Answer:
a. 6th class :-
Total students = 350+50
= 400
Students who use school bus = 350
Percentage = Students who use school bus/Total students
= 350/400 × 100
= 7/8 × 100
= 7 × 12.5
= 87.5%
7th class :-
Total students = 300+100
= 400
Students who use school bus = 300
Percentage = Students who use school bus/Total students
= 300/400 × 100
= 3/4 × 100
= 3 × 25
= 75%
8th class :-
Total students = 250+100
= 350
Students who use school bus = 250
Percentage = Students who use school bus/Total students
= 250/350 × 100
= 5/7 × 100
= 500/7%
9th class :-
Total students = 300+150
= 450
Students who use school bus = 300
Percentage = Students who use school bus/Total students
= 300/450 × 100
= 6/9 × 100
= 600/9%
10th class :-
Total students = 250+200
= 450
Students who use school bus = 250
Percentage = Students who use school bus/Total students
= 250/450 × 100
= 5/9 × 100
= 500/9%
