Concept: Ratio is the comparison of two quantities, having the same units, and which shows the number of times one value contains within the other.
There are 102 teachers in the school.
3300 students attend this institution.
Ratio of the number of teachers to the number of students, we get
⇒number of teachersnumber of students=1023300
 On further simplifying the fraction, we get
                                =17550
∴ Ratio = 17:550
Hence, the correct answer is option 3.
