FAQs on Alligation & Mixture: Removed & Replaced Video Lecture - CSAT Preparation - UPSC

1. What is the concept of alligation and mixture in mathematics?
Ans. Alligation and mixture is a mathematical concept used to solve problems related to the mixing of different ingredients with varying strengths to obtain a desired strength or quality in the mixture.
2. How is alligation method used in solving mixture problems?
Ans. The alligation method involves representing the different ingredients and their strengths on a number line. By finding the average of the ingredients' strengths and comparing it with the desired strength, the quantities of each ingredient in the mixture can be determined.
3. Can you explain the process of removing and replacing an ingredient in a mixture using alligation method?
Ans. To remove and replace an ingredient in a mixture, the alligation method can be used. The ingredient to be removed and replaced is represented on the number line along with the desired strength. By finding the average of the ingredient's strength and the desired strength, the quantities of the ingredient to be removed and replaced can be determined.
4. What are some practical applications of alligation and mixture in daily life?
Ans. Alligation and mixture concepts are widely used in various daily life scenarios. For example, in cooking, the concept is used to determine the quantities of different ingredients needed to achieve a desired taste or texture in a recipe. In chemistry, it is used to calculate the concentration of solutions by mixing different solutions with known concentrations.
5. Are there any other methods to solve mixture problems apart from alligation?
Ans. Yes, apart from the alligation method, mixture problems can also be solved using algebraic equations and the method of successive dilutions. These methods involve setting up equations based on the proportions of the ingredients and solving for the unknown quantities.
