Question

There are 150 teachers in a school for 3,000 students. Find the student to teacher ratio.

• A. 20 : 1
• B. 21 : 1
• C. 1 : 20
• D. 5 : 18

Answer 1

The correct option is A 20 : 1

Given, number of teachers = 150
and, number of students = 3,000
Reducing the ratio to lowest form we get ,
$\Rightarrow \frac{3,000÷150}{150÷150}=\frac{20}{1}$

Hence, the student to teacher ratio is 20 : 1.
