Important Puzzle and Syllogism questions for RRB Group D 2022 exam. Check, tips and tricks!

Syllogism

Syllogism comes under the verbal reasoning section and is frequently asked in many competitive exams. These types of questions contain two or more statements and these statements are followed by a number of conclusions. You have to find which conclusions logically follow from the given statements.

Types of Syllogism

The different types of Syllogism can be described below:

Basic Syllogism: In this type, the conclusion must be 100% true Conclusions which are 99% true are considered to be false.
Either-Or Case Syllogism: In this type, when conclusions are not 100% true but the two given conclusions are 50% true then it is followed.
Coded Syllogism: In this statement and conclusions are given in the coded form. Candidates need to decode the statement and conclusion to find the answer.
Sequential Syllogism: In this type, statements are to be given followed by the options. Candidates need to choose the set in which the third statement can be logically deduced from the first two statements.

Tips & Tricks to solve the Syllogism

The best method of solving the Syllogism problem is through Venn Diagrams. There are four ways in which the relationship could be made.

Category 1

All A are B – Means the whole circle representing A lies within the circle representing B.

Here we can also make a conclusion: Some B are A. Some A are B.

For example: All boys are men.

Here we can also make a conclusion: Some men are boys. Some boys are men.

All apples are fruits.

Here we can also make a conclusion: Some fruits are apples. Some apples are fruits.

Category 2

No A is B – means that circles representing A and B does not intersect at all.

For example : No ball is bat.

No door is wall.

Category 3

Some A are B

Means that some part of the circle represented by A is within the circle represented by B.

This type of (category 3) statement gives the following conclusions:

(i) Some A are B also indicates that - Some A are not B

(ii) Some A are B also indicates that – All A are B.

(iii) Some A are B also indicates that – All B are A.

(iv) Some A are B also indicates that – All A are B and All B are A.

For e.g.: Some mobiles are phones.

(i) Category 4.

Some A are not B

This means that some portion of circle A has no intersection with circle B while the remaining portion of circle A is uncertain whether this portion touches B or not.

(i) Some A are not B also indicates that – Some A are B.

(ii) Some A are not B also indicates that – No A is B.

Puzzles

Logical Reasoning Puzzles require you to analyze the given piece of information, pick the information that is important and leave out the information that is not required in solving the given set of questions. Reasoning puzzles are mostly based on blood relations, arrangements, inequalities, etc. Sometimes, the questions test your lateral thinking and may not require any deduction or analysis.

Tips & Tricks to solve the Puzzles:

Step 1: Take a basic look at the question, and try to deduce the theme of the question

Step 2: Try to segregate the direct information from the non-direct information.

Step 3: Start solving the question with the relevant information with no negative outcome.

Step 4: After dealing with the relevant data, try to fit in data with the Secondary Information that goes according to the direct information.

Step 5: Lastly, try to fill up the negative data (Negative data does not inform us anything exactly but it gives us a chance to eliminate a possibility) to solve the remaining part of the puzzle.

Combine all the information together, to get the final results.

Note: Most of the puzzles are tricky therefore read each word with utmost care.
