​

Answer 1

if the ratio of 60 litre in

so water for required for 1:2 will be

50 litres

Answer 2

Answer:60 litres

Step-by-step explanation:

As in ratio 2:1 =milk:water

Sum of ratios = 2+1=3

Total volume of the mixture = 60litres

Amount of milk = 2/3 of 60 litres = 40 litres

Amount of water = 1/3 of 60 litres = 20 litres

If the ratio has to be 1:2 then amount of the water should be double of the amount of milk. Therefore 60 litres of water should be afree to make the ratio 1:2. (20litres +60 litres = 80 litres)
