Container A contains 800 grams of 5% salt water, and container B contains 200 grams of 10% salt water. First take out the same weight of brine from A and B respectively, then pour the brine from A into B, and pour the brine from B into A. Now the concentration of brine in the two containers is the same. Question: How many grams of salt water are taken from A and B respectively?
甲容器有5%的盐水800克，乙容器有10%的盐水200克．先分别从甲和乙中取出相同重量的盐水，再把从甲中取出的倒入乙中，把从乙中取出的倒入甲中，现在两种容器中的盐水的浓度相同．问：分别从甲和乙中取出盐水多少克？
