The ratio of milk and water in a mixture is 2 : 3 and the ratio of water to milk in another mixture is 3 : 4. If 70 litres of each type of milk is added to 100 litres of pure milk, what will be the ratio of milk and water now?

Question

perl · Answer

you can make a proportion

anonymous · Answer

2*70/5=28,3*70/5=42,3*70/7=30,4*70/7=40 so ratio of milk is 58 in 70 litres and water is 82added to pure milk is 100+58=158 milk,82 water
ratio 158:82

anonymous · Answer

is it right?

callisto · Answer

The ratio of milk to water = 2 : 3 The ratio of water to milk = 3 : 4. We have 70L of : Milk = 70 * (2/5) = 28 Water = 70 - 28 = 42 We have 70L of Milk = 70 * (3/7) = 30 Water = 70 - 30 = 40 Total milk = 28 + 30 = 58 Total water = 42 + 40 = 82 Adding 100L milk... Total milk = 58 + 100 = 158 Total water = unchanged = 82 Ratio of milk to water = 158 : 82 Good, but that's not the end. You need to simplify 158 : 82!

no i am not getting the answer its in simple ratio like 3:4

callisto · Answer

The ratio of milk to water = 2 : 3 The ratio of water to milk = 3 : 4. We have 70L of : Milk = 70 * (2/5) = 28 Water = 70 - 28 = 42 We have 70L of Milk = 70 * (4/7) = 40 Water = 70 - 40 = 30 Total milk = 28 + 40 = 68 Total water = 42 + 30 = 72 Adding 100L milk... Total milk = __ + 100 = ... Total water = unchanged = 72 Ratio of milk to water = ...?

callisto · Answer

Type B is the ratio of water to milk = 3 : 4. I was sooooo careless!! :(
