Answer 1

Answer:

So let's try this one

Step-by-step explanation:

If the ratio of milk to water is 3: 1 then let this ratio be 3x and x

Hence total volume , 3x + x = 120 ; x= 30 liter

Volume of milk = 3x = 90l ; Volume of water = x = 30l

Now we are required to change this ratio to 1 : 3 by adding only water into it

which means volume of milk remains same .

Let new volume of water be y

90/ y = 1/3 ; y = 270 litres

Hence 240 litres of water is further added to this mixture to change this ratio to 1 : 3

Therefore Answer is 240 litres .
