Answer 1

• 400 students

Given :

• Total strength of the school : 500 students
• Amount of students absent : 20%

To find :

• Number of students that were present in the school.

Solution :

ATQ,

20% of the students were absent so in order to find the number of students who were present, we're firstly required to find the number of students absent and then deduct the strength from the total , resulting in the required number of students that were present.

• 
  `\rightarrow \: 20\% * 500 = 100`
• 
  `\rightarrow \: 500 - 100 = 400`

Thus, a total of 400 students which make up 80% of the total strength were present.
