consider side of smaller square as y and unifiorm width = n
side of larger square = y+2n
area of larger square is A1=(y+2n)^2
Smaller square is A2=y^2 => remaining area= A1-A2=4*n*(y+n)

hence ratio of areas of smaller to remaining is y^2/n*y*(y+n) =25/39=>substitute n= values from options and if we get equations which can be solved then that solution works ,I and II only solve the equations hence C is the answer
:) OA pls
