This question is really very simple but the examiner has used lots of camouflage to confuse you. DOM + TL + Fuel = Take off Mass !

You are told the performance limited take off mass is 60400 kg and there is no performance limit at the landing airfield.

Since we know the TL =11000 and DOM = 34930 .

Then the maximum fuel that could be carried ?

That is the question ? = 60400 - (11000 + 34930) = 14470
