Answer 1

Answer:

In the 70-liters mixture, there is 40 liters milk and 30 liters, water.

We add, say x liters of water to the mixture, then

40:(30+x) = 5:4

160 = 150 + 5x

5x = 10, or

x = 2.

So, add 2 liters water to the original mixture to make the new milk-water ratio, 5:4.. Answer.

Check: 40:32 = 8*5 : 8*4 = 5:4. Correct.
