Question

2% of the total number of students of come by car while One by fourth of the rest of the students come by bus and the remaining 180 students come by walking the total number of students is dash

Answer 1

let total student be x
student come by car 2% of x= 2/100 × x = x/50
student come by bus = 1/4 of x = x/4
walking = 180

total student = x/50 + x/4 + 180
x = x/50 +x/4 + 180
x - x/50 - x/4 = 180
100x-2x-25x = 180 × 100
73x = 18000
x = 246 approx....
