Reasoning – Syllogism Rules Trick for IBPS PO Clerk & SBI Exams

We are bringing you a some trick to help you crack Reasoning Questions in SBI PO and IBPS PO 2016 Main Exam. This is Section A in the series in which we will cover all concepts and questions on Syllogisms asked in IBPS PO & SBI PO 2015 Mains. Also here is the complete Reasoning study Material for SBI PO Exam.

Reasoning section consists of 50 questions in SBI PO Main Exam. These questions are broadly classified into the following classes:

  • Syllogism

  • Inequality

  • Coding Decoding

  • Seating Arrangement(Linear, Circular)

  • Input-Output

  • Logical Reasoning(Course of Action)

  • Logical Reasoning(Cause&Affect)

  • Logical Reasoning(Statement&Assumption)

In this article, we are discussing the first type in a manner which is comparatively lucid. Don’t worry, the rest of the types we will cover in the upcoming articles. If you want to fully understand the techniques, you will have to pay attention to each and everything that’s been taught here.

Syllogism is a verbal reasoning type problem, which is an important topic and is frequently asked in many competitive examinations in the Reasoning Section. These types of questions contain two or more statement and these statements are followed by the number of conclusion. You have to find which conclusions logically follows from the given statements.

The best method of solving the Syllogism’s problem is through Venn Diagrams. There are few ways in which the relationship could be made.

Example Part - I


A syllogism is a kind of logical argument in which one proposition (the conclusion) is inferred from two or more others (the premises).

Premise 1: All women are mothers.
Premise 2: All mothers are caring.
Conclusion: All women are caring.

All of us, who have given or are preparing for any kind of entrance exam like CAT, SSC, MAT, XAT, SCAT and others, have come across syllogisms. Venn diagrams are used to solve syllogisms and are considered the standard way. But Alas! our exams’ time limit does not provide us with the time enough to draw the diagram, label and shade it and draw the conclusion out of it!
Then!! What to do?

Well there is not much to worry. Here are some basic tips, tricks and step by step method which will help you to solve a syllogism or at least make it somewhat easier.
  1. Shortcut rules (if Venn Diagrams are confusing you) between Statement 1 and Statement 2 in that order
 All + All = All
All + No = No
All + Some = No Conclusion
Some + All = Some
Some + Some = No Conclusion
Some + No = Some Not
No + No = No Conclusion
No + All = Some not reversed
No + Some = Some not reversed

2. You can cancel out common terms in two statements given, then on the remaining terms apply the syllogisms rules and solve. E.g. Some dogs are goats. All goats are cows.out “goats” which leaves us with Some dogs are…all are cows. Important words remaining are SOME and ALL in that order. SOME + ALL = SOME, hence conclusion is SOME dogs are cows.
3. Avoid using common knowledge as Syllogisms questions usually state unnatural statements.
