Deductions (Syllogism) - Syllogism is the most logical chapter if we talk about logical reasoning. This chapter is also known as logical deduction & inductive reasoning. If we look closely, it's like a judicial judge who gives result or conclusion on the basis of proofs and evidence. The statements of the questions act like evidence, on the basis of this evidence you present conclusions. There are multiple approaches to solve the syllogisms questions but the Venn diagram is the most preferred method used to solve the questions of syllogism. Syllogism questions can be classified into three parts that are as follows -

1. Questions related to positive conclusions

2. Questions related to possibility conclusions

3. Questions related to negative conclusions

Let’s learn to draw a Venn diagram for the different statements of syllogism.

### How to prepare syllogism?

• Understand the statement and draw the minimum overlap venn diagram.

• Check the positive conclusions directly.

• Try to eliminate the negative conclusions.

• In possibility conclusions, try to negate them and answer accordingly.

• Practice as many questions as you can to be comfortable with every type.

• Be comfortable with the trending phrases used to create confusion.
