Percentage & Averages
In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is 2/3 of the number of students of 8 years age which is 48. What is the total number of students in the school?
Student of age more than 8 years = 48 x = 32
Total student 8 years old or above=32+48=80
Now 20% of student is below 8 years old so 80% of student=80
So total Student=100
