### Transcript

• 1. 1 Tips & Tricks for Analytical Reasoning Reasoning is an important section in aptitude tests and one which all students need to master necessarily. It is critical for them in order to be clear employability tests. Reasoning portion checks your thinking capability. Through this section can employer may want to check how easily & quickly you can solve real life problems. We intend to make you aware about important sections in which you can score very high if you understand its concepts & practice well. We are also sharing quick conceptual tricks on different topics which would help in increasing your speed of attempting a question correctly. All the best!

• 3. 3 Analogy In analogy based questions a particular relation is being expressed between given words. Analogy based tests generally assess a candidate’s overall knowledge, power of reasoning and ability to think concisely and accurately. This section can help you earn higher marks but for that you should learn relationships which can be- Instruments & Measurements Seismograph: Earthquake Individual & Groups Man: Crowd Study & Topics Ethnology: Human Races Worker & Tool Blacksmith: Anvil Also there exist many such relationships. You can refer a good book and learn these from there. Odd one out In these kind of questions, a set of words, names, numbers or jumbled alphabets are given and the candidates are asked to point out the one which is not a part of the set. Some examples of variety of questions which come under this section, are as follows: Type 1: 22, 33, 66, 99, 121, 279, 594 Solution: Each of the number except 279 is a multiple of 11. Therefore 279 is odd one. Type 2: Endemic, Epidemic, Niche, Rife.
• 4. 4 Solution: All the other words refer to something which is widespread, except Niche which means-a position particularly well suited & hence this is contrary. Type 3 : Which of the following four sets of letters is unlike the other three? DCKL, MNST, NMYZ, QPST (a) DCKL (b) MNST (c) NMYZ (d) QPST Solution : In MNST, the letters are in alphabetical order. In the other three, the order of the letters will be alphabetical only when the first two are interchanged. Question in this section are comparatively easier than other ones. You need to attempt questions carefully to get all attempts correct. Relationships In these tests success of a candidate depends upon the knowledge of the blood relations, some of which are summarized below to help solve these tests. Mother’s or father’s son Brother Mother or father’s daughter Sister Mother or father’s brother Uncle Mother or father’s sister Aunt Mother or father’s father Grandfather Mother or father’s mother Grandmother Son’s wife Daughter-in-Law Daughter’s husband Son-in-Law Husband or wife’s sister Sister-in-Law
• 5. 5 Husband or wife’s brother Brother-in-Law Brother’s son Nephew Brother’s daughter Niece Uncle or aunt’s son or daughter Cousin Sister’s Husband Brother-in-Law Brother’s wife Sister-in-Law Grandson’s or Granddaughter’s daughter Great grand daughter Typically the questions in this segment are like : Pointing out a group photograph, R says, “To the right of the man wearing the blue suit is my mother’s father’s son.” How is he related to R? (a) Uncle (b) Nephew (c) Niece (d) Son Answer: He is R’s mother’s brother, that is, uncle The questions in this section may be craftily worded but may not be too difficult. Hence students should try and score perfectly in these kinds of questions. Series In these kinds of questions, a series of words , alphabets or a combination is given. And then question is asked on the possible next term in the series. Despite the fact that it is extremely difficult to lay down all possible combinations of series, still if you follow few steps, you may solve a series question easily & quickly. Step 1: Do a preliminary screening of the series. If it is a simple series, you will be able to solve this easily.
• 6. 6 Step 2: If you fail in preliminary screening then determine the trend of the series. Determine whether this is increasing or decreasing or alternating. Step 3: (A) Perform this step only if a series is increasing or decreasing Use following rules: I. If rise is slow or gradual, this type of series is likely to have an additional based increase. Successive numbers have been found by adding some numbers II. If rise is very sharp initially but slows down later on, the series is likely to be formed by adding squared or cubed numbers III. If the rise of a series is throughout equally sharp, the series is likely to be multiplication based IV. If the rise is irregular and haphazard, there may be two possibilities. Either there may be a mix of two series or two different kinds of operations may be going on alternately. (The first is very likely when the increase is very irregular: the second is more likely when there is a pattern, even in the irregularity of the series.) Step 3: (B) to be performed when series is alternating If the rise is irregular and haphazard, there may be two possibilities. Either there may be a mix of two series or two different kinds of operations may be going on alternately. (The first is very likely when the increase is very irregular: the second is more likely when there is a pattern, even in the irregularity of the series.) What is the next number in the series below : 14, 49, 916, 1625, ……. Options: (a) 2027 (b) 2438 (c) 2578 (d) 2536 Answer: The nautral numbers are 1, 2, 3, 4, 5, ……. Their squares are 1, 4, 9, 16, 25, ….. Each term in the given series has been formed by pairing the squares of the natural numbers 1 and 4, 4 and 9, 9 and 16, 16 and 25, … Therefore the next term = 2536. Some series questions can be really tricky and hence a lot of practice has to go into it achieve perfection in these category of questions. Coding Decoding
• 7. 7 In these kinds of questions, certain words, symbols and set of numbers are represented as some other words , symbols , set of numbers or a combination of these. And then a question is asked for a similar set. These questions are also simpler and easy. You need to recognize the pattern present in given series. You can master this section by putting little efforts & practicing few questions on your own. In a certain code language ‘SUPERMAN’ is coded as ‘USEPMRNA ’. Then in that code ‘MANAGING ’ is codes as: a) AMNAIGGN b) AMANIGGN c) AMANIGNG d) AMAINGGN Solution : Every two letters of the word are being interchanged in order. Data Sufficiency This is also one interesting section of reasoning paper. Mastering this section is not very difficult but meanwhile may not be a cake walk too. Example 1. In which year was Rahul born ? Statements: Rahul at present is 25 years younger to his mother. Rahul's brother, who was born in 1964, is 35 years younger to his mother. a. I alone is sufficient while II alone is not sufficient b. II alone is sufficient while I alone is not sufficient c. Either I or II is sufficient d. Neither I nor II is sufficient e. Both I and II are sufficient Solution: Take statement one & try solving but alone statement 1 will not be sufficient. However statement 2 is also not sufficient alone, but taking both of the statement together question can be solved. Hence answer is e. Example 2. What will be the total weight of 10 poles, each of the same weight ? Statements: One-fourth of the weight of each pole is 5 kg. The total weight of three poles is 20 kilograms more than the total weight of two poles. a. I alone is sufficient while II alone is not sufficient b. II alone is sufficient while I alone is not sufficient c. Either I or II is sufficient d. Neither I nor II is sufficient e. Both I and II are sufficient Solution: From statement 1. W/4 = 5 therefore W=20 Kg. So total weight = 200 Kg. From statement 2. 3W= 20+ 2W, W=20. So total weight is 200 Kg.
