cryptic equation

What is the answer to the following riddle?...

QTK Mark#3 minus QTK Mark#2 = ????

Answer....QTK Mark#1

Are the 'ghosts' from the past now involved with QTK Mark#3???...What involvement have they???

And spare a thought for those employees that have missed out on their entitlements....not enough according to the administrator to pay them out in full!

And what coverage will QTK Mark#3 offer....Sydney only?..cos Melbourne and Qld i understand have been dis connected.

Competitor Smartrans, (the Company that successfully filled the void left by Qtk in China), is expriencing record sign ups from previuos QTK clients atm.

the saga continues...

cheers
