Answer:

105 students

Step-by-step 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
