In this post, we will discuss Reasoning Ability as it can prove to be the most scoring section of the SBI Clerk Exam 2021. Many of you are comfortable and have good command over the reasoning section. However, some candidates find this section difficult and always try to attempt the section randomly or directly with the first questions or with Seating Arrangement/ Puzzle types questions.
In order to be successful and score more in this section, you need to focus on following important key aspects -
- If you have good command over this section than always aim to attempt maximum (25 - 30) questions during SBI Clerk Exam, which will help you in scoring high and leads you to get a high score in SBI Clerk 2021 Prelims Exam.
- In the SBI Clerk exam, you should start with those topics in which you have a good command means which seem easy to you. For example – Syllogism, Inequality, Coding-Decoding, Blood Relations, Ranking, Direction Test, Alphanumeric Series, etc.
- Never start the Reasoning section with Seating Arrangement and Puzzle types questions because if you get stuck on it, you will lose your valuable time.
Reasoning topics to Prepare for SBI Clerk Prelims 2021
1. Syllogism: These questions contain two or more statements and these statements are followed by the number of conclusions. You have to find which conclusion logically follows on the basis of given statements.
Tips to solve syllogism question in the exam
(i) Read the statement carefully and choose the correct options which satisfy the given conclusion.
(ii) Try to solve questions with the Venn diagram, which is an easy method to solve syllogism questions.
- Possibility cases in Syllogism –In possibilities cases, we have to create all possibilities to find whether the given conclusion is possible or not. If it is possible and satisfies the given statement, then the given conclusion will follow otherwise conclusion will not follow.
- Re-statement is not a conclusion – The conclusion has to be different from the statement.
Note: If the statement and conclusion are the same then, the conclusion does not follow. These rules also follow in possibilities case.
- Complementary Pairs: (Either & or) – Either and or cases only take place in complementary pairs.
Conclusions: (i) Some A are B. (ii) No A are B.
From the given above conclusions, it is easy to understand that one of the given conclusions must be true, which is represented by option either (i) or (ii). These types of pairs are called complementary pairs.
‘All A are B’ & ‘Some A are not B’ are also complementary pairs.
Note: It is important to note that, in complementary pairs, one of the two conclusions is true and others will be false simultaneously.
Complimentary pairs are formed between these cases only:
(i) ALL and SOME NOT
(ii) SOME and SOME NOT
(iii) SOME and NO.
Statement: All A are B. Some B are C.
Conclusion: I. All C are A. II. Some C are not A.
Ans – Here we can make a conclusion, either I or either II follows.
2. Inequality –It is one of the easy topics for people who are slightly comfortable with elementary mathematics. These questions are rule-based i.e. certain combinations of statements lead to certain conclusions.
Inequalities Golden Rules
(i) The combination of two inequalities can be established if they have a common term.
For example –
A > B, B > C combination can be easily established as: A > B > C. Here we can make conclusion – A > C or C < A
(ii) The combination of two inequalities cannot be established if they don’t have a common term.
For example – A > B, D < C combination cannot be established. (Here the relationship between A & C cannot be established.)
(iii) Complementary Pairs: (Either & or) – Either and or cases only take place in complementary pairs. We cannot combine two elements with common elements in which no relationship is established.
Statement: A >B < C
Conclusion: I. A > C II. A < C
Here, we cannot establish a relation between A and C. We can only draw conclusion i.e. A is either greater than or equal to C or we can say A is either smaller than C.
Try to attempt 4 questions from 5 questions from this topic if the other 2 questions seem difficult in answering.
3. Coding-Decoding–In SBI Clerk Prelims Exam, it is expected that mixed letter coding types of questions can be asked in SBI Clerk exam.
Mixed letter coding type of questions, three or four complete messages are given in the coded language and the code for a particular word is asked.
(i) To analyze, such codes, any two messages bearing a common word are picked up.
(ii) The common code word will mean that word.
(iii) Proceeding similarly by picking up all possible combinations of two, the entire message can be analyzed.
4. Seating Arrangement (Circular) – In SBI Clerk exams, five questions are frequently asked from this topic. In SBI Clerk Prelims it is expected that Sitting arrangement questions can be asked in two forms –
(i) Sitting Arrangement (Circular/Square)– Normal
(ii) Sitting Arrangement – Inward-Outward
Note – Normal sitting arrangement can be easily solved if you read the questions carefully.
For circular sitting arrangement, those objects which are facing inwards to the center are favorable to us which means the LEFT-RIGHT position is same to the reference object and those objects which are facing outwards are unfavorable to us which means the LEFT-RIGHT position is opposite to reference object.
5. Linear Seating Arrangement – In linear (row) arrangement problems, we have to arrange the data linearly. The arrangement is done only one “axis” and hence, the position of people or objects assumes importance in terms of order like first position, second position, last position. In this type of arrangement, we take directions according to our left and right.
In SBI Clerk Prelims exam it is expected that Two Row arrangement questions come in SBI Clerk exam. In two-row arrangement problems, there are two groups of people or objects sits in two rows and people sitting in a first row facing North or South and vice versa.
Tips to solve ‘Seating Arrangement (Circular / Linear)' questions
- The first step is to take a quick glance at the given information and you will get an idea of the situation of the persons.
- The second step is to pick the useful information which is “definite information” and fix the place accordingly.
For g. – A is sitting second to the left of B.
- Do not pick the negative information in the first step. Negative information means – which information does not tell anything definitive but it gives an idea to eliminate a possibility. For e.g. – A is not sitting on the immediate left of B. or B is not the opposite of E.
- The left movement is called a clockwise rotation.
- The right movement is called anti-clockwise rotation.
- Persons sitting in a CIRCLE or RECTANGLE or SQUARE facing AWAY from the center:
Seated to the left = Take Anti-clockwise direction
Seated to the right = Take clockwise direction
Important note: Meaning of – and, who and adjacent in seating arrangement (Circular/Linear)
- If two information is joining by “and”, then the information is talking about the first person.
For e.g. – A is third to the left of B and second to the right of D.
Here it means – A is sitting third to the left of B and also A is sitting second to the right of D. Many students confuse here and take information as a – A is sitting third to the left of B and B is sitting second to the right of D, which is wrong.
- If two information is joining by “who”, then the information given after “who” is talking about the second person.
For e.g. – A is third to the left of B who is second to the right of D.
Here it means – A is sitting third to the left of B and B is sitting second to the right of D. Many students usually get confused here and take information as a – A is sitting third to the left of B and also A is sitting second to the right of D, which is wrong.
- Adjacent– means – next to each other not opposite to each other. A and B are adjacent to each other, which means they are an immediate neighbour of each other.
- Accuracy– Always try to attempt the questions with 100% accuracy. As you know that the negative marking system exists in the SBI Clerk exam, which is why you must ensure that you answer each question correctly. Attempting questions with accuracy will increase the chances of scoring high.
- Speed– Try to maintain a constant speed during the SBI Clerk exam otherwise you will lose your valuable time.
