The largest possible difference is 12x8-1x20=96-20=76, not 4x20-2x8=64, which is less than 76.

Smallest A --> 8 * 2 = 16

Largest A --> 8 * 12 = 96

Smallest B --> 20 * 1 = 20

Largest B --> 20 * 4 = 80

Difference between Largest A and Smallest B

= 96 - 20

= 76

Difference between Largest B and Smallest A

= 80 - 16

= 64

Largest possible difference = 76.
