How to Solve New Pattern Syllogisms with Examples 2017

Hello and welcome to exampundit. Here is an awesome article on How to Solve new pattern Syllogisms for SBI & IBPS PO Exam 2017. This article is written by EP’s own, Sourav!

Choose the options that indicates a combination where the third statement can be logically deduced from the first two statements and that option will be your answer.

A. No fishes breathe through lungs.
    B. All fishes have scales.
    C. Some fishes breed up stream.
    D. All whales breathe through lungs.
    E. No whales are fishes.
    F. All whales are mammals.
(b) BCD
(c) ADE
(d) DEF

RULE: In these
questions, you are asked to test the validity of syllogism…. Check from the
options only…..In options, if from 1st statement & 2nd statement, you get
the 3rd statement…. Then the respective option is the answer…. i.e. you
just need to check the set in which the 3rd statement is a
logical conclusion of the first two

(in first option) statement A suggests no F breathe through L. Next statement B
gives all F have S
Statement C suggests some F breed up ST (stream). But here statement C is not
the logical conclusion of the first two. The diagram would look like this-
 Hence eliminate the
first option. 

In second option also, “all F have S” & “some F breed up ST” do not conclude
“all W breathe through L” .Clearly no need to draw any diagram because W &
L are not present in its parent statements.

Here the 3rd option is the answer because statement E ( no W are F)
is the correct conclusion of statement A (no F breathe through L) &
statement D (all W breathe through L )

2. A. Some of my
closest friends disapprove of me.

    B. Some of my closest friends are

    C. All of my closest friends disapprove of

    D. All who disapprove of me are aardvarks.
    E. Some who disapprove of me are aardvarks.
    F. Some of my closest friends are no

(a) BCD
(b) ABD
(c) BCE
(d) ABE   

Check (in 1st option) if from statement B & statement C
we get the Statement D (some CF are A, all CF are D—- does it imply All D are
A ??? ) but here All D are not A. The Venn diagram would look like this-

D1 or D2 don’t support the conclusion that
All D are A. Hence eliminate option 1.

Now examine option 2. Draw a diagram & check; it will look like below. (ARD2
can also be drawn to include all of D). However, as we do not know which case
is true it can’t be concluded that All D are ARD.
Here the answer is option 3. We know that
the intersection of CF & ARD contains those elements in the conclusion.
Hence E follows from B & C.

3. A. All roses are fragrant.
    B. All roses are majestic.
    C. All roses are plants.

    D. All roses need air.
    E. All plants need air.
    F. All plants need water.

(a) CED
(b) ACB



In option 1, all R are P; all P need A , which surely implies all R need A. The
diagram would look like this- 

So option 1 is the answer. No need to check
other options.

NOTE :  Quite
many questions have come from this section till now and the trend is expected
to continue in Mains. The more you practice, the more you focus
, the more it will become a control on Syllog. So keep practicing the basic
syllogism terminology.
