Sorry i don’t know how to do a search to check if this question had been asked.
i am trying to understand the answer (graph) in the given answer by ACCA.
HC ‘s mat’l is 0.270 p + 0.270 s = 5400 and 0.5P + 0.75 s = 12000 but i can’t seem to see all these in the graph. the material becomes 20 by 20 and hrs becomes 24 by 16 why???? but if i were to follow what i thought i understand the lines on the graph will not cross each other 🙁
please help.
i printed all the questions and answers from ACCA website.
