It is known that Warehouse A is 485-35=450 tons more than Warehouse B..
Because the tonnage of grain stored in warehouse A is four times that of warehouse B.
So warehouse a is three times more than warehouse B.
Therefore, warehouse B has 450/3= 150 tons.
Warehouse A has 150*4=600 tons.
A: Warehouse A originally stored 600 tons of grain, while Warehouse B stored 150 tons of grain.
