tank A and tank B. The volume of water in tank A and tank B is the ratio 4:3. When 0.8 liters of water is added to tank A, there is twice as much water in tank A than in tank B. When tank A is filled completely to its brim,......
11.) There is some water in two tanks, tank A and tank B. The volume of water in tank A and tank B is the ratio 4:3. When 0.8 liters of water is added to tank A, there is twice as much water in tank A than in tank B. When tank A is filled completely to its brim, it is 1/4 of tank B. How much more water is needed to fill tank B to its brim?

assuming the volumes of water are A and B
A:B = 4:3 or 3A = 4B
A+0.8 = 2B so A = 2B - 0.8
3(2B-0.8) = 4B
2B = 2.4
so B = 1.2
A = 1.6

I don't quite understand this "When tank A is filled completely to its brim, it is 1/4 of tank B." so i am not sure how much of tank B is empty

There is some water in two tanks, tank A and tank B.
The volume of water in tank A and tank B is in the ratio 4 : 3.
When 0.8 liter of water is added to tank A,
there is twice as much water in tank A than in tank B.
When tank A is filled completely to its brim, it is 1/4 of tank B.
How much more water is needed to fill tank B to its brim?
The answer is being worked out.
