Hi Adrian, thanks! May I ask why is 1u + 200 +144? This is the part which I am confused with.

Kate (after) is 1u + 200. And when you work backwards, you have to add 144 to get Kate(at first).

A:D = 2:3 A:(B+C) = 1:2 = 2:4 Therefore, (B+C):D = 4:3 C:(B+D) = 1:3 To make the total units of B+C+D to be equal, (B+C):D = 16:12 C:(B+D) = 7:21 Therefore, B:C:D = 9:7:12 Since A:(B+C) = 1:2 and (B+C)=16 A:B:C:D = 8:9:7:12 (ans)
