The warehouses A and B originally had the same amount of rice stored. Later, Warehouse A transported 60 kg, and Warehouse B deposited another 210 kg. At this time, the amount of rice stored in Warehouse B was exactly 4 times that of Warehouse A. So how many kilograms of rice were originally stored in warehouses A and B?
甲、乙两个仓库原来存米数相同．后来甲仓库运走60千克，而乙仓库又存入210千克，这时乙仓库的存米数正好是甲仓库的4倍．那么甲、乙两仓库原来存大米多少千克？
