Answer 2

Answer:

16.8

Step-by-step explanation:

Mean age of boys = 16

No of boys = 15

Mean age of boys=total age of boys / no of boys

So total age of boys = mean x number

=16x15=240

Similarly total age of girls = mean age of girls x no of girls

=18x10=180

So total age of students = total age of boys + total age of girls

=240+180

=420

Total no of students = no of boys + no of girls

=15+10=25

So average age of students =total/number

=420/25

16.8
