To answer the first question, you must divide 100 by 8, and then multiply again by 3.
100 / 8 = 12.5
12.5 x 3 = 37.5
37.5% of the loot belongs to three of the robbers.
If two members are killed, you divide 100 by 6.
100 / 6 = 16.67
16.67 x 3 = 50
50% of the loot belongs to three of the robbers in this case.
With each two members killed, one member's share increases by 22.5%, or, with each individual member killed, one member's share increases by 11.25%. Hope this helped!
