Question

In an school, 1/25 of the students were absent on a certain day. If 720 students were present on that day, what is the total number of students in the school? Please give explanation.

Answer 1

let total be x
absent students=x/25
we know that,
total students=absent students+present students
x=720+(x/25)
x=(18000+x)/25
25x=18000+x
24x=18000
x=750
total students=750
