Thumbs up Stuck with a Mass and Balance question can you help please!

Can anyone possibly bail me out with this feedback question. I have been struggling with it !

What is the CG as a percentage of the MAC at the DOM for the aeroplane crewed as shown?
Moment Table seat A or B Moment
70kg -35
80kg -40
40kg -45
100kg -50
110kg -55
120kg -60
Seat C
70kg +35
80kg +40
90kg +45
100kg +50
110kg +55
120kg +60
Special equipment
1000kg +15000

There is a diagram which shows a cockpit with the Cpt position as A ,1st Officer as B and Engineer as C ,behind the 1st Officer.

BEM 18000kg
Pilot 100kg
1st Officer 90kg
Flt Engineer 80kg
Special equipment 1000kg
MAC 3m
CG at BEM 6.6m
CG at BEM 20% MAC

The answer is I think supposed to be 9.3% -but being a dope I can't work it out! Can anyone help. Thanks flipper
