Costs are 41, 42, 43, 45, 46, 47, 48, 49 (excluding 44). A is prime (41, 43, 47). F = A+2. F > E. C = E-5. D is odd. G = D+3. B is even. Deduce A=41, F=43, E=42, C=37 (invalid). A=47, F=49. E must be 48. C=43. D=45, G=48 (invalid). A=43, F=45. E must be 46. C=41. D=47, G=50 (invalid). D=45, G=48. B=42. So A=43, F=45, E=46, C=41, D=45, G=48, B=42. G (48) is costlier than E (46).
