Detailed explanation of solution :-

Let's understand!

We know that there are 20 teachers and 500 students in a school , We are asked to find the ratio of students and teachers.

How to solve ?

Let's make a fraction of teachers and students in school and then we will simplify it !

Calculations :-

Fraction of teachers to students :-

$\sf \leadsto\dfrac{20}{500}$

Cutting off zeroes, We are left with :-

$\sf \leadsto\dfrac{ 2\cancel{0}}{50 \cancel{0}}$

$\sf \leadsto\dfrac{ 2 }{50}$

Further simplifying,

$\sf \leadsto \cancel{\dfrac{ 2 }{50}}$

$\sf \leadsto \purple{1 : 25}$

Thus, The ratio of teachers to students in the school is 1 : 25 (Option - C).
