1. What is the concept of alligation in mixtures?

Ans. Alligation is a mathematical technique used to determine the proportions in which two or more ingredients at different prices must be mixed to achieve a desired price for the mixture. It simplifies the process of finding the ratio of components in a mixture based on their costs or qualities.

2. How do you calculate the ratio of mixtures using alligation?

Ans. To calculate the ratio using alligation, you first write down the prices or qualities of the components. Then, find the difference between the price of each component and the price of the mixture. The ratio of the components is then determined by taking the inverse of these differences.

3. Can alligation be used for more than two mixtures?

Ans. Yes, alligation can be extended to more than two mixtures. For multiple ingredients, you can apply the alligation method by calculating the differences for each pair of components and establishing the ratios accordingly. This makes it easier to handle complex mixture problems.

4. What are some common real-life applications of mixtures and alligation?

Ans. Mixtures and alligation are commonly used in various fields such as chemistry for preparing solutions, food and beverage industries for creating recipes, pharmacology for dosage calculations, and finance for calculating average costs in investments.
