    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℅
