Question

3/5
of total number of students of a school come by car while 1/4 of students come by bus to school. All the other students walk to school of which 3/4 walk on their own and the rest are escorted by their parents. If 324 students come to
school walking on their own, then how many
students study in that school?​

Answer 1

Answer:

720 students

Step-by-step explanation:

Let total no of students be x.

Students coming by car= 3/5 x

Students coming by bus=1/4 x

Students coming by walk= x- (3/5x + 1/4 x)

                                          = x-17x/ 20

                                          = 3x/20

Students coming to their home by walk  alone= (3/4 of 3x/20)

                                                                             = 9x/ 80

A.T.Q,

      9x /20= 324

   or,  9x= 324 x 20

   or,  x= 324 x 20 / 9

   or,  x= 720

     

    Therefore 720 students study in that school.
