Question

the student - techer ratio in a school is45:2 if there are 4050 students in the school,how many teachers should be there

Answer 1

given for 45 students 2 teachers are required
I.e., number of teachers required for 45 students = 2 teachers
assuming
number of teachers required for 1 student = 2/45
now,
number of teachers required for 4050 students =4050*2/45
=90
therefore 90 teachers are required for 4050 students

Answer 2

Here is your answer

Let the number of teachers in school is x

Ratio of student to teacher = 45 : 2

Total students is 4050

ATQ. 45 : 2 = 4050 : X

45 X =4050 x 2

X =4050x2/45

X = 180

Hence Total numbers of teachers is 180
