Answer:

22 2/3

Explanation:

Total age of students=55×21

=1155

Total age of girls =25×19

=475

Total age of boys =1155-475

=680

Total no of boys = Total no students-Total

no of girls

=55-25

=30

Average age of boys = Total age of boys / Total no of boys

= 680/30

= 22 20/30(mixed fraction)

=22 2/3( cancel 20 and 30)
