1. Answer:

   Ratio of students in 6A and 6B =6:11(given)

   According to the question

   6A/6B=6/11

   Let 6A be x

   Let 6B be y

   or, x/y =6/11

   when 6B has 25 more students than 6A

   or, 6B =6A + 25

   or,y = x+25(as 6B is assumed as y and 6A as x)

   by the problem,

   x/x+25=6/11

   or,11*x=6*(x+25)

   or,11x=6x+150

   or,11x-6x=150

   or,x=30

   Students in 6A = 30

   therefore students in 6B =x+25=30+25=55

   6A:6A+6B=30:55+30=6:17
