[S3 A-Maths: Combinatorics] Kept you waiting, huh? Haha. This puzzle, in itself, can be solved by taking advantage of combinatorics. By associating pattern cycles to these numbers, it's banking on the odds that the number chains are relatively small. If they are small enough to give multiple chains of maximum length 5, then it is a stable strategy that allows the prisoners to be freed and saved. Here's a video to explain the process fully!

[P6 Whole Numbers]: William and Harry have some stamps in their albums. If William gives 12 stamps to Harry, both boys will have the same number of stamps. If Harry gives 6 stamps to William, Harry will have 1/3 as many stamps as William. How many stamps does each boy have?
[P5/6 Science: Photosynthesis/Cells]: Photosynthesis is a process through which light energy is absorbed by plants and other organisms to convert carbon dioxide, water and minerals into oxygen and energy-rich organic compounds such as sugars. It occurs most widely in plants with green pigmented (chlorophyll) leaves, though algae and certain bacteria are well-known to photosynthesise. Here is a fascinating example of one such organism.
