Question
In a class, the ratio of boys to girls present is 4:3. The
number of girls who are absent is 21 which is 30% of the total number of students. If all boys are present, find the number of boys in the class.Solution
Total number of students = 21/0.30 = 70
Number of students who are present = 70 – 21 = 49
Therefore, number of boys in the class = 49 × 4/7 = 28
