Question

2/5 of total number of student of a school come by car while 1/4 students come by bus to school. all the other students walk to school of which 1/3 walk on their own and the rest are escorted by their parents. If 224 students come to school walking on their own, how many students study in that school?

Answer 1

let the total no. of students be x
number of students who come by car = 2x/5
number of students who come by bus = x/4
number of students who come by walk = x - (2x/5 + x/4) = x - 13x/20 = 7x/20
number of students who come by walk on their own = (7x/20)/3 = 224
7x/60 = 224
x = 224×60÷7 = 1920
