Let , Total no.of students study in school =  x

Total number of the students in the school come by car = 2x/5

Total number of the students in the school come by bus = x/4

Total number of students walk to school = 
x -(2x/5 + x/4 )  =
 x-  (8x+ 5x) /20 = x-(13x)/20
(20x- 13x)/20
7x/20

Total number of students come to school on their own = 1/3×7x/20 = 7x/60

Total number of students come to school on their own = 224 , (given)

7x/60 =224
x =  224/ 7 × 60
x = 32 × 60
x = 1920
Total number of students study in school = 1920
