In a mixture of 60 litres, the ratio of milk to water is 2:1. If this ratio is to be 1:2,then find the quantity of water to be further added.
+36916 60 litres 2:1 means 1 out of (2+1) , or 1/3 is water = 20 liters and 40 litres is milk
40 litres of milk will be 1/3 of the new mixture 2/3 will be water = 80 litres
so you will have to add 60 litrers of water to the original 20 liters
The ratio of 2: 1 for a mixture of 60 liters means:
2/3 x 60 = 40 liters of milk
1/3 x 60 = 20 liters of water
So, to get the ratio down to 1 : 2, you have to add L liters of water:
M /[W + L] = 1 / 2
40 / [20 + L] = 1 / 2
80 =20 + L
L = 60 Liters of water have to be added to 60 Liters of mixture so that you have:
20 Liters of water + 60 Liters =80 Liters of water to 40 Liters of milk, or a ratio of 1 : 2.
