Practice Alligation Questions and Answers


Alligation is another important topic that is often asked in competitive exams like RBI Grade B, RBI Assistant, SEBI Grade A, IBPS SO, IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, LIC AAO, SSC CGL, SSC CHSL, IFSCA Grade A, etc.

Alligation is a mathematical technique used to find the average concentration of a mixture of two or more components with different strengths or concentrations. Alligation involves a simple formula and a diagrammatic representation that enables one to solve the problem quickly and efficiently. The formula involves finding the weighted average of the different components in the mixture.

For example, suppose you have two liquids with different concentrations, say a% and b%, and you want to find the concentration of a mixture of these two liquids with a specific concentration, say c%. Alligation can be used to determine the amounts of each liquid that should be mixed to obtain the desired concentration.

The Alligation formula is:

(Quantity of component A) / (Quantity of component B) = (Difference between desired concentration and component B) / (Difference between component A and component B).

The Alligation diagram is a graphical representation of the same formula, where the two components A and B are represented as two points on a line, and the desired concentration c% is marked as a point on the same line. The distances from the points A and B to the point C on the line represent the strengths or concentrations of the components.

Alligation problems are often included in competitive exams because they test a candidate's ability to analyze and solve complex problems quickly and accurately. Therefore, you must ensure that you prepare this topic well.
