  6. 6. GENERAL INTELLIGENCEANALOGYAnalogy: In this type of questions the students are required to identify the previous relationand find out the best suitable relation for the other term. These questions are asked in the formof proportion where two related terms are given and the next matching missing term can beasked. The questions of the analogy can be in the form of words, numbers, letters and codedletters etc. with any relation.For Example, Cricket : Pitch :: Tennis :: ? (a) Arena (b) Course (c) Court (d) RinkAnswer: - (c) Court. Here Cricket is played at Pitch and Tennis is played at Court.CLASSIFICATIONClassification: In this type of questions the students are required to identify the item whichdoes not belong to a group. It means the other items in the group are similar with respect tocertain logic but one is different. The students can get questions on word group, number group,letter group, coded letter group and numeral pair group etc.For Examples1. (a) 36 (b) 125 (c) 144 (d) 121Answers: - (b) All except 125 are squares.SERIESSeries: It can be understood as a sequence of numerical, alphabetical and alphanumerical termswhich follows a fixed pattern. The students are required to identify the missing term or wrongterm in the series.
  7. 7. For Example1. 6, 11, 18, 27, 38, ?. (a) 49 (c) 51 (b) 50 (d) 52Answer: - (c) The series is +5, +7, +9……CODING-DECODINGCoding: Coding is a process by which certain information is written into another form ofinformation on the basis of certain principles.Decoding: Decoding is used to infer the right information from the coded information.For Example, In a certain code language, BOOK is written as 2151511. In the same languagehow PEN be written?Answer:- In the above example the letters of BOOK is coded on the basis of their position in theEnglish alphabet. The letters B=2, O = 15, K = 11. In the same way we can encode PEN as 16514.SEQUENCEThe question on this topic can be of following types;1. Ascertaining meaningful word sequence.2. Ascertaining similar numerical sequence.3. Finding a position in a sequence.For Example,Find the meaningful order of the following words in ascending order.1. Line2. Angle3. Pentagon4. Rectangle5. TriangleAnswer: - The right order for these words will be Line – Angle – Triangle – Rectangle –Pentagon. Therefore the answer is 1, 2, 5, 4, and 3.DIRECTION TESTIn this unit, the problems are generally formulated with successive follow-up of the directionsand the candidates are required to find the final direction, the final position with respect to theinitial position or the distance between the final position and initial position.On paper, we can draw the directions as;
  8. 8. (Here, N = North, NE = North-East, E = East, SE = South-East, S = South, SW = South-West,W = West, NW = North-West)Example: If a person is going to the east of his home and turning to his left after that turning tohis right. His final positionWe can draw his path as; His HomeFor Example, A starts walking towards East, turns right, again turn right, turns left, again turnsleft, turns left, again turns left. In which direction is A walking now? (a) East (b) West (c) North (d) SouthAnswer:- (b)PUZZLESThe Puzzle questions can be in the form of following types;1. Blood Relation Problems2. Height and Position Related Problems3. Cube and Blocks Related Problems4. Embedded Words & Unscrambled Words Related Problem.Examples;1. P and Q are brothers. R and S are sisters. P’s son is S’s brother. How is Q related to R? (SSC 2011)Answer: In the question P’s son is S’s brother means P is the father of S and similarly P is thefather of R because S and R are sisters. Therefore Q is the uncle of R. because Q is the father’sbrother of R.2. There are five friends - Satish, Kishore, Mohan, Anil and Rajesh. Mohan is the tallest. Satish is shorter than Kishore but taller than Rajesh. Anil is little shorter than Kishore but little taller than Satish. Who is taller than Rajesh but shorter than Anil? (SSC 2011)
  9. 9. Answer: It is given that Kishore>Satish>Rajesh and Kishore>Anil>Satish. It means the sequenceof height is Mohan>Kishore>Anil>Satish> Rajesh. Therefore, the person who is taller thanRajesh but shorter than Anil is Satish.MATHEMATICAL PUZZLESIntroduction: In this unit we will study various types of questions based on the basicmathematical and logical concepts. These types of questions are regularly asked in the SSCexams. After analyzing previous papers, it is clear that in the exam you can get 5 to 8 questionsfrom this unit.The question types1. Arrangement of correct mathematical operations.2. Filling the correct mathematical operations.3. Mathematical-Logical problemsWhen you are solving these questions you should follow basic mathematical operations in acorrect sequence. The correct sequence of solving mathematical problems is known by“BODMAS Rule” or “VBODMAS Rule”.V – Vinculum B – Brackets O – Of D – Division M – Multiplication A – AdditionS – Subtraction.For Examples1. Which interchange of signs will make the following equation correct? 25 − 5 + 32 ÷ 4 × 6 = 13. (a) − and ÷ (b) × and ÷ (c) – and + (d) × and –Answer:- (a)2. Select the correct combination of mathematical signs to replace the * signs and to balance the given equation. 5 * 5 * 3 * 4 * 64 * 4. (a) ÷×−= + (b) ×−= +÷ (c) +×−=÷ (d) ×−=÷+Answer:- (c)
  10. 10. 3. Some equations are solved on the basis of certain system on the same basis find out the correct answer for the unsolved equation. 1 × 2 × 5 = 125, 2 × 1 × 6 = 216, 3×4×3=? (a) 125 (b) 216 (c) 512 (d) 343Answer:- (d)SYLLOGISMSyllogism: The literal meaning of syllogism is ‘Conclusion’ or ‘inference’. The questions in thesyllogism are in the form of statements (premises) followed by Conclusion (proposition) and thestudents are asked to find the correct conclusion on the basis of the statements.The general form of statements and conclusions in the syllogism is; All As are Bs. Some As are Bs. No A is a B.The graphical representation of the statements1. All As are Bs.2. Some As are Bs.3. No A is a B.
  11. 11. For ExampleDirection (Q. 1 – 2): In each questions below there are two/three statements followed by twoconclusions I and II. Assuming both the statements true, you have to decide which of the twoconclusions logically follows the statements and then give your answer(a) If only conclusion I follows.(b) If only conclusion II follows.(c) If either conclusion I or conclusion II follows.(d) If neither conclusion I nor conclusion II follows.(e) If both conclusion I and conclusion II follow.1. Statements: Some pens are pencils. Some pencils are books. Conclusions: I. Some pens are books. II. All books are pens.Answer:- (d)2. Statements: All bottles are bags. All bags are buses. Conclusions: I. Some bags are bottles. II. All bags are bottles.Answer:- (a)NON-VERBALThe questions from this unit can be of following types;1. Pictorial pattern based questions.2. Embedded figure questions.3. Mirror Image questions.4. Paper Cutting problems.5. Relationship based problems.
  12. 12. For Example1. Which answer figure will complete the pattern in the question figure? (SSC 2011) Question figure: Answer figures:Answer: (D) will complete the pattern2. Which of the answer figures is exactly the mirror image of the question figure, when the mirror is held on the line MN? (SSC 2002) Question figure: (a) (b) (c) (d)Answer: (d)3. Select the answer figure in which the question figure is hidden/embedded. Question figure: (a) (b) (c) (d)Answer: (d)
  13. 13. QUANTITATIVE APTITUDEHCF & LCMSome Important conceptsFactors and Multiples: If a number m divides the number n with remainder = 0, then m is calledthe factor of n and n is called multiple of m.Highest Common Factor (HCF): The HCF is the highest common factor for two or morenumbers.For Example, if we have two numbers 30 and 20, then the factors of 30 are 1, 2, 3, 5, 6, 10, 15and 30. And the factors of 20 are 1, 2, 4, 5, 10 and 20. Here 10 is the highest common factor.Least Common Multiple (LCM): The LCM is the lowest number which is exactly divisible by thegiven two or more than two numbers. For example, if we have two numbers 20 and 30, thenthe multiples of 20 are 20, 40, 60, 80………. And the multiples of 30 are 30, 60, 90, 120………..Here 60 is the lowest number which is exactly divisible by both 20 and 30. Therefore 60 is therequired LCM. Product of two numbers = Product of their LCM and HCF For example, the LCM for 20 and 30 is 60 and HCF for 20 and 30 is 10. Here 20 × 30 = 60 × 10 = 600.Co-primes: Two numbers are co-primes if their HCF = 1.HCF and LCM of Fraction: 𝐇𝐂𝐅 𝐨𝐟 𝐧𝐮𝐦𝐞𝐫𝐚𝐭𝐨𝐫𝐬 𝐋𝐂𝐌 𝐨𝐟 𝐧𝐮𝐦𝐞𝐫𝐚𝐭𝐨𝐫𝐬HCF = 𝐋𝐂𝐌 𝐨𝐟 𝐃𝐞𝐧𝐨𝐦𝐢𝐧𝐚𝐭𝐨𝐫𝐬 and LCM = 𝐇𝐂𝐅 𝐨𝐟 𝐃𝐞𝐧𝐨𝐦𝐢𝐧𝐚𝐭𝐨𝐫𝐬For ExampleThe L.C.M. of two numbers is 189 and H.C.F. of two numbers is 9.If one of the number is 63then other number is: (a) 27 (b) 28 (c) 29 (d) 30Answer:- (a)
  14. 14. RATIO & PROPORTIONRatio: A ratio is a comparison of two numbers (quantity in the same unit). It is written as, a: b =a = a ÷ b, where a and b are two number (quantity).bIn a ratio a : b, a and b are the terms of the ratio; ‘a’ is called the antecedent and ‘b’ is called theconsequent.The word ‘antecedent’ literally means ‘that which goes before’ and the word consequentliterally means ‘that which goes after’.Compound Ratio: Compounded ratio is a product of two or more ratios.Example: Find the ratio compounded of the three ratios:2 : 3, 3 : 4 and 7 : 11 2 × 3 ×7 7Solution: the required ratio is =3 ×4 ×11 = 22 . 1 1Inverse Ratio: If a : b is a given ratio, then a ∶ b or b : a is called its inverse ratio or reciprocalratio.1. If the antecedent (a) = the consequent (b), the ratio is called the ratio of equality, such as 2 : 2.2. If the antecedent (a) > the consequent (b), the ratio is called the ratio of greater inequality, such as 3 : 2.3. If the antecedent (a) < the consequent (b), the ratio is called the ratio of less inequality, such as 2 : 3. a cProportion: A proportion expresses the equality of two ratios. e.g. b = dOr a : b = c : d or a : b :: c : d.In a proportion in the form of a : b :: c : d the first and the last terms are called the extremesand the second and the third terms or the middle terms are called as the mean terms. Whenfour quantities are in proportion, we can write it in the mathematical form as a : b :: c : d a c = d  ad = bcb
  15. 15. For Example, 2 1If Rs. 510 be divided among A, B, C in such a way that A gets 3 of what B gets and B gets 4 ofwhat C gets, then their shares are respectively : (a) Rs. 120, Rs. 240, Rs. 150 (b) Rs. 60, Rs. 90, Rs. 360 (c) Rs. 150, Rs. 300, Rs. 60 (d) None of theseAnswer:- (b)PERCENTAGEPercentage: The term “per cent” means “for every hundred”. A fraction whose denominators is100 is called a percentage and the numerator of the fraction is called the rate per cent. It isdenoted by the symbol %. x 10 1Here x % =100 . For example 10% =100 = 10 .Similarly, fraction can be changed in the form of percentage when we multiply them by 100. 1 1For Example 4 = 4 × 100 = 25%.To decrease a number by a given %: 𝟏𝟎𝟎−𝐑𝐚𝐭𝐞Multiply the numbers by the factor 𝟏𝟎𝟎To find the % increase of a number: 𝐓𝐨𝐭𝐚𝐥 𝐢𝐧𝐜𝐫𝐞𝐚𝐬𝐞 𝐅𝐢𝐧𝐚𝐥 𝐯𝐚𝐥𝐮𝐞−𝐈𝐧𝐢𝐭𝐢𝐚𝐥 𝐯𝐚𝐥𝐮𝐞% increase = × 𝟏𝟎𝟎 = × 𝟏𝟎𝟎 𝐈𝐧𝐢𝐭𝐢𝐚𝐥 𝐯𝐚𝐥𝐮𝐞 𝐈𝐧𝐢𝐭𝐢𝐚𝐥 𝐯𝐚𝐥𝐮𝐞To find the % decrease of a number: 𝐓𝐨𝐭𝐚𝐥 𝐝𝐞𝐜𝐫𝐞𝐚𝐬𝐞 𝐅𝐢𝐧𝐚𝐥 𝐯𝐚𝐥𝐮𝐞−𝐅𝐢𝐧𝐚𝐥 𝐯𝐚𝐥𝐮𝐞% decrease = × 𝟏𝟎𝟎 = × 𝟏𝟎𝟎 𝐈𝐧𝐢𝐭𝐢𝐚𝐥 𝐯𝐚𝐥𝐮𝐞 𝐈𝐧𝐢𝐭𝐢𝐚𝐥 𝐯𝐚𝐥𝐮𝐞For Example1. In an election between two candidates, 75% of the voters casted their votes, out of which 2% of the votes were declared invalid. A candidate got 9261 votes which were 75% of the total valid votes. Find the total number of votes enrolled in that election. (SSC 2003) (a) 15000 (c) 16800 (b) 16000 (d) 17000
  16. 16. Answer:- (c) Let the total enrolled votes are x. Then, Number of votes cast = 75 % of x. Validvotes = 98 % of (75 % of x) ∴ 75 % 0f [98 % of (75 % of x)] = 92612. If 50% of (x – y) = 30% of (x + y), then what percent of x is y? (a) 25 % (b) 50 % (c) 75 % (d) 100 % 50 30Answer:- (a) here 50% of (x – y) = 30% of (x + y)  100 x − y = 100 (x + y) 1 10(x – y) = 6(x + y)  10x – 6x = 6y + 10y  4x = 16y  4 x = y  25 % of x = y. 1Because4 = 25%AVERAGEAverage is defined as the sum of n different numerical values divided by n.

Acute angle triangle: It is a triangle in which all the angles are less than 90°.2. Obtuse angle triangle: It is a triangle in which one angle is greater than 90°.3. Right angle triangle: It is a triangle in which one angle is equal to 90°.4. Equilateral triangle: It is a triangle in which all the sides are equal and the all angles are equal to 60°.5. Isosceles triangle: It is a triangle in which two sides are equal and angle opposite the equal sides are also equal.6. Scalene triangle: It is a triangle in which all the sides are unequal.General Properties of Triangles:1. Sum of the length of any two sides of a triangle is always greater than the third side.2. Difference between the lengths of any two sides of a triangle is always less than the third side.3. The side opposite to the greatest angle will be the greatest similarly the side opposite to the smallest angle will be the smallest. a b c4. Sine rule in a triangle: sinA = sinB = sinC = 2R, where a, b and c are the side of a triangle and A, B and C are the corresponding angles of the side. R is the circum radius.5. Cosine rule in a triangle: a2 = b2 + c2 – 2bc cosA.6. The exterior angle is equal to the sum of two interior angles which are not adjacent to it.Important terms1. Median: A line joining the mid-point of a side of a triangle to the opposite vertex is called a median. The median divides a triangle into two parts of equal area and the point where all the medians meet is called the centroid of the triangle. The centroid divides each median in the ratio 2 : 1.2.

  33. 33. ENGLISH LANGUAGESYNONYMSSynonyms: The word comes from ancient Greek words ‘syn’ and ‘onoma’ where ‘syn’ means‘with’ and ‘onoma’ means ‘name’. Synonyms are the word which has similar meanings.Two words are said to be synonymous when they have similar meanings. The words caste andclass is synonymous because both the words have similar meaning.For Example,Q. Find the word which is synonymous to Deny. (SSC 2011) (a) Regain (b) Refuse (c) Repair (d) ReduceAnswer: The synonyms for Deny are Contradict, Refuse, Reject etc. here we have Refuse as anoption, which means the right answer is (b).Q. Find the word which is synonymous to Deposit. (a) Degrade (b) Dethrone (c) Place (d) RemovalAnswer:- (c)ANTONYMSAntonyms: The word “antonym “comes from ancient Greek words ‘anti’ and ‘onoma’ where‘anti’ means opposite and ‘onoma’ means name. The literal meaning of antonyms is theopposite name which means the word which has opposite meaning. For example; Day – Night,Long – Short, Up – Down, Small – Large, etc.For ExampleQ. Find the opposite word to Concur. (SSC 2011) (a) Disagree (c) Disarrange (b) Disappear (d) Discourage
  34. 34. Answer: The synonyms for Concur are agree, cooperate, combine etc. Therefore the antonymfor ‘agree’ is ‘disagree’. Hence right answer is (a).Q. Find the opposite word to Condensation. (a) Abridgment (c) Compression (b) Broadening (d) ConcentrationAnswer: - (b)IDIOMS AND PHRASESIdioms and phrases refer to commonly used groups of words in English. They are used inspecific situations and often used in an idiomatic, rather than a figurative sense. Idioms areoften full sentences. Phrases, however, are usually made up of a few words and are used as agrammatical unit in a sentence.For Example,1. Ram used very ugly words against his kind uncle; he threw down the gauntlet before him. (a) he abused and insulted him (b) he threw the challenge (c) he behaved as if he was a very great and important person (d) he put several conditions for negotiationAnswer: - (b)2. He always cuts both ends (a) Work for both sides (b) Inflicts injuries on others (c) Argues in support of both sides of the issue (d) Behaves dishonestlyAnswer: - (c)ONE WORD SUBSTITUTIONOne word substitution is the words that replace a group of words or sentences without creatingor changing the exact meaning of sentences.
