Dear Sir
I really enjoy your lectures, as the exam is approaching, I forgot what I’ve learned.
Could you please explain to me how do I get the answers of square metres of M1/ unit for P4, P6, C3 and C5? This paper is very hard.
Many thanks

Because material is costing $20 per sq m, it means that each unit of P4 is using 15/20 = 0.75 sq m’s; each unit of P6 is using 10/20 = 0.5 sq m’s, each unit of C3 is using 5/20 = 0.25 sq m’s, and each unit of C5 is using 10/20 = 0.5 sq m’s.
