Question

A particular high school has 1500 students 50 teachers and 5 administrators. If the school grows to 1800 students and the ratios are maintained, then find the number of teachers and administrators

Answer 1

Administrators : teachers : students

= 5 : 50 : 1500

= 1 : 10 : 300

If the school grows to 1800 students then 10 parts = teachers

1 part = administrators

300 parts = 1800

1 part = `1800/300` = 6

10 parts = 6 × 10 = 60

So, if the school grows to 1800 students the new ratio is administrators : teachers : students

6 : 60 : 1800
