Rules for Solving Syllogism- Logical Deduction:
Dear Friends, Here we have given the list of main rules for solving the Syllogism Problems, candidates those who are facing struggle in syllogism can use these tips to get clear idea about this topic.
Following are the main rules for solving Syllogism Problems:
1.   All+All=All
2.   All+No=No
3.   All+Some=No Conclusion
4.   Some+All=Some
5.   Some+No= Some Not
6.   Some+Some= No Conclusion
7.   No +All = Some Not(Reversed)
8.   No+Some=Some Not (Reversed)
9.   No+No=No Conclusion
10.Some Not /Some Not Reversed+Anything = No Conclusion
If You want to convert any conclusion in Possibility:
1.   If – All A are B then we can say – Some B are Not A is a Possibility
2.   If – Some B are Not A then we can say – All A are B is a Possibility
3.   If – Some A are B then we can say – All A are B is a Possibility and All B are A is a Possibility
4.   All<=> Some Not Reversed
5.   Some => All
6.   NO Conclusion = Any Possibility is true
Implications (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
