  4. CONCEPTS: Mixture: Mixing of two or more than two type of quantities gives us a mixture. Quantities of these elements can be expressed as percentage or ratio or fraction. Alligation: It is the rule that enables us to find the ratio in which two or more ingredients at the given price must be mixed to produce a mixture of desired price

  5. ALLIGATION RULE: When two elements are mixed to make a mixture and one of the elements is cheaper and other one is costlier then, Quantity of Cheaper Quantity of Costlier CP of Costlier-Mean Price Mean Price -(P of Cheaper

  6. LAYOUT: CP of Cheaper CP of Costlier Mean Price M -C
