60 litresExplanation
Quantity of milk = ((60 x (2/3)) litres = 40 litres. Quantity of water in it = (60- 40) litres = 20 litres. New ratio = 1 : 2 Let quantity of water to be added further be x litres. Then, milk : water = 40/(20+x) Now, 40/(20+x) = ½ => 20 + x =80 => x = 60. So, Quantity of water to be added = 60 litres.Related questions
