Mass and balance

A twin engine aeroplane is certified for a MSTOM and a MSLM of 58 000 kg and
55 000 kg respectfully. What is the limiting take-off mass for the aeroplane?
PLTOM 61 000 kg
PLLM 54 000 kg
MZFM 36 000 kg
Operating mass 55 000 kg
Trip fuel 36 000 kg
Alternative fuel 500 kg
Final reserve 500 kg
Flight duration 3 hours
Fuel consumption 500 kg per hour

What is the maximum take-off mass given:
MSTOM 43 000 kg
MSLM 35 000 kg
PLLM 33 000 kg
MZFM 31 000 kg
DOM 19 000 kg
Total Fuel capacity 12 500 kg
Maximum Trip Fuel 9000 kg
Contingency fuel 1000 kg
Alternate fuel 500 kg

Unable to figure out a clear methodology to solve these questions, unless solution is seen. Do i need a basic table reconstruct and how should it be ?
