Simplex method
I got make 36 wardrobes, make now drawer units and make 10 desks resulting in a profit of 3380?
Explanation for making 44 wardrobes with some wastage: 25 new area of wood so 5 more wardrobes can be made because wardrobes use 5 area of wood
so 36+5=41 wardrobes can be made
No desks are made so 5 area of wood free, 1 wardrobe more can be made
41+1=42
Some wood wasa wasted in the first part so 2 more wardrobes can be made
44 wardrobes.
Boolean Algebra:
Is A implies B the same as NOT (a AND NOT b) therefore the circuit uses a NOT gate and a NAND gate?
EMV: I put drive to W, take train to V, taketube to KC.
The shortest time (no delays) was about 99.4 and the average time was 114.4?

I got the same answer as you for the simplex question yeah, though I didn't give an answer for the later parts of the question where you had to talk about waste.
A implies B = (NOT A) OR B, so I don't think you got that right.
If I can remember rightly the expression for the circuit was:
(A AND (A Implies B) AND C) Implies D
= NOT (A AND ((NOT A) OR B) AND C) OR D
= NOT ([A AND (NOT A) OR (A AND B)] AND C) OR D
= NOT ([0 OR (A AND B)] AND C) OR D
= NOT (A AND B AND C) OR D
So the circuit was two AND gates for a, b and c hooked up to a NOT gate - then all of that OR'ed with D.

Woops, I started a new thread for MEI D2 before seeing your one. Oh well.
