    From the problem we have
      When in series,               R1+ R2 = 18   
       When inparallel,             R1R2 / ( R1+ R2) =2
    solving the two equation, we get a Quadraticequation
                             R12 - 9R1 + 18 = 0
    solving we get R1 =6? and R2 = 3? 0r
                          R1= 3? and R2 = 6?
