The Simple way to solve syllogism

                     Guys, the most interesting part in our infosys pattern is syllogism. :-) I was trying to solve that using logical implication for a quite time,which was really time consuming for me. Even I couldn’t be comfort with the ven diagram method which was taught during our training period. Finally I have inferred some rules for eliminating the options after a long battle, here they are:

1.SOME+SOME can not lead to a conclusion

2.ALL+SOME or SOME+ALL or NO+ALL or ALL+ NO will lead to only a “particular “ result. That is., the conclusion must be in the form of either in SOMEor in NO,Corresponding to the premises type.

3.The third one is, If all A’s are B’s, All B’s are C’s then the conclusion never includes B. B is called middle term here. Some where in the internet I heard this Middle term.

This is simply for eliminating the options, After that you can apply your own strategy as you wish either Ven Dia or Logical Implication(of course, I do Logical implication).

Try here itself:

Type2: example

Statement : Some watches are hens. All hens are wall clocks.

Conclusions :

I. All watches are wall clocks

II. some wall clocks are hens.

Options.

a) Only I can be true always

b) Only II can be true always

c) Both I and II can be true always

d) Both I and II cannot be true always

Option b is the correct answer.

As per the rule 2, there is no way for ALL(so eliminate option I), so go for CHECKING option 2, Why I am insisting this here na, there are some possibilities for both being wrong. You Blindly go for B options UNLESS the options declare anything like 3.

As I said early it just eliminating process, for truthfulness of rest of the statements pls go for a try

Type 3

All animals are monkeys. All monkeys are reptiles.

Conclusions :

I. All monkeys are animals.

II. All animals are reptiles.

Options.

a) Only I can be true always

b) Only II can be true always

c) Both I and II can be true always

d) Both I and II cannot be true always

Option b is the right answer.

Hope This will be useful for you. If you find this as something good. Please leave a comment. Happy to here you. Thanks for reading :-)

Wis u All the Best
