In order to find out the amount of fuel which can be uplifted you have to calculate the MTOM, MLM and tank capacity limitation - the most limiting value obtained from these calculations will be the maximum fuel which can be uplifted.
Note: MZFM does not limit fuel.

BASED ON MAXIMUM TAKE OFF MASS (MTOM):

• MTOM – (ATOM) = 56 300 kg - 46 565 kg = 9735 kg
• ATOM = Dry Operating Mass (DOM) + Traffic Load (TF) + Take Off fuel (TOF) = 29 100 kg + 11 700 kg + 5765 kg = 46 565 kg

* Take Off fuel = Trip Fuel + Contingency Fuel + Final Reserve Fuel + Alternate Fuel = 3000 kg + 215 kg + 1250 kg + 1 300 kg = 5765 kg 

BASED ON MAXIMUM LANDING MASS (MLM):

• MLM – Landing mass = 51 300 kg - 43 565 kg = 7735 kg
• LM = ATOM - Trip fuel = 46 565 kg - 3000 kg = 43 565 kg

=> The most restricting value in based on MLM: 7735 kg

Note: don't forget that the taxi fuel is not part of the take-off fuel! The take-off fuel is the fuel contained at the beginning of the take-off (on the runway). At this location, taxi fuel has already been burned off. If you add the taxi fuel, your result would be 7535 kg (one of the wrong answers).
