Gear reduction question

[Gadget470]

In the attached picture, there is two ways for this to go.

I didn't count the teeth but i THINK the large are 48 Teeth, small are 16 teeth. This creates a 3:1 or 1:3 ratio depending on drive shaft.

Scenario A:
Brown is driven at 27 RPM
Brown spins Small Blue at 81 RPM [27 * 3]
Small Blue is attached to Large Blue therefore BOTH Blue spin at 81 RPM.
Large Blue spins Red at 243 RPM [81 * 3]

Final: 27:243 = 1:9

Scenario B:
Red is driven at 27 RPM
Red spins Large Blue at 9 RPM [27 / 3]
Large Blue is attached to Small Blue therefore BOTH Blue spin at 9 RPM
Small Blue spins Brown at 3 RPM [9 / 3]

Final: 27:3 = 9:1
