Tank B has x liters of water.

Tank A has 4 times as much, so Tank A has 4x liters of water.

After 30 liters of water were transferred from Tank A to Tank B:

Tank B has x + 30 liters of water.

Tank A has 4x - 30 liters of water.

Now, Tank B has 24 more liters than Tank A.

---> Tank B = 24 + Tank A

---> x + 30 = 24 + (4x - 30)

---> x + 30 = 4x - 6

---> x + 36 = 4x

---> 36 = 3x

---> 12 = x

Starting amounts:

Tank B = 12 liters

Tank A = 4 · 12 = 48 liters

Total amount: 12 liters + 48 liters = 60 liters.
