Syllogisms Tricks with Examples Complete Explanation [How to Solve]

Syllogisms Possibility Tricks with Examples:

Hi friends Syllogisms is one of the easy to win questions in reasoning, but we have seen so many aspirants are finding difficult in solving these questions. Usually Venn diagram method (Easy) is used to solve these but they will consume time in case of NO/Possibility conclusion cases. So here we are explaining the concept of Syllogism with some examples by using some simple rules.
First and foremost have a quick glance at the Main rules to solve Syllogism Problems…
  • All+All=All
  • All+No=No
  • All+Some=No Conclusion

  • Some+All=Some
  • Some+No= Some Not
  • Some+Some= No Conclusion

  • No +All = Some Not (Reversed)
  • No+Some=Some Not (Reversed)
  • No+No=No Conclusion
  • Some Not /Some Not Reversed +Anything = No Conclusion

If the conclusion is in “Possibility” case then these rules must be applied.
  • If All A are B then we can say - Some B are Not A is a Possibility
  • If Some B are Not A then we can say - All A are B is a Possibility
  • If Some A are B then we can say - All A are B is a Possibility All B are A is a Possibility
That is
  • All <=> Some Not Reversed
  • Some => All
  • NO Conclusion = Any Possibility is true
When it is implemented (In case of Conclusion from Single Statement)
  1. All => Some that means if All A are B then Some B are A is true.
  2. Some <=> Some that means if Some A are B then Some B are A is true.
  3. No <=> No that means if No A is B then NO B is A is true

How to use these Syllogism Rules to solve questions?

Inorder to solve Syllogism there are two types:
  1. Cross Cancellation
  2. Vertical Cancellation
Let us see about Cross Cancellation with example:
Example 1:
Statements:
  1. All Cows are Parrots
  2. All Parrots are Birds
  3. No Bird is Monkey
Conclusions:
  1. No Parrot is Monkey
  2. Some Cows being Monkey is Possibility
We know you might be able to solve it by using Venn diagram method that's good  but this method won't help or a bit tough when it comes to No or possibility Conclusions

Here is explanation
Lets take 1st conclusion, we have to make relation between Parrot and Monkey so we will take statements 2 and 3.
Syllogisms Example one Explanation
This is called Cross Cancellation , We have cancelled Bird from Bird so we have left with (ALL+NO) rule, and that leads to No Parrot is Monkey So Conclusion I is TRUE.

In second statement we have Cow and Monkey so we will need to make relation between them. For this we need to take all 3 statements.
Syllogisms Three Statements Example Explanation
Now we have left with ((All+All)+NO) that is No Cow is Monkey . We don’t have any rule to convert this statement into Possibility so second conclusion is FALSE

I think we are clear with above explanation now see about Vertical Cancellation
Example 2:
Statements:
  1. Some Mails are Messages
  2. All Updates are Messages
Conclusion:
  1. All Mails Being Update is a Possibility
  2. No Update is Mail

Lets take Conclusion “All Mails Being Update is a Possibility” that means we have to make relation between Mails and Updates
Syllogisms Vertical Cancellation method

This is called Vertical cancellation. In this case direction of adding first phrase will be reversed i.e In
Above example the conclusion will be All+Some = No Conclusion.

IF we get No Conclusion in case of Possibility then according to Rules in Possibility case will be definitely true. So Conclusion 1 follows and Conclusion 2nd Don’t.

So far we have seen how to deal with All, Some, Some Not and No now let us see about Some Not in reversed condition.

What is Some Not (Reversed)?
To explain this let’s take a Simple example
  1. No A is B
  2. All B is C

So the conclusion you get for this will be as follows
(No+All) A is C = (Some Not Reversed) A is C
Therefore
Some C are Not A.

Finally my advice is...
Use this only if there are No or Possibility conclusions by following the above rules else you can happily use Venn Diagram method (If you find this method useful though). Don't get more confused for easy topics by doing unnecessary faults.

Lastly feel free to ask us if you have any doubts....

Update:
Hi guys recently I have found one rule and some terms that are asking in tests these days which I intend to share with you guys...

"No" statement can be converted into two types
1. Some Not
2. No (interchanging Subject and Predicate)

Confused???
Let me explain this with an Example
Suppose statement is given as No Professor is Student then this statement can be valid to take as
1. Some Professor are not Student
2. No Student is Professor

cleared now.

Another update is now a days in exams they are mentioning None, Only, Almost etc instead of All, Some in both statements and conclusions so I'm listing the terms here.

All => Every, Each, Any, None, Not a single, Only
Remaining will be treated as follows
Some, Many, a few, Quite a few, Not many, Very little, Most of, Almost, Generally, Often, Frequently, Atleast
Note: As far as I know these terms are very rare for Bank Exams.

    1. Hi Sekhar,
      As you see there is No conclusion for Some+Some combination both in Venn diagram model and these Rules model but there is one condition that must satisfy the following rule
      if Statements consists of "Some" and
      conclusions consists of Some and No (with same names) then it is possible to say Either Or otherwise you can say it as No Conclusion...

    1. Hi Lalita,
      No need to get confused every method is meant to solve quickly, here you can follow any method but the thing is time consumption... Venn diagram takes a bit more time incase of No and Possibilities comparing to Syllogism Rules I mentioned. If there aren't any NO, Possibilities and you feel Venn model is easy you can use that...

    1. Hi Vinita,
      Suppose take
      No A is B
      All B are C

      Now conclusion is
      no+all = some not (A is C) this has to be reversed
      Therefore you get something like this
      some C is not A
      you have to change the places of A and C that's it....

  15. how would we apply vertical cancellation to this kind of question:

    all calenders are papers.
    some calenders are animals.

    conclusion: 1) some papers are animals 2) some animals are papers

    according to venn diagram both are true but according to vertical cancellation no conclusion should be the answer as all+some=no conclusion.
    should i reverse the phrase here as well? is there any difference in considering the order of phrases when it comes to right vertical cancellation or left vertical cancellation?

    ReplyDelete
    Replies
    1. Hi,
      I already mentioned in the above explanation USE these rules only in cases of NO and Possibilities Cases to avoid confusions.
      Anyway here in vertical cancellation as mentioned above you have to take
      Some + All = Some
      so that you will get Some Animals are Papers = 2nd conclusion
      and Some can be reversed so that
      Some animals are papers = Some papers are animals is true

  16. Hi,

    I'd like to appreciate the efforts you put in imparting such useful imformation about syllogism. I'm sure a lot of people will benefit from it.

    I have a query and i'll be grateful if you could provide the detailed explanation of the technique that you will use in solving it.

    Q: All Parrots are Flowers
    No Flower is a carrot
    All carrots are fruits

    Conclusion: Some Flowers being fruits is a possibility.

    Is the above conclusion true or false?

    I look forward to hearing from you.

    Thanks in advance.

    1. Hi, sorry for the delay reply
      By cross cancelling 2nd and 3rd you will get Some fruits are not flowers
      Don't get confused here this is a tricky one, they have asked Possibility condition.
      From above the conclusion it is clear that it must be Some Not right
      so in these type of cases if possibility is given in any one of these Some or Not
      Say for example "Some Flowers being fruits is a possibility" or "No Flowers being fruits is a possibility" then it is "True"...(Remember only incase of Possibility)
      if it is not given it it do not follows
      say "Some Flowers are fruits" this is "False"

    II. All intelligent being rich is a possibility.

    ReplyDelete
    Replies
    1. Hi Praveen,
      In first conclusion Poor and Intelligent are taken so first you have to take A and B, by cancelling Rich you will get Some poor are doctors as you see some + some = no conclusion 1st one is false.
      In 2nd conclusion Intelligent and doctors are taken if you do vertical cancellation Some + All = Some Intelligent are Rich
      by rule in possibility Some A are B => All A are B is a Possibility or All B are A is a Possibility
      so 2nd follows

      Delete

      i have the same doubt...
      Some poor are rich

      so some poor are doctor

      some poor are doctor
      Some intelligent are doctors.
      I + I - No conclusion

      First one already explained in above comments.
      2nd ques
      Some + No = Some Not
      so
      Some televisions are not mobile is correct remember ONLY SOME can be taken in both ways whereas Some Not cannot.

      3rd question
      No + No = no conclusion
      Therefore any Possibility will Follow
      So Both follows since both have Possibility in them

      Some apples are fruits + No fruit is vegetable = some apple are not vegetables as some not appears 1st conclusion will not follow

      If we take All potatoes are vegetables + No vegetable is fruits = No potato is fruit
      Therefore Neither follows.

      Q2:
      All + No = No potato is fruit => No fruit is potato 1st follows
      By converting 3rd we get Some apples are fruits (don't care about Atleast).

      so

  34. If the conclusion is in “Possibility” case then these rules must be applied.
    If All A are B then we can say - Some B are Not A is a Possibility
    If Some B are Not A then we can say - All A are B is a Possibility
    If Some A are B then we can say - All A are B is a Possibility All B are A is a Possibility
    That is
    All <=> Some Not Reversed
    Some => All
    NO Conclusion = Any Possibility is true

    As given are these the only rules for possibility cases.............?
    If there are any other please share......

    1. Hi,
      I felt Venn diagram model is tough in case of Possibilities to be frank I too got confused using this model for possibility so I preferred explain it in Rules which is posted here...
      I'm really sorry for that but this is really easy method for solving them. If you just spend some time for it in the beginning.

  42. hi Harshini,
    In example 2 you are saying that conclusion 1 is following but in the statements it is written 'all updates are messages' which mean Update is inner circle of messages. if we will follow the conclusion 1 which is all mails being update is a possiblity. Then it will result in mails as inner circle for update. which follows all mails are messages.
    I think conclusion 2 is true. Can you please clear my doubt.

    1. From 1 and 2 we get No Glider is Aeroplane + 3rd gives some not
      So 1st conclusion is not possible

      From 2nd and 3rd we get Some helicopters are not Parachute
      By applying rules
      we get All parachutes being helicopters is a possibility

    1. Hi,
      Suppose take
      No A is B
      Some B are C

      Now conclusion is
      no + some = some not (A is C) this has to be reversed
      Therefore you get something like this
      some C is not A

      is no+all and no+some ll give the same result? i got confused between these two?

    6. This is a condition in Either or case
      If Statements consists only SOME or other combinations from which answers do not occur

    9. Hi karthikeyan,
      let me start with 3rd conclusion
      for that you have to take 1 and 3 that is
      Some + All give Some Pots are Rings hence this is true
      Now 1 and 2 conclusion
      I already mentioned when there is no answer arise from given statements and conclusions have
      SOME and NO (forgot to mention SOME NOT) with same Subjects and Predicates
      then Either Or will be the answer
      so
      I and II will be either or case here

      Delete
    10. so if we have SOME and NO with same subject and predicate,
      SOME and SOME NOT with same subject and predicate
      and SOME NOT and NO with same subject and predicate, then we can conclude either or. is my observation right?

    15. Hi, lets discuss conclusion wise...
      1. for this 2nd and 3rd statements have to be taken
      All + No gives No earphones are television (It follows)

      2. First take 1 and 2 you get "Some headphones are telephones" (this is 3rd Conclusion).
      Now
      Some headphones are telephones + All earphones are telephones
      gives
      Some headphones are not television (It follows)

      4. I'm so sorry that this rule which I forgot to mention is important here... I'm updating in the above post now. Thanks to you too for reminding it to me.
      "No telephones are television" can be converted into
      "Some telephones are not television" This is a valid transmission it is True.

      Delete
    16. 2. Shall we use the conclusion which is true to find another conclusion? what is the rule for that.
      how Some headphones are telephones + All earphones are telephones
      ll give Some headphones are not television. some + all = some right.


      4. can we convert No statement into some not with same subject and predicate?

      Delete
    17. I'm really sorry it's my typing mistake I took wrong statement, here is corrected one...
      From 1 and 2 we get "Some headphones are telephones"
      Now
      Some headphones are telephones + No telephones are television gives
      Some headphones are not television


      I didn't used 3rd conclusion to solve this. I just mentioned that 3rd conclusion has arrived there itself that's all. We can't use conclusions to get answers.

      Delete
    18. Thank you for your reply....
      but i cant get u, there is no statement like Some headphones are telephones, then how can we use it?

    1. Hi Gaurav,
      Some + Some leads to No conclusion
      you have to check two conditions:
      1) if given conclusions are in possibility then it will be the answer,
      2) check if the given statements posed as answer (by interchanging)

      if these 2 are not satisfied then None follows is the answer

      first let me explain about the conclusion given.
      As conclusion deals with House and Teacher you have to take 1st and 3rd statements to get conclusion.
      so No + All gives Some Not Reversed you get Some teachers are not houses
      so that conclusion does not follows...

      Lets start with from the last.
      3. Here C and B are given so you can take 1st and 2nd statements
      as per rule Some + Some gives None so any possibility is True so it Follows.

      2. Just reverse the 2nd statement you will get it.

      1. Here D and B are given as far as I remember that As well as is a possibility case.
      In 1st conclusion there is no possibility so it do not follows.

    1. Hi Saketh,
      I have already explained this in above post anyway here it is.
      To explain this let’s take a Simple example
      No A is B
      All B is C

      So the conclusion you get for this will be as follows
      (No+All) A is C = (Some Not Reversed) A is C
      Therefore
      Some C are Not A.

      the subject and predicate will interchange their places...

    1. Hi Hema, welcome to my blog...
      If question consists of 3 statements doesn't mean you have make use of all 3 for every conclusion. You have to consider only those statements which are useful to get conclusions.
      Some times answers will be appeared only using 1 or 2 statements also.

      Well coming to your example, it is not correct as "Papers" is not given in question.
      Also 1st and 2nd conclusions do not follows.

    4. Hi Vivek, Thanks for commenting...
      1. All + No = No nights are evenings => No evenings are nights True
      2. No + All = Some day are Not noon => All Day being Noon is a Possibility
      (3&4). Some + No = Some papers are not card
      but in these cases if conclusions has Some and No with same subject and Predicates then Either or is true
      5. No + All does not give No so it is False
      6. No + No = No conclusion so False
      All the Best.

    1. Hi Hema,
      1. Take 3 and 4 statements as they mentioned Plate and Cup
      Some + Some = No answer so it do not follows

      2. You have to use 2, 3 and 4 for this but
      All + Some also does not give any answer so it is also not true.

      3. Take 1 and 2 you get All Papers are Cups => Some cups are papers

      4. Convert 1st statement All papers are bottles => Some bottles are papers

      So Only 3 and 4 follows

  76. hello mam/sir

    my name is niket.
    my doubt is how to implement your logic in this qstn as i don't know the venn diagram method.so please explain me with ur logic how to solve this.Here all the 3 names (teacher, professors,lecturer) are used together in conclusion in single statement.

    Some teachers are professors.
    Some lecturers are teachers.


    Conclusions:
    I. All teachers as well as professors being
    lecturers is a possibility.
    II. All those teachers who are lecturers are
    also professors.
    1) if only conclusion I follows.
    2) if only conclusion II follows.
    3) if either conclusion I or conclusion II follows.
    4) if neither conelusion I nor conclusion II follows.
    5) if both conclusions I and II follow.

    1. Hi Niket,
      Lets see conclusion wise

      1. From 1st Some teachers are professors there are possibilities that
      All teachers are professors
      All professors are teachers
      Similarly, from 2nd Some lecturers are teachers there is a possibility that
      All teachers are lecturers
      So from All professors are teachers + All teachers are lecturers we get
      All professors are lecturers.
      Therefore All teachers and professors are lecturers is a possibility.
      Note: All this is happened because they mentioned about POSSIBILITY here
      in 1st conclusion so it follows

      2. In 2nd conclusion they didn't gave possibility case so it is not possible to get conclusion that is why it doesn not follow.

      Tip: Some + Some => No conclusion which leads any possibility to TRUE

  77. hii mam/sir
    i am Niket.
    what i understood from your explanation is as follows.if i understood wrong let me know.


    1. From 1st Some teachers are professors we can conclude following
    All teachers being professors is a possiblity.
    All professors being teachers is a possibility
    Similarly, from 2nd Some lecturers are teachers we can conclude following
    All teachers being lecturers is a possibility.
    All lecturers being teacher is a possibility.
    So from All professors being teachers is a possibility+ All teachers being lecturers being a possibility we get
    All professors being lecturers is a possibility.(All+All=ALL)
    Therefore All teachers and professors are lecturers is a possibility.

  78. is there anyone to answer this?
    if conclucion is in possibility, and both the conclusion follows all the rule of either or,
    then will it be considered as a 'either or' case or neither 'nor case'?

    1. Hi,
      Do you have any example for this???

    2. Statement:- All A are B

      Conclusion:-
      A) Some B are A is a possibility.
      B) Some B are not A.

      Look,
      Here both the conclusion are wrong,
      both have same subject and predicate,
      first one is positive and second one is negative,
      and of course its not a case of 'All' and 'No' type.

    1. Hi,
      1. All tea are coffee cannot be reversed so it is not follows
      2. Can be is a possibility case it is also not follows
      3. All cool drinks are thumps up => some thumps up are cool drinks so it follows
      Only 3 follows which is not given here so None of these is correct
