Three premise arguments based logical resoning for SSC Exams

Dec 5, 2016 16:55 IST

    In this article, we have displayed a set of 25 questions based on the Three 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 three 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.

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

    a.       Immediate Deductive Inference

    b.      Mediate Deductive Inference

    Important Points to Remember: -

    During deriving the logical conclusions, remember the following points.

    i.                     The converse of the conclusions derived.

    ii.                   The Converse of each of the given premises.

    iii.                  The conclusion that follows from the given premises directly in accordance with the rules of syllogism.

    Type 2: Three-Premise Arguments

    Directions: (Question 1 to 19) In each of the questions below are given three statements followed by three conclusions numbered I, II and III. You have to take the given statements to be true even if they seem to be at variance with the commonly known facts.
