2/5 of total number of students come by car while 1/4 of the students come by bus. All the other students walk to schools of which 1/3 walk on thier own

and rest are escorted by their parents. If 224 students come to schook walking on thier own how many students come in this school


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
