SYLLOGISM

hello every body, today we will discus the concept of syllogs...
even i am providing some tips on syllogs, i still feels that wein diagram method is the best way to solve them.....

O.K but then why i am wasting every body's precious time??????
that's because as far as we have statement and conclusion in positive sentence we do not feel any problem in solving them..... but when words like NO, SOME NOT, is used in combination with other we get a bit confused...

so in this article i will be discussing only 3 things about syllogs...
1. NO, some not in combination.
2. Either and OR case.
3 Possibility case.

 All you need is this table to solve any question based on syllogs...


COMBINATION OF ALL, SOME,and NO...... 

1. ALL- ALL = answer can be given in  all and some.
eg. all kite is rope
     all rope is fish
conclusion = all kite is fish
                    some fish is kite 

2. ALL- NO = answer will ALWAYS be in NO type..

eg. all kite is rope
     NO rope is fish
Conclusion = all the valid conclusion for this case will be in NEGATIVE ONLY , i.e NO

3. SOME- ALL = answer only in some type.
eg. some kite is rope
     all rope is fish
here answer will be only in SOME TYPE
like = some rope is kite
          some fish is kite
          some kite is fish etc....

4. SOME- NO  = answer ONLY IN SOME NOT...
eg. SOME kite is rope
     NO rope is fish
the valid conclusion are only in SOME NOT only from one side...
like = SOME kite is NOT fish
           SOME fish is NOT ROPE 
NOTE = here we can't say that SOME fish is NOT kite

 5. NO - ALL = answer in some not from both side...
eg. NO kite is rope
     ALL rope is fish
the valid answer is in SOME NOT from both side.
like=  SOME kite is NOT rope
          SOME fish is NOT kite...


 NOTE =  look here conversion is being done from both sides.....


6. NO- SOME = answer only in SOME NOT from both side
just like above....

NOTE = major confusion happens when we have mixture of positive and negative sentence in the statement..  therefore CASE number 2, 4,5 and 6 are important............


EITHER and OR

THE most important thing about solving this is that u have to always look in to the CONCLUSION to find out the either-or case................
in every syllogs question we see one option as either this ( option A) or that( option B)

 EITHER and OR case takes place between these three complimentary pairs only provided that they share same element between them............ only when there is no relation is there for complimentary pairs
between ALL and SOME NOT
between SOME and SOME NOT
between SOME and NO.....

NOTE = no other case can have this option as correct......... 

lets solve examples... for same statement i am asking 3 question
1 if conclusion A is correct
2 if conclusion B is correct
3 if either conclusion A or B is correct
4 if neither conclusion A or B is correct
5 if both conclusion A or B is correct

 statement =  some noses are stomach
                     some fingers are chair
                     all fingers are eyes
                     no eyes are horse

Q1. conclusions. A.some eyes are chair    B. some fingers are nose

 Q 2.  A. some stomach are eyes    B. some eyes are not stomach

 Q3.   A. some chairs are finger       B. some noses are not eyes


ANS= questn 1 = option 1
         question 2 = option 2 (same elements with some - some not)
              question 3. = option 1 ( they have some - some not in them but the elements 
                                                                        are  different...      chair - fingers and noses- eyes)



LAST POSSIBILITY CASE....

just one simple line DRAW the normal wein diagram and all those relation which are not present in the diagram are the possibilties........

hope now doubts IF ANY are clear........

    1. you can say that without any doubt coz there is always SOME hidden in fish...
      some is always hidden....

  5. Directions (Q. 6-10): In each question below are given two/three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts. Give answer 1
    www.jobsadda.in
    www.jobsadda.in
    1) if only conclusion I follows.
    2) if only conclusion II follows.
    3) if either conclusion I or conclusion II follows.
    4) if neither conclusion I nor conclusion II follows.
    5) if both conclusion I and conclusion II follow.
    (Q. 6-7):
    Statements: All gliders are parachutes.
    No parachute is an airplane. All airplanes are helicopters.
    6. Conclusions:
    I. No helicopter is a glider.
    II. All parachutes being helicopters is a possibility.
    7. Conclusions:
    I. No glider is an airplane.
    II. All gliders being helicopters is a possibility.

    1. Solve by Raval's notations at glance
      Statements: All gliders are parachutes. GG - P
      No parachute is an airplane. PP / AA
      All airplanes are helicopters. AA - H
      6. Conclusions:
      I. No helicopter is a glider. HH / GG …x
      II. All parachutes being helicopters is a possibility. P / HH…x so given conclusion is true
      Ans. (2)
      7. Conclusions:
      I. No glider is an airplane. GG / AA
      II. All gliders being helicopters is a possibility. G / HH …x so given conclusion is true
      Ans. (5)

  6. Ques 6: 2 only conclusion 2 follows... Ques 7: 5 both conclusions follow.

  8. Hi Dodo! Great work!
    Well I know its not an appropriate place to post this but since there's no separate section for seating arrangement problems I'm posting it here. Could you please explain the step by step logic to solve this problem? Thanks in advance. Here it goes:
    Eight persons from different banks viz. UCO Bank, Syndicate Bank, Canara Bank,

    PNB, Dena Bank, Orientabl Bank of commerce, Indian Bank and Bank of Maharashtra

    are sitting in two parallel rows containing four people each in such a way that

    there is an equal distance between adjacent persons. In raw-1 A,B,C and D are

    seated and all of them are facing South. In row-2 P,Q,R and S are seated and all

    of them are facing north. Therefore, in the given seating arrangement each

    member seated in a raw faces another member of the other row.
    (All the information given above does not necessarily represents the order of

    seating as in the final arrangement)

    *C sits second to the right of the person from Bank of Maharashtra. R is an

    immediate neighbor of the person who faces the person from bank of Maharashtra.

    *Only one person sits between R and the person from PNB. Immediate neighbour of

    the person from PNB faces the person from Canara Bank.

    * The person from UCO Bank faces the person from Oriental Bank of Commerce. R is

    not from Oriental Bank of Commerce. P is not from PNB. P does not face the

    person from Bank of Maharashtra.

    *Q faces the person from Dena Bank. The one who faces S sits to time immediate

    left of A.

    * B does not sit at any of the extreme ends of the line. The person from Bank of

    Maharashtra does not face the person from Syndicate Bank

    1. Simply try to solve the puzzle to with the help of 2 diagram or diagram as required. Try heat and trail method in ur diagram. Put the data's in both ur diagram and as given in the puzzle. Apply some logic and write the key points like r-OBC not belongs to.
      P - pnb not blngs to

      one of ur diagram will satisfy the data automatically ....

  12. Complete rule for POSSIBILITY IN SYLLOGISM.....

    11. If - All A are B
    then we can say - Some B are Not A is a Possibility


    12. If - Some B are Not A
    then we can say - All A are B is a Possibility

    13.If - Some A are B
    then we can say - All A are B is a Possibility
    All B are A is a Possibility

    14. All  Some Not Reversed
    15. Some => All
    16.NO Conclusion = Any Possibility is true



    hai na mazedaar......
