Important Mixtures and Alligation Topics

Topic Name	Explanation
Mixture	A mixture is formed when two or more elements of any kind are mixed in a specific ratio.
Alligation	This is the concept which allows one to find out the ratio of the ingredients being mixed, and thus, find out the price of the mixture to face a certain loss or profit. This helps us to determine the mean value of the mixture.
Rule of Alligation	The rule states that the quantity of cheaper elements is directly proportional to the mean price subtracted by the cost price (CP) of the dearer (expensive) element. On the other hand, the quantity of the Dearer element is directly proportional to the value we obtain when the CP of the cheaper element is divided by the Mean Price.
Formula	The above principle is formulated as follows: (Quantity of Cheaper element/ Quantity of Dearer element) = [ (CP of Dearer – Mean Price) / (Mean Price – CP of Cheaper element) ]
