Water is contained in the three tanks A, B, and C.
First, after moving 1/3 of the water of A to B, 1/3 of the water remaining in A was moved to C.
Next, after moving 1/3 of the water of B to C, 1/3 of the water remaining in B was moved to A.
As a result, the volume ratio of water remaining in A, B, and C was 2 : 3 : 4.
Find the volume ratio of the water which was contained in the tank of A, B, and C at first by the least integer ratio.
