In a mixture of 13 litres, the ratio of milk and water is 3 : 2.
In a mixture of 13 litres, the ratio of milk and water is 3 : 2. If 3 liters of this mixture is replaced by 3 liters of milk, then what will be the ratio of milk and water in the newly formed mixture?
Answer/Solution
9 : 4
Steps/Work
Given: Total quantity of mixture = 13 liters
3 litres of mixture is removed from the container – So, let's forget this altogether!
Now, you are left with only 10 litres of mixture in 3:2 ratio.
Milk in 10 litres mix = 10 x 3 = 6 litres
(2 + 3)
Water in 10 litres mix = 10 x 2 = 4 litres
(2 + 3)
We add 3 litres milk to this.
So, milk in new mix is = 6 liters + 3 litres = 9 litres
Water= 4 litres
Ratio of milk : water = 9 : 4
Correct option: D
