Question
The total number of students to the total number of
teachers in Universities A and B is in the ratio 25:4. Additionally, the number of teachers in University A to those in University B is in the ratio 3:1. Given that the total number of students across both universities is 5000, determine the difference in the number of teachers between University A and University B.Solution
ATQ;
Total students : total teachers = 25 : 4
Total students = 5000
So total teachers = (4/25) × 5000 = 800
Ratio of teachers in University A : B = 3 : 1
Difference = 800 × (3−1)/(3+1) = 400
