Gear train problem

In an epicyclic gear train, the internal wheels A and B and compound wheels C and D rotate independently about axis O. The wheels E and F rotate on pins fixed to the arm G. E gears with A and C and F gears with B and D. All the wheels have the same module and the number of teeth are : TC = 28; TD = 26; TE = TF = 18. Sketch the arrangement ; 2. Find the number of teeth on A and B ; 3. If the arm G makes 100 rpm. clockwise and A is fixed, find the speed of B ; and 4. If the arm G makes 100 rpm. clockwise and wheel A makes 10 rpm. counter clockwise ; find the speed of wheel B.
