Question

In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is of the number of students of 8 years of age which is 48. What is the total number of students in the school?

Answer 1

The answer is 100.

Let the number of students be x

Number of students above 8 years of age = (100 - 20)% of x = 80% of x.
=> 80% of x = 48 + 2/3 of 48
=> 80/100 x = 80
=> x = 100

Answer 2

the total number of students in the school are 100.....
Let the number of students be x. Then,
Number of students above 8 years of age = (100 - 20)% of x = 80% of x.
 80% of x = 48 +2/3of 48
80 /100x = 80

x = 100.
