Syllogism Trick 1 |
Venn Diagram Method
- Read the statement one by one
- Draw the venn diagram of each statement
- Follow the sequence of the question while drawing
- Analyze the conclusion from the Venn diagram
- Check for other alternative solutions at the end
How To Draw The Figures
Statement
All M are P
Statement
Some M are P
Statement
Some M are not P
Statement
No A is B
Example:
Statements:
I: Some pencils are dogs
II: All dogs are pens
III: All pens are cats
Conclusions:
I: All dogs are cats
II: Some pens are pencils
III: Some pencils are cats
Options:
(a) Only I and II follows
(b) Only I and III follows
(c) Only II and III follows
(d) All follows
(e) None of these
Solution: (d)
Explanation:
Analyzing the first statement, the Venn diagram can be made as;
Now as per the second statement, all dogs are pens, we can draw the Venn diagram as:
Now as per the last statement which says that all pens are cats, we get
Conclusion 1: All dogs are cats – True
Conclusion 2: Some pens are pencils – True
Conclusion 3: Some pencils are cats – True
Hence, All Follows.
Example:
Statements:
I: All men are dogs
II: All dogs are cats
Conclusions:
I: All men are Cats
II: All cats are men
Options:
(a) If conclusion I follows
(b) If conclusion II follows
(c) If either conclusion I or II follows
(d) If neither conclusion I nor II follows
(e) If both conclusion I and II follows
Solution: (a)
Explanation:
Hence, Only I Follows.
Example:
Statements:
I: All locks are keys.
II: All keys are bats.
Conclusions:
I: Some bats are locks.
II: Some locks are keys
Options:
(a) if only conclusion I follows.
(b) if only conclusion II follows.
(c) if both conclusions I & II follow.
(d) if no conclusion follows.
Solution: (c)
Explanation:
Hence, both conclusions I & II follow.

Syllogism Trick 2 |
Verbal Method
General format of sentences given in the examinations:
All M are P | A type |
No M are P | E type |
Some M are P | I type |
Some M are not P | O type |
Following are some common rules that you must know in order to solve Syllogism based problems:
- All+ All= All
- All+ No= No
- All+ Some= No conclusion
- Some + All= Some
- Some+ No= Some Not
- Some+ Some= No conclusion
The most important are the possibility cases and you will need the below rules to attempt such type of questions:
- If All M are P then Some P are Not M is a Possibility.
- If Some P are Not M then All M are P is a Possibility.
- If Some M are P then All M are P is a Possibility and All P are M is a Possibility.
Example
Statement I: Some human is rich.
Statement II: All rich are men.
Conclusions:
I: Some human is a man.
II: All men are rich.
Options:
(a) The only Conclusion I follows
(b) Only Conclusion II follows
(c) Either conclusion I or Conclusion II follows
(d) Neither conclusion I nor Conclusion II follows
Answer: (a)
Explanation:
From the above statements it is clear that some humans are rich and all rich are man, therefore there is a possibility that some humans are man.
Example
Statement I: All pots are rings.
Statement II: All bangles are rings.
Statement III: All rings are paints.
Conclusions:
I: Some paints are pots.
II: Some bangles are paints.
Options:
(a) if conclusion I follow
(b) if conclusion II follows
(c) if either conclusion 1 or II follows
(d) if neither conclusion I nor II follows
(e) if both conclusion I and II follows
Answer: (e)
Explanation:
All pots are rings + All rings are paints = A + A = A = All pots are paints —> conversion —> Some paints are pots (I)
Hence I follows.
All bangles are rings + All rings are paints = A + A = A = All bangles are paints —> implication -> Some bangles are paints (I)
Hence II follows.
Example
Statement I: All rats are bats
Statement II: Some bats are desks
Statement III: All desks are chairs
Conclusions:
I: Some desks are rats
II: Some chair are rats
Options:
(a) if conclusion I follow
(b) if conclusion II follows
(c) if either conclusion 1 or II follows
(d) if neither conclusion I nor II follows
(e) if both conclusion I and II follows
Answer: (d)
Explanation:
All rats are bats + Some bats are desks = A + I = No conclusion. Hence I and subsequently II do not follow.
