The ratio of the number of boys to the number of girls who
are present in a class is 3:2. The number of girls who are absent is 15, which is 25% of the total number of students in the class. If no boy is absent, then find the number of boys in the class.Solution
Total number of students = 15/0.25 = 60
Number of students who are present = 60 – 15 = 45
