解答

(8100 - 6000)/7% + 2000
+
(10200-6000)/7% +2000
= 94000
Assume A works 8 hours per day so B works 4 hours.So A produces 7200 toys on that day while B produces 14400.So A produces 7200/(7200+14400) = 1/3.So the anwser is 33.33%.
There might be a easier way of thinking.But I think this way is very staight forward and quick.
