✔ 最佳答案

Let the two buckets are of 24 cubic unit volume.
Then, in the first bucket, there is 24*3/(3+1)=18 cubic unit of flour. And there is 24*1/4=6 cubic unit of sugar.
For another bucket, there is 24*5/(5+1)=20 cubic unit of flour and 24*1/6 = 4 cubic unit of sugar.
After mixing up in the large container, there is 38 cubic unit of flour and 10 cubic unit of sugar. So,
ratio of flour to sugar = 38:10=19:5
