Answer 1

Step-by-step explanation:

Total students =1200

No. of girls=45%of 1200

=45/100×1200

=540

No. of boys =1200 - 550

=660

No. of girls using bus=30%of total girls

=30/100×540

=162

No. of boys=25%of total boys

=25/100×660

=165

Total students using bus=no. of girls using bus+ no. of boys using bus

=162+165

=327

percentage of students using bus=total no. of students using bus÷total students

=327÷1200×100%=27.25%
