22100-21644=456 Thus the line in the middle of 21644 and 22100 will be 456÷2=228. As each line adds 228, and there are 3 lines including Q, 228×3= 684 Therefore Q is 22100+684=22784.

Hi is this for P3 or Sec 3? If this is P3 it’s unsolvable cause you might need trigo / pythagoras theorem for this!

Hi, I solved it using similar triangles, but you have to prove it first. :) Hope this helps.

11u of the largest portion of the cake is 143gm, 1u would then be 13gm. The mass of the biggest portion would be 13gm × 27= 351gm. 351gm would be 13 units in the whole cake, which would make the total mass of the cake be (351÷13) × 24= 648gm.
