Some rules to solve the problem of Syllogism for Banking/SSC/RAILWAY Logical Reasoning are as follows.
There are two ways to determine that which conclusion will follow.
Another method of solving such type of questions is by drawing Venn diagram representing the statements. However, it is important that all possible Venn diagrams show as. If a conclusion can be deduced from all the possible solutions then that conclusion is true. If the conclusion can be concluded from one of the possible Venn diagram and not from the other possible Venn diagram then that conclusion is taken as false.
Therefore, Let’s have a look at the table below to understand Syllogism more clearly
Following are the four major types of statements generally asked:

While deriving conclusions, following points should be kept in mind:
Some steps to convert a solution into the possibility are given below:
Some implementations for the solution from a single statement are given below:
Hence, Let’s have a look at the table below to understand Syllogism more clearly


Solution: Three possible diagrams is show in the above for the given statements.
Conclusion I follows from last two possible solutions, but does not follow from the first possible solution. Therefore, this conclusion is false.
Conclusion II follows from all the three possible solutions.
Therefore, conclusion II is true

Directions (1–15): In each of the questions given below are given some statements followed by some conclusions. Read all conclusions and give the answer as follows:
(a) If only conclusion I follows. (b) If only conclusion II follows. (c) If either conclusion I or II follows. (d) If neither conclusion I nor II follows.
