Step-by-step explanation:
first arrange the numbers
25,40,68,70,78,85,85,95,98,100
N= 10
median= (n+1)/2

=5.5
the average between 5th position and 6th
which is 78 and 85
=(78+85)/2
=81.5

If you don't know what this is or how to apply it, go to the website "Khan Academy" and watch his video(s) on it. I would suggest going to that site whenever you don't understand something in math :)
I'll just be giving you the answers and won't explain what I'm doing, but please do go to Khan Academy to find out how to do it on your own!!
Anyway, onto the answers.
1) a = 12.5, b = 5.7, c = 13.7.
