x = no. of students

x = no. of teachers

Then, x + 19x = 400

20x = 400

x = 20

19x = 19(20) = 380

Answer 2

There are 380 students and 20 teachers.
