A and B are two cylindrical containers filled with water. The height, bottom area, and volume of the two cylindrical containers are not equal. If the water is drained out at the same speed, the water in container A can be drained in 12 minutes, and the water in container B can be drained in 16 minutes. Now at this drainage speed, the two containers A and B are drained at the same time for 6 minutes, and the height of the remaining water in the two containers is equal. What percentage of the height of cylindrical container B is equal to the height of cylindrical container A?
甲、乙两个盛满水的圆柱形容器，这两个圆柱形容器的高、底面积、体积都不相等．以某种相同的水速向外排水，12分钟可以将甲容器里的水排完，16分钟可以将乙容器里的水排完．现在以这种排水速度将甲、乙两个容器同时排水6分钟后两个容器剩余的水的高度相等．乙圆柱形容器的高相当于甲圆柱形容器高的百分之几？
