    The delay of the FA in Bit-Serial Adder is 20ns. Compute
    fmax if the setup and hold time of the flipflops is 5ns.
    What will be the total time to compute sum of 8 bit
    operands?

    Where did that number come from? SHOW YOUR WORK!!!!

    You should start with a diagram of the circuit you are working with. Not every bit-serial adder is implemented identically.
