Venn Diagram Questions with Solutions

In logical reasoning, Venn diagram questions ask you to choose the diagram that best represents the relationship between three or more groups, such as Doctors, Men and Fathers. This topic also covers reading information from a given diagram, for example counting people who are in one group but not another, and number-based Venn diagram problems. To choose the right diagram, compare the groups two at a time. One group may lie entirely inside another (all fathers are men), the groups may partly overlap (some men are doctors), or they may not overlap at all (cats and dogs). For questions based on a given diagram, carefully read which regions are inside or outside each shape before counting. Practise the Venn diagram questions below, each with a step-by-step solution.
