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) = 875 000 lb - 775 510 lb = 99 490 lb
• Actual Take off mass ATOM = Dry Operating Mass (DOM) + Traffic load (TL) + Take Off fuel (TOF) = 394 100 lb + 155 215 lb + 226 195 lb = 775 510 lb

BASED ON MAXIMUM LANDING MASS MLM:

• MLM – Landing mass = 652 000 lb - 576 890 lb = 75 110 lb
• LM = ATOM - Trip fuel = 775 510 lb - 198 620 lb = 576 890 lb
• On top of this calculation, for the MLM limitation we have to apply the fuel penalty - which will be burned off during the flight

Rule of thumb: to calculate fuel penalty, use the following formula: 
(MLM extra / 1000) x Y 
- where "Y" is the variable given by the question, in this case = 470

( 75 110/1 000) x 470 = 35 302 lb

Extra fuel that can be loaded is the sum of MLM extra (75 110 lb) and fuel penalty: 
75 110 lb + 35 302 lb = 110 412 lb (this value exceeds the MTOM limitation)

⇒ The most restricting value in based on MTOM: 99 490 lb
