Let milk be z liters.

So, water is z+50.

z + z + 50 = 350

2z = 300

z = 150

So, water and milk are 200 liters and 50 liters respectively.

Thus, the ratio of milk and water is 3:4 respectively in the mixture.

[150 - (3/7) *y + 40]: [200 - (4/7) *y] = 1:1

[190 - (3/7) *y]: [200 - (4/7) *y] = 1:1

190 - (3/7) *y = 200 - (4/7) *y

10 = (1/7) *y

y = 70.
