Find the number of teachers

Answer 1

Given, Ratio of teachers: male: female = 2: 17: 18

Ratio of students = 17 + 18 

                             = 35

Total numbers of students = 665

                                            = 665/35

                                            = 19

Number of teachers = 19 * 2

                                   = 38


Hope this helps!
