Concept of Mixture and Alligation

Mixture: A mixture problem typically involves two or more quantities mixed together, and we want to determine the resulting concentration, quantity, or cost.

Example: Imagine mixing two types of rice, one costing $5 per kg and the other $10 per kg. The mixture’s cost depends on the ratio in which we mix them.

Alligation: Alligation is a specific rule used to solve mixture problems, especially useful when we mix two things with known quantities or costs to achieve a certain concentration or average cost.

Alligation Method: The method uses a cross formula to find the mixing ratio between two items.
