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?  Choose the correct choice from the following options
A) 9 : 1	B) 9 : 2	C) 9 : 7	D) 9 : 4	E) 9 : 3
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: 9 : 4
