SSC Study Material for Logic Reasoning: Two premise Arguments

Dec 2, 2016 17:34 IST

    In this article, we have displayed a set of 25 questions based on the Two premise Arguments. This is made for the sake of sharpening your reasoning skills. As Students appearing in SSC CGL or CHSL face the difficulty in this chapter.

    In two premise arguments, there are two statements and several conclusions are given, i.e. 2-5 in numbers and you have to find out which conclusion is satisfying/ meeting the meaning of statements. This type of logical reasoning is the simplest among all others.

    In Logic, every categorical statement is termed as “Proposition”. The standard proposition is comprised of Quantifier, Subject, Copula and Predicate.

    Proposition=Quantifier + Subject + Copula + Predicate


    After identifying this, Statements are identified on the ground of Quantity, Quality and Distribution. After that conclusion is decided by using the following concepts.

    1. a.       Immediate Deductive Inference
    2. b.      Mediate Deductive Inference

    Important Points to Remember: -

    During deriving the logical conclusions, remember the following points.

    1. The converse of the conclusions derived.
    2. The Converse of each of the given premises.
    3. The conclusion that follows from the given premises directly in accordance with the rules of syllogism.

    Give answer

    (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;
