Basic Cmos circuit question

  1. Feb 10, 2012 #1
    1. The problem statement, all variables and given/known data

    The following question:
    when Vw is VDD=2.5V, what are the output voltages for VX,VY and VZ
    9k816w.png

    2. Relevant equations
    N/A


    3. The attempt at a solution
    this is what i though since the p-mos is ON, VX=VW-|Vtp|
    now the voltage at VY=VX-Vtn
    =VW-|Vtp|-Vtn

    and the answer is wrong, can some one shed some insight into what i am doing wrong, please
