Question

Out of 40 students in class 8,20% were absent.How many students were present?​

Answer 1

32 students were present.

Explanation:

To find out how many students were present in class 8, we have to find out how many students were absent first.

As the question has already provided us, the number of students who are absent would be
`40 \cdot 20\%`, which equals to
`40 \cdot (20)/(100)` which is 8 students in total who were absent in class 8.

Now that we have found out how many students were absent, simply subtract the number of students who were absent from the total number of students in class 8, which is (40 - 8) = 32 students, and you have the number of students that were present: 32.

Hope this helped!
