The word ‘Alligation’ literally means ‘linking’. Example 1: If 100 ml water is mixed with 1000 ml of milk, what is the ratio of the mixture solution? Solution: Using basic percentage, total solution = 1100 ml, Required Ratio (Water : milk) = = 1 : 11
Mixture problems and their solutions are presented along with their solutions. Percentages are also used to solve these types of problems. Problem 1: How many liters of 20% alcohol solution should be added to 40 liters of a 50% alcohol solution to make a 30% solution?
