The supermarket ships apples of both varieties A and B at the same time, and the total weight of A is 210 kg less than that of B. At the beginning, these two kinds of apples were sold. Type A apples were very popular, and the weight sold every day was twice that of B, which was 30 kg. A week later, the supermarket decided to cut the price of apples of type B. As a result, the sales volume of type B apples quadrupled, while the sales volume of type A remained the same. After another two weeks, both types of apples were sold out. May I ask: How many kilograms of apples A and B were originally in total?
超市同时运进甲、乙两个品种的苹果，甲比乙的总重量少210千克．一开始卖这两种苹果，甲种苹果很受欢迎，每天卖出的重量是乙的2倍多30千克．一星期后，超市决定对乙种苹果进行降价促销，结果乙种苹果的销量变为原来的4倍，甲的销量不变，这样又过了两周后两种苹果全部售完．请问：甲、乙两种苹果原来共有多少千克？
