FAQs on Alligation & Mixture Video Lecture - Quantitative Aptitude (Quant) - CAT

1. What is the principle of alligation in mixtures?
Ans. The principle of alligation is a mathematical concept used to determine the ratio in which two or more ingredients at different prices must be mixed to obtain a mixture at a desired price. It involves placing the prices of the ingredients at the ends and the price of the mixture in the center, allowing for quick calculations of the required proportions.
2. How do you calculate the ratio of two mixtures using alligation?
Ans. To calculate the ratio of two mixtures using alligation, you first find the difference between the price of each mixture and the desired price. Place these differences diagonally across from each other. The ratio of the two mixtures is then determined by the inverse of these differences, allowing you to express the required mixing ratio.
3. Can alligation be used for mixtures other than liquids, such as solids or gases?
Ans. Yes, alligation can be used for mixtures of solids, liquids, or gases. The principle remains the same regardless of the state of matter; it is a method for finding the correct proportions of different substances to achieve a specific desired property, like cost or concentration.
4. What are some practical applications of alligation and mixture problems?
Ans. Alligation and mixture problems are commonly applied in various fields such as pharmacy for compounding medications, cooking for mixing ingredients at certain ratios, and finance for portfolio management in investments. These applications help in achieving desired outcomes efficiently.
5. Are there any common mistakes to avoid when solving alligation problems?
Ans. Yes, common mistakes include incorrectly placing the prices in the alligation setup, miscalculating the differences, and not correctly interpreting the ratio of the mixtures. It's essential to double-check calculations and ensure that the desired price is accurately represented in the center for correct results.
