Question

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

Answer 1

The ratio of Students : teachers : administrators = 1500 : 50 : 5.

The new ratio of Students : teachers : administrators = 1800 : new teachers : new administrators.

Given the ratios are maintained. i.e., they are proportional.

∴ For 1800 students 60 teachers and 6 administrators are needed.
