Let the total newspaper sold be 100.

No of Newspaper A sold = p
No of Newspaper B sold = 100-p
Total revenue = p*1+(100-p)*1.25
So revenue from paper A = p*1 = p
Revenue percentage from paper
A = (p/(p+(100-p)*1.25))*100
This is equal to r
thus
(p/(p+(100-p)*1.25))*100 = r

r = 100p/(125-0.25p)

by simplifying

r = 400p/(500-p)

This is hard one!!!!
