Introduction
Analytical Reasoning skills are crucial in every field that involves Numerical Reasoning, Logic, Math , Deductions & Inductions and fields where data needs to be analysed to discern patterns within the data. Analytical Reasoning is thus defined as the ability to look at the data/information and to find patterns or rules or connection between items in the information. Analytical Reasoning questions in competitive exams include both verbal & non-verbal questions and also involve a series of diagrams and pictures.
The article Analytical Reasoning Practice Quiz 4 lists different types of Analytical Reasoning questions with solutions useful for candidates preparing for different competitive examinations like RRB .RRB ALP/Technical Exams/Junior Engineer Recruitment Exams, SSC CGL,SSC CHSL, IBPS, SBI PO, SBI Clerks, CAT and etc.
