About Mixture Problems MCQs
This topic relies on ratio reasoning and the rule of alligation. Questions ask what happens to a milk and water ratio when more water is added, in what ratio two kinds of rice or sugar at different prices must be mixed to reach a target price, and how much water to add to reduce the percentage of milk. You will also see adulterated milk problems where the water percentage changes, and replacement questions where part of a mixture is removed and topped up. Alligation lets you find the mixing ratio by comparing each price with the mean price.

Frequently asked questions
What is the rule of alligation?
The rule of alligation finds the ratio in which two ingredients at different prices must be mixed to get a mixture at a given mean price. The ratio of the cheaper to the dearer quantity equals the dearer price minus the mean price, divided by the mean price minus the cheaper price.
How do you solve milk and water ratio problems?
Find the quantity of each part from the ratio first. In 35 litres with milk and water in the ratio 4:1, there are 28 litres of milk and 7 litres of water. If 7 litres of water are added, water becomes 14 litres, so the new ratio is 28:14, or 2:1.
