Answer:
105 students
Explanation:
The computation of the number of students left the school is given below:
Let us assume the total students be x and 100%
Left percentage = 84%
Remaining percentage = 100% - 84% = 16%
Now according to the question
16% of x = 20
0.16x = 20
x = 20 ÷ 0.16
x = 125
Total students 125
Those who left is
= 84% of 125
= 105 students
