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%
