Answer:38%

Step-by-step explanation:Let x=100%

60% of girls =60x/100

Rest are boys. It means 40 % are boys

40% Of boys =40x/100

Now according to question,

50 %of girls=(50/100)*(60x/100)

=3x/10

Again,

20% of boys=(20/100)*(40x/100)

=2x/25

Now percentage of students who walk to school = (3x/10) + (2x/25)

=19x/50

Putting x=100 %, we get

19x/50

=(19*100%)/50

=19*2%

38%

38% of students walk to school
