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.

Verbal Method

General format of sentences given in the examinations:

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.
