Question

2/5 of total number of students come by car while 1/4 of the students come by bus. And 50 by foot how
many students come in this school

Answer 1

let total students be x
number of students by car is 0.4x
number of students by bus is 0.25x
number of students by
foot = x-0.4x-0.25x=0.35x
given 0.35x as 50 then value of x is 142.85
as the number if students should be an integer.. rounding it off to the nearest integer we get that the school has 143 students
