Question

There are 550 students how many teachers were there be in ratio form

Answer 1

The ratio of teacher to student is equivalent so teacher to the student ratio is same for all the school A, B, C and D.

Equate the teacher to school ratio for school A and school C to obtain the number of teachers in school C.

`\begin{gathered} (15)/(330)=(x)/(550) \\ x=(15\cdot550)/(330) \\ =25 \end{gathered}`

The number of teacher is school C is 25.

Equate the teachers to students ratio for the school A and school D to obtain the number of students in school D.

`\begin{gathered} (15)/(330)=(36)/(y) \\ y=(36\cdot330)/(15) \\ =792 \end{gathered}`

The number of students in school D is 792.
