Let A be x.
Given C is 10℅ less than A, so 

C=x-(10/100)x
  =9/10x

Given C is 20℅ more than B, so

C=B (20/100)B
9/10x=(12/10)B  .............{C=9/10x}
B=(9/10x)/(12/10)
  = (9/10x)×(10/12)
  =3/4x

Now, A=x and B=3/4x

We have to find difference between A and B.

i.e. A–B
   = x–3/4x
   =1/4x
   =25℅
