**In this post, we will discuss a few syllogism tricks to solve syllogism questions in IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams.**

Syllogism questions are word based problems from the reasoning section of IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams. There are generally 5-6 syllogism questions that are asked every time in the competitive exam. Syllogism Questions are the easiest type of questions that can be solved within few seconds by using syllogism tricks.

In our previous post, we have discussed what is a syllogism and few elements of syllogism questions. In this post, we will discuss few Syllogism tricks to solve syllogism questions

**Various types of Venn diagram to solve Syllogism Questions**

**1.**

**All A’s are B’s.**

In this type of Venn diagram, The smaller circle represents set A and the larger circle represents set B. The smaller circle A which is within the circle B, we can say that all- A’s are B. This is the basic diagram which we use to represent the statement- all A’s are B.

This is the second type of Venn diagram which is used to represent the statement all A’s are B. In this Venn diagram the circle A represents the set A. Now we can use the same circle to represent the set B. In this type, we can draw the conclusion that all -A’s are B.

The conclusion that can be taken from the above statement is that some- B’s are A.

**2.**

**No A is B.**

To represent this statement, we need to take a circle A and a circle B which are not related in any way or there is no overlapping of the circles. There is no other way in which we can represent the statement- No A is B.

The conclusion that can be taken from the above statement is- No B is A.

**3. Some A’s are B**

This is the basic diagram which can be drawn from the statement some A’s are B. We draw two circles A and B which overlap each other at a certain point, from this diagram we can conclude that some A’s are B. The overlapping section represent the statement some A’s are B.

There are other possibilities in which we can show that some A’s are B.

We draw a circle A and then draw a smaller circle B inside A. From this we can conclude that some A’s are B.

We generally assume the statement some A’s are B’s as all A’s are B.

The conclusion that can be taken from the above statement is that some B’s are A.

**4.**

**Some A’s are not B.**

The basic diagram which we use to represent this statement, we draw a circle A and then draw a circle B overlapping the circle A. The part o f the circle which doesn’t overlap represents the statement some A’s are not B.

There are more possibilities in which you can represent the statement some A’s are not B.

We draw a circle A and then draw a smaller circle B inside A. The part which doesn’t come inside the circle B, represents the statement- Some A’s are not B.

Some A’s are not B can be assumed as all the A’s are not B. So, we draw circle A and circle B away from each other as such that they don’t overlap each other.

We cannot draw any conclusion from the above statement.

**Complimentary pair of statement**

It is a set of two statements in which if one statement fails then the other statement is true.

When we toss a coin there are two possible outcomes – Head or Tail. So if the coin doesn’t show head then it will definitely show tail. Similarly, if the coin doesn’t show tails then it will definitely show head. Therefore, this is how a complimentary statement works.

There are two categories of complimentary statements in syllogisms.

**1.No A is B; Some A’s are B’s**

For one statement to be true the other statement should be false. To prove that Some A’s are B, one of the A should move out and mix be B to make the other statement true. When some A’s are B fails, No A is B becomes true.

**2. All A’s are B’s; Some A’s are not B.**

For one statement to be false, the other statement should be true that is why- All A’s are B’s, and Some A’s are B’s, forms a complimentary form of a statement.

There are two types of syllogism questions that are asked in IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams.

Either the questions are asked on conclusions or possibilities. Let’s define both the terms.

**Conclusion**– A conclusion should be definitely true in all the cases.

Example: A is the wife of B = B is the husband of A.

In the above example, we can make out that if A is the wife of B then definitely B is the husband A. This is called as a conclusion- drawing definite facts from the given statement.

**Possibility –**A possibility is true only one case. There are no definite conclusions that can be drawn from the given statement. There is always a possibility of only one statement to be true.

Example: A is the son of B = B is the Parent of A

There are two possibilities that can be drawn from the above statement.

The parent can be a mother or a father. We can not predict whether B is Female or Male, so there is a possibility of any one of the statements to be true.
