Question

In a class , 80 students passed and the rest failed if 80% of the students failed, find the number of students in class

Answer 1

Solutions :-

Given :
Total number of students passed = 80
Total percent of failed students = 80%

Find the total percent of students passed :-

Percent of Passed students = (100 - 80)%
= 20%

Let the total number of students in class be x


According to the question,

=> 20% of x = 80
=> 0.2 × x = 80
=> x = 80/0.2 = 400


Hence,
Total number of students in class = 400

Given ;-
• Passed student's Total Number = 80
• Failed student's total percentage = 80%

Now ,
Finding the total number of students passed ;-

So ,
% of students passed = { 100 - 80 }% = 20%

Now ,
Assuming the total number of students in class as y.

Then ,
According to the Question ;-

$= > 20\% \: of \: x \: = 80$

Therefore ,
The total number of Students in class is 400.
