SYLLOGISM #Part 2 # NO ( Conclusion)

Syllogism topic is very important in reasoning section of all competitive exams. If you understand the basics of syllogisms and how to draw Venn diagram. I am sure that after learning the basics you will be able to solve the 5 Questions in just two minutes.


In Part 2 we are going to solve the problems where the conclusion is based on NO.


NOTE : If you will find NO in conclusion we have to follow some rules. We need to draw two venn diagrams for this type of questions. that are basic diagram and possibility diagram.
Conclusion is true only when the condition is satisfies the both diagrams. otherwise it is False
                   

Example 1 :

STATEMENT:

1) Some A are B

2) All B are C

3) No C is D

CONCLUSION:

I) No D is A

II)  No D is B

Ans : We need to draw basic and possibility diagrams.



                             Basic         Possibility

Conclusion I)        True             False        =  False

 Conclusion II)      True             True        =  True

Answer is only conclusion II is follows       

Example 2 :

STATEMENT:

1) All Cake are Sweet

2) All Sweet are goods

3) Some Goods are best

4) No Good is Chocolate

CONCLUSION:

I) No Chocolate is Best

II) No Chocolate is Cake

III) No Chocolate is Good

Ans:



                             Basic         Possibility

Conclusion I)           True        False          =  False

Conclusion II)          True       True            =  True

Conclusion II)          True       True             =True

Answer is both II and III conclusions are True

SYLLOGISM # Part 1# SOME , ALL

Syllogism topic is very important in reasoning section of all competitive exams. If you understand the basics of syllogisms and how to draw Venn diagram. I am sure that after learning the basics you will be able to solve the 5 Questions in just two minutes.


How to solve the questions:


Step 1: Draw the Venn Diagram.


Step 2: Derive the conclusions


In the question you will have the Statements and Conclusions. By using Statements you need to draw the venn diagram and next derive the conclusions as following:


Part 1:How to draw the venn diagram for Some and ALL statements


           

Lets move to some examples. so that you will understand the concept very easily.

Example 1:

STATEMENT:

1 ) Some Apples are Mangoes

2 ) All Mangoes are Bananas

CONCLUSION:

I)    All Bananas are Mangoes

II )  All Apples are Bananas

III)  Some Apples are Bananas

IV)  Some Mangoes are Apples

Ans:

Conclusion I : False

                   II: False

                   III: True ( Blue color part)

                   IV) True ( Pink color part)

Conclusion III and IV are        

Example 2:

STATEMENT:

 1) All fish are birds

2) Some hens are fish

CONCLUSION:

I ) Some hens are birds

II)  All birds are hens

Ans:

         

Conclusion I : True ( Blue color part )

                  II: False

 Only Conclusion I Follows

Number Series for SBI PO 2018

The Number Series Tricks are very important for every competitive exams. By using the below tricks you will be able to do the number series problems very easily.


Before going to problems lets understand the Five main topics of Number Series


1) Series based on Square or Cube
2) Series based on Decimal number
3)Completely Divisible  series
4) Half Pattern series
5) Series based on Multiplication


Lets take one by one

1) Series based on Square or Cube

Example: 1 , 2, 6 , 33 , 49, 174 , ?


Ans:  1 , 2   , 6  ,  33   ,   49   , 174  ,  ?

6*6 = 36

36+174=210

2) Series based on Decimal number

Example : 12 , 6.5 , 7.5 , 12.75 , 27.50 , ?


Note : If you will find any decimal number in number series . Answer will be multiply by * 0.5 or 1.5

27.50*2.5 = 68.75+2.5 =71.25  

3)Completely Divisible  series

Example:  12  , 12  ,  18  , 45  , 180  ,   ?

Note : If the same numbers are exist in the question. Maximum answer will follows the Divisible method.

180 * 6 = 1080 

4) Half Pattern series

Example: 70     ,       40     ,       50     ,   90         ,  200   ,        ?

Note : Whenever you will find the second number is near of half of first number and third number is near of second number . Then , that series is based on  Half Pattern Series.
Whenever your series is Half pattern . as per the name it is required we have to multiply with 0.5
                        

200*2.5  = 500+25= 525

5) Series based on Multiplication:

Example : 1   , 10 ,   28 ,   91 , 370 ,    ?

Note : In the above question the difference of the 91 and 370 is huge. If any series you will find that number is suddenly increased bulk . that series is based on multiplication. in this case try to solve the question from last (from right side).

370*5 = 1850+5= 1855

Inequalities for SBI PO 2018

Today I am going to tell techniques for inequalities. After learning these tricks you will be able to answer within 10 seconds by seeing question itself.

We have to learn 3 main symbols in inequalities. That are >,< and =.

Greater than(>):

                   

Less Than(<):

                        

Equal To(=):

  

                                 

                                

Consider we can travel from open gate and we can not travel from closed gate.

Lets go to Three important main rules to solve the questions without using pen and paper.

In the above important rules. If the conclusion given with Greater than equal to(>=).Then, The statement given with the three symbols. That are >= , > , = .

As shown in the above diagram if the conclusion given with >= then the statement will travel only in >= and = . It wont travel in >.

NOTE: Same will applicable to other two important rules.

EXAMPLE 1 :

Statement :A<D>C<E>B

CONCLUSION: I) C > B - False

                                  II) A < E -False

ANS: I)C > B ( We have to travel from C to B . because gate is opened from c side. Now go to statement. C to B means C<E>B. In this case we can not travel from C to E . So Conclusion I is False )

II) A<E( We have to travel from E to A . lets go to statement  A<D>C<E. In this case

We can travel from E to C .Next C to D we can not travel . So conclusion II is also False

)
