In a 60-litre combination, divide the milk by the water in a 2:1 ratio. If the ratio is 1:2, then the amount of water to be added after that is:
A. 20 litres B. 30 litres C. 40 litres D. 60 litres
Explanation: Milk quantity = 60 x 2/3 litres = 40 litres,The amount of water in it is (60-40) litres, which equals 20 litres.1: 2 is the new ratio.Allow x litres of more water to be added.Then there's milk: water = 40/20 Plus x.40/20 Plus x = 1/2 now,80 = 20 + x,x is equal to 60.60 litres of water are need to be added.
