Given:

Initial ratio of milk to water = 11 : 3

26 liters of milk is added, then another 13 liters of milk is added.

Final ratio of milk to water = 12 : 3

Let:

Initial quantity of milk = 11x liters

Initial quantity of water = 3x liters

26 liters + 13 liters = 39 liters

Final milk = 11x + 39

(11x + 39) : 3x = 12 : 3

(11x + 39) / 3x = 4

11x + 39 = 12x

39 = 12x - 11x

x = 39

Initial milk = 11x = 11 x 39 = 429 liters

The initial quantity of milk in the mixture was 429 liters.
