Solving Syllogism - Verbal Reasoning Problems

In syllogism reasoning problems, two statements are given, followed by two conclusions, I and II. You have to consider the statements to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, follows from the given statements.

We can solve syllogism reasoning problems with the help of Venn diagram. Using this Venn diagram we solve each and every questions and we get conclusion easily. According with statement we need to draw Venn diagram.

There are different types of statements has given one is definite case as conclusion and another is possibility case and you have to draw different Venn diagram. Before going to conclusion you have to draw a simple Venn diagram, which help you to get conclusion easily.

Syllogism short cut tricks:.
 
All DOGS are CATS


 
 
Some DOGS are CATS


 
 
No DOG is CATS


 
 
Some DOGS are not CATS


 

In each of the below questions given Two statements are followed by two conclusion which numbered 1 and 2. You have to consider the two given statements to be true even if they seem to be at variance from commonly known facts and choose the correct option about conclusions which logically follows from the two given statements.

Statements

All cows are goat
All goat are dog
Conclusions:
All cows are dog
Some cows are dog
 

 
Answer:
(e) both i or ii follows.

So 1st is true.
In pics shows that all portion of cows are dog so we can say some portion of cows for sure belongs to dog.
 
 

Either case

Statements
All cows are dogs
Some dogs are goat
No goat are rat
Conclusions:
Some rat are cows
No rat are cows


 
Answer: (c) either i or ii follows.

 
Tricks:
If subject and object are similar.
If one conclusion is positive or another conclusion is shows negative.
And, if relations between rat and cows is shows not actual or indirect.
Explanation:
Both conclusion are show that its a either case. how we know that first of all look at the subject and object both has same. One conclusion is show positive and another show that negative. See the Venn diagram that show that both conclusion has a indirect or not actual relations. This indications are enough to identify the Either case.




 

Possibility:

In syllogism possibility is a type of conclusion where you need to draw Venn diagram and according with statements and also verify its true or false.
Note : According to conclusion you have to draw possibility figure without affecting the statements.
the possibility type questions has give some time positive or negative way.
 
Statements
