The ratio(by volume) of milk and water in a mixture is 2 : 1. If we add 12 litres of water in the mixture, then the ratio of milk and water becomes 4 : 3. What is the quantity of water in the new mixture?
The ratio(by volume) of milk and water in a mixture is 2 : 1.
After adding 12 litres of water
New ratio becomes =4:3
the ratio of milk before and after adding water is same
To equalise the mike ratio before and after , multiply 2:1 with 2
=4:2
Now water ratio is changed ,(4:3)-(4:2)
1 = 12 lit
Quantity of water in new mixture= 3×12
= 36 litres
