Question
The total number of teachers to the total number of students in Schools X and Y is in the ratio 40:9. Additionally, the number of students in School X to those in School Y is in the ratio 3:2. Given that the total number of teachers across both schools is 400, determine the difference in the number of students between School X and School Y.
Solution
ATQ;
Total teachers : total students = 40 : 9
Total teachers = 400
So total students = (9/40) × 400 = 90
Ratio of students in School X : Y = 3 : 2
Difference = 90 × (3−2)/(3+2) = 18
