Advice is - perfectly okay questions and these days it is normal not to mention the figure directly BUT there is enough information in the question to lead you to the appropriate page in CAP697 or appendix.
Q1 says LRC procedures at FL350 gives you MRJT page 33. If you don't know the method this is explained on page 24. However briefly, ISA so TAS 429 kt. Then convert the 385 NGM into 352 NAM (as tables work in air miles). TOC mass of 61500 gives an air distance of 5313 nam - 352 = 4961 nam. Enter table looking for 4961 (lies about half way between 4954 & 4971 with equates to 59350 kg. 61500 - 59350 = 2150 kg (no further corrections needed).
Q2 mentions ALTERNATE there is only one Alternate Planning graph for MRJT on P16. So it's London to sunny Manchester all details given except track which if you measure it on EHI4 is 330(T). Now work the WC, quickest and easiest in this case use CRP5 square section and you will get a 5 kt headwind.
Now use Alternate Planning graph as shown in example with a 50,000 kg LM and you should get 1450 kg & 32 mins.
Hope that helps but should be explained in your FTOs course material.
