SSC CHSL Tier 1 2016 General Intelligence & Reasoning Questions with Solutions

Explanation

The five individuals can be placed in five positions from left to right, numbered 1 to 5.

According to the clues: Pooja is third from the extreme right end (position 5), which means Pooja is at position 3. Vishu is second to the left of Pooja, placing Vishu at position 1. Ram is the immediate neighbour of Vishu, which places Ram at position 2. Rani is third to the right of Ram, placing Rani at position 5 (2 + 3 = 5). Vishakha is to the right of Pooja, which places Vishakha at position 4.

The final arrangement from left to right is: Position 1: Vishu Position 2: Ram Position 3: Pooja Position 4: Vishakha Position 5: Rani

This puts Pooja in the middle position.

Explanation

All four words start with the common prefix Manu. Comparing the fifth letter of each word, Manualism (ii) and Manual (iv) have the letter a, Manufacture (i) has f, and Manumission (iii) has m. Since a comes before f, and f comes before m, the words starting with Manua come first, followed by Manuf, and then Manum.

Between Manual (iv) and Manualism (ii), the shorter word Manual is a complete prefix of Manualism, meaning Manual (iv) appears before Manualism (ii).

Therefore, the alphabetical order is Manual (iv), Manualism (ii), Manufacture (i), and Manumission (iii), which yields the sequence iv, ii, i, iii.

Explanation

By comparing the letters of the given words with their numerical codes, we can establish a direct mapping for each letter:

From the word TOAST coded as 56345: T corresponds to 5 O corresponds to 6 A corresponds to 3 S corresponds to 4

From the word TRAIN coded as 59310: T corresponds to 5 R corresponds to 9 A corresponds to 3 I corresponds to 1 N corresponds to 0

To write the word TORN, we extract the codes for its constituent letters: T corresponds to 5 O corresponds to 6 R corresponds to 9 N corresponds to 0

Combining these digits in order yields the code 5690.

Explanation

The numbers in each row follow a mathematical pattern where the third number is the product of the square roots of the first two numbers.

In the first row, the first number is 25 (which is 5²) and the second number is 144 (which is 12²). Multiplying their square roots gives 5 × 12 = 60.

In the second row, the first number is 81 (which is 9²) and the second number is 225 (which is 15²). Multiplying their square roots gives 9 × 15 = 135.

Following this same logic for the third row, the first number is 49 (which is 7²) and the second number is 289 (which is 17²). Multiplying their square roots gives 7 × 17 = 119.

Explanation

According to the mathematical sign decoding:

• represents subtraction (-) x represents division (÷) represents addition (+) ÷ represents multiplication (×)

Substituting these operators into the given expression: 25 - 54 ÷ 6 + 20 × 10

Applying the BODMAS rule: First, perform the division: 54 ÷ 6 = 9

This simplifies the expression to: 25 - 9 + 20 × 10

Next, perform the multiplication: 20 × 10 = 200

This simplifies the expression to: 25 - 9 + 200

Finally, perform the addition and subtraction: 16 + 200 = 216

Explanation

The letter series can be divided into three repeating blocks of four letters each, where the repeating pattern is cdef. By placing the letters from the correct option sequentially into the gaps of the series c_e_cd_f_de_, we obtain:

c d e f c d e f c d e f

This represents a perfect repetition of the pattern cdef three times. The letters inserted into the blanks in sequential order are d, f, e, c, and f.

Explanation

Let the starting point of Arjun be at the coordinates (0, 0).

When Arjun walks 10 m east, his position becomes (10, 0).

Turning left from the east direction means he is now facing north. Walking 10 m in this direction brings his position to (10, 10).

Turning right from north means he is now facing east. Walking 25 m in this direction brings his position to (35, 10).

From here, walking 10 m towards south brings his position to (35, 0). Since he was walking south, his left is towards the east.

Finally, walking 50 m to his left (east) brings his position to (85, 0).

The straight-line distance from his original position (0, 0) to his final position (85, 0) is 85 m.

Explanation

The word HIGHLY is decoded using the row-first and column-second rule. Letter H is located in Matrix-II at row 7 and column 6, giving 76. Letter I is found in Matrix-II at row 7 and column 8, giving 78. Letter G is located in Matrix-I at row 1 and column 0, giving 10. Letter H is also located in Matrix-I at row 4 and column 4, giving 44. Letter L is located in Matrix-II at row 5 and column 7, giving 57. Finally, letter Y is located in Matrix-I at row 3 and column 2, giving 32.

Explanation

To find the relation, we can break down the statement from right to left: My father's wife is Suraj's mother. The sister of Suraj's mother is his maternal aunt. The son of his maternal aunt is his cousin.

Explanation

Anjali is female. Son of my mother refers to Anjali's brother. Only sister of the son of my mother refers to the only sister of Anjali's brother, which is Anjali herself. Daughter of the only sister means the daughter of Anjali. The girl is therefore the daughter of Anjali.

Explanation

The relationship established in the first pair is between a famous river and the country it is primarily associated with. The Ganga is the most prominent and sacred river flowing through India. Following the same pattern, the Nile is the world-famous river most significantly associated with Egypt, which is historically and geographically renowned as the gift of the Nile.

Explanation

The relationship between the first pair of letters is based on their positions in the English alphabet, where A = 1, B = 2, ..., Z = 26.

For the first letter of the pair, 6 is added to its position: R (18) + 6 = X (24)

For the second letter of the pair, 6 is subtracted from its position: M (13) - 6 = G (7)

Applying the same logic to the next pair ER: E (5) + 6 = K (11) R (18) - 6 = L (12)

This yields the letters KL.

Explanation

The relationship between the letters is based on their opposite positions in the English alphabet, where the sum of the numerical positions of opposite letter pairs is always 27.

For ET : VG Position of E is 5, and its opposite is 27 - 5 = 22, which is V. Position of T is 20, and its opposite is 27 - 20 = 7, which is G.

Applying the same logic to NO: Position of N is 14, and its opposite is 27 - 14 = 13, which is M. Position of O is 15, and its opposite is 27 - 15 = 12, which is L.

Explanation

The relationship between the first pair of numbers is established by multiplying the individual digits of the first number to get the second number.

For 97: 9 × 7 = 63

Applying the same pattern to the next number: 6 × 7 = 42

Explanation

Chennai is the capital city of the state of Tamil Nadu, making it a state capital rather than a Union Territory of India.

Explanation

The letter group STD consists entirely of consonants and does not contain any vowels.

Explanation

In the number 989, the square of the first digit 9 is 81 (9² = 81), but the last two digits are 89. This violates the pattern followed by the other numbers, where the last two digits represent the square of the first digit.

Explanation

The number 3266 is not a perfect cube, whereas the other numbers are perfect cubes of consecutive integers, specifically 12³ = 1728, 13³ = 2197, and 14³ = 2744.

Explanation

The given series represents the planets of our solar system ordered by their increasing distance from the Sun, specifically focusing on the outer planets. Starting from Jupiter, the sequential order of these Jovian planets is Jupiter, Saturn, Uranus, and Neptune.

Explanation

The series follows a pattern of increasing additions to the alphabetical positions of both letters in each term.

For the first letter of each term: T is the 20th letter. U is the 21st letter (20 + 1). W is the 23rd letter (21 + 2). Z is the 26th letter (23 + 3). Following this pattern, the next letter is obtained by adding 4 to the position of Z: 26 + 4 = 30. Cycling through the alphabet, 30 corresponds to the 4th letter, which is D.

For the second letter of each term: P is the 16th letter. Q is the 17th letter (16 + 1). S is the 19th letter (17 + 2). V is the 22nd letter (19 + 3). Following this pattern, the next letter is obtained by adding 4 to the position of V: 22 + 4 = 26, which is Z.

Combining these letters results in DZ.

Explanation

The series consists of two alternating sub-series.

The first sub-series comprises the odd-positioned terms: 1st term: RP (R = 18, P = 16) 3rd term: SQ (S = 19, Q = 17) 5th term: TR (T = 20, R = 18) In this sub-series, both the first and second letters increase by 1 letter position in each subsequent term.

The second sub-series comprises the even-positioned terms: 2nd term: DM (D = 4, M = 13) 4th term: CL (C = 3, L = 12) 6th term: ? In this sub-series, both the first and second letters decrease by 1 letter position in each subsequent term.

Applying this decreasing pattern to CL: The first letter decreases from C (3) by 1 to B (2). The second letter decreases from L (12) by 1 to K (11).

This gives the missing term as BK.

Explanation

The differences between consecutive terms in the series form the sequence of consecutive prime numbers: 1 - (-1) = 2 4 - 1 = 3 9 - 4 = 5 16 - 9 = 7

The prime numbers are 2, 3, 5, and 7. The next prime number in the sequence is 11. Adding 11 to the last term of the series gives: 16 + 11 = 27

Explanation

From the given statements: The first statement indicates a partial overlap between the set of notes and the set of coins. The second statement establishes that the set of coins and the set of cards are completely disjoint, meaning they have no common elements.

To evaluate the conclusions under definite logical deduction:

Conclusion I states that all cards can be notes. Since no direct relationship is established between cards and notes in the premises, we cannot definitely conclude that all cards are notes. In classical logical deduction, a conclusion is considered true only if it is 100% certain in all possible scenarios.

Conclusion II states that some notes are neither coins nor cards. However, it is possible to construct a valid scenario where the set of notes is entirely composed of elements that are either coins or cards, meaning no note exists outside of these two categories. Because a counter-scenario exists, this conclusion is not definitely true.

Both conclusions fail to follow definitely from the given statements.

Explanation

To find the day of the week on 1st March 2010, calculate the total number of days from 27th December 2009 to 1st March 2010.

Remaining days in December 2009: 31 - 27 = 4 days Days in January 2010: 31 days Days in February 2010: 28 days (since 2010 is not a leap year) Days in March 2010: 1 day

Total number of days = 4 + 31 + 28 + 1 = 64 days

Dividing 64 by 7 to find the number of odd days: 64 ÷ 7 = 9 weeks with a remainder of 1 odd day

Adding 1 odd day to Thursday gives Friday.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare them letter by letter from left to right. All four words share the prefix Obs. Comparing the fourth letter of each word: Obscure has c, Obsession has e, and both Obstacle and Obstruct have t. Since c comes before e, and e comes before t, the first word is Obscure (ii) and the second is Obsession (iii). For the remaining two words, we compare the fifth letter: Obstacle has a and Obstruct has r. Since a comes before r, Obstacle (i) precedes Obstruct (iv).

Explanation

The letters of the word are divided into two equal halves of 4 letters each.

First half: Each letter is replaced by its succeeding letter (+1 in alphabetical order). Second half: Each letter is replaced by its preceding letter (-1 in alphabetical order).

For the word REMINDER: R (+1) → S E (+1) → F M (+1) → N I (+1) → J N (-1) → M D (-1) → C E (-1) → D R (-1) → Q

For the word STANDARD: S (+1) → T T (+1) → U A (+1) → B N (+1) → O D (-1) → C A (-1) → Z R (-1) → Q D (-1) → C

Explanation

In each column of the grid, the sum of the number in the first row and the alphabetical position of the letter in the second row equals the alphabetical position of the letter in the third row.

For the first column: 19 + 4 (D) = 23 (W)

For the second column: 5 + 5 (E) = 10 (J)

For the third column, letting the missing number be x: x + 16 (P) = 26 (Z) x = 26 - 16 = 10

Explanation

According to the given code, the letters denote the following mathematical operations: A means + B means ÷ C means × D means -

Substituting these operations into the expression 116 B 29 C 6 A 24 D 45 gives: 116 ÷ 29 × 6 + 24 - 45

Applying the BODMAS rule: First, perform the division: 116 ÷ 29 = 4

Next, perform the multiplication: 4 × 6 = 24

Then, perform the addition and subtraction: 24 + 24 - 45 = 48 - 45 = 3

Explanation

The given letter series consists of 11 characters with 5 gaps located at the 1st, 3rd, 5th, 7th, and 9th positions: _ r _ r _ t _ r _ r t

Sequentially placing the letters from option A (t, p, p, p, p) into these gaps yields the following completed series: t r p r p t p r p r t

This resulting sequence forms a perfect palindrome, reading exactly the same both forwards and backwards: t r p r p t p r p r t

Explanation

The man starts by facing East.

A clockwise turn of 270 degrees from the East direction brings him to face North, as moving 270 degrees clockwise is equivalent to moving 90 degrees anticlockwise.

Next, taking a right turn means turning 90 degrees clockwise. Turning 90 degrees clockwise from North makes him face East again.

Finally, he turns 90 degrees anticlockwise. Turning 90 degrees anticlockwise from East brings him back to facing North.

Explanation

The word DOWN is represented by the number set 95, 79, 40, 43. Using the row-first and column-second representation rule, each letter of the word is located as follows:

The first letter D is found at the intersection of row 9 and column 5 of Matrix-II, which corresponds to 95.

The second letter O is found at the intersection of row 7 and column 9 of Matrix-II, which corresponds to 79.

The third letter W is found at the intersection of row 4 and column 0 of Matrix-I, which corresponds to 40.

The fourth letter N is found at the intersection of row 4 and column 3 of Matrix-I, which corresponds to 43.

Explanation

Nishi's grandfather and Om's father are brothers, which means they belong to the same generation of grandfathers.

Their respective children, namely Nishi's parent and Om, are first cousins.

Since Nishi is the child of Nishi's parent and Hemant is the child of Om, they are in the same generation as each other. Their parents are first cousins, which makes Nishi and Hemant second cousins. Therefore, Hemant is the cousin of Nishi.

Explanation

The analogy represents the relationship between a subject matter and the academic discipline under which it is studied. Just as the Mughals and their reign are studied under the discipline of History, rivers and their courses, origins, and landforms are studied under the discipline of Geography.

Explanation

Each letter in the first group is shifted forward by 8 positions in the alphabetical order to obtain the corresponding letter in the second group.

G is the 7th letter, and 7 + 8 = 15, which corresponds to O. J is the 10th letter, and 10 + 8 = 18, which corresponds to R. N is the 14th letter, and 14 + 8 = 22, which corresponds to V.

Explanation

The relationship between the first and second letter pairs is based on the positions of the letters in the English alphabet, where A = 1, B = 2, and so on.

For the first letter, the alphabetical position decreases by 3: W (23) - 3 = T (20)

Applying this same pattern to the next pair: T (20) - 3 = Q (17)

For the second letter, the alphabetical position increases by 2: D (4) + 2 = F (6)

Applying this same pattern to the next pair: G (7) + 2 = I (9)

This yields the letters QI.

Explanation

The relationship in the given analogy follows the pattern of x² : x³. For the first pair, the number 9 is 3², and the next number 27 is 3³. For the second pair, the number 64 is 8², so the corresponding term must be 8³ which is 512.

Explanation

Rock is a natural geological formation consisting of solid mineral matter. It does not represent a designated dwelling place or shelter for living beings, whereas the rest of the terms refer to specific habitations or shelters built or used by humans and animals.

Explanation

NTR is the odd one out because it consists entirely of consonants and does not contain any vowel.

Explanation

The number 144 is a perfect square (12² = 144), whereas the other numbers are not perfect squares.

Explanation

The number 216 is a perfect cube (6³), whereas all the other numbers are perfect squares.

Explanation

The given series represents the high-value cards in a standard deck of playing cards, arranged in descending order of their rank. The sequence begins with the highest card, Ace, followed by King and Queen. Continuing this descending hierarchy of card ranks, the next term in the sequence is Jack.

Explanation

The series consists of two independent letter patterns, one for the first letter of each term and another for the second letter.

For the first letter of each term: B, D, G, K, ... The alphabetical positions of these letters are 2, 4, 7, and 11. The difference between the consecutive terms increases progressively: 2 + 2 = 4 (D) 4 + 3 = 7 (G) 7 + 4 = 11 (K) Following this sequence, the next difference must be +5: 11 + 5 = 16, which is P.

For the second letter of each term: B, Z, W, S, ... The alphabetical positions of these letters are 28 (wrapping around), 26, 23, and 19. The difference between the consecutive terms decreases progressively: 28 - 2 = 26 (Z) 26 - 3 = 23 (W) 23 - 4 = 19 (S) Following this sequence, the next difference must be -5: 19 - 5 = 14, which is N.

Combining the first and second letters gives the term PN.

Explanation

The series follows a pattern where each term is obtained by adding 5 to the alphabetical positions of the corresponding letters in the preceding term.

For the first letter of each term, the position increases by 5: H (8) + 5 = M (13) M (13) + 5 = R (18) R (18) + 5 = W (23)

For the second letter of each term, the position also increases by 5: I (9) + 5 = N (14) N (14) + 5 = S (19) S (19) + 5 = X (24)

Combining these letters yields WX.

Explanation

The series is formed by adding consecutively increasing differences to each term. The differences between successive terms are:

130 - 80 = 50 190 - 130 = 60 260 - 190 = 70

The difference increases by 10 at each step. Following this pattern, the next difference must be 80.

The missing term is: 260 + 80 = 340

Explanation

To determine which conclusions follow, we must strictly rely on the information provided in the statements without making external assumptions.

The statements establish that toys bring joy to kids and provide them with opportunities to think and perceive the world in various ways. However, they do not mention or imply anything about a child's personality.

Conclusion I suggests that a child's personality remains underdeveloped without toys, which is an overgeneralization and is not supported by the premises.

Conclusion II claims that toys are a mandatory and undetectable part of their personality, which also introduces terms and concepts entirely absent from the statements.

Since both conclusions rely on assumptions and concepts outside the scope of the given statements, neither conclusion I nor II follows.

Explanation

The bench has five positions from left to right, which can be represented as 1, 2, 3, 4, and 5.

S is at the extreme right end, so S occupies the fifth position.

R is to the left of S, which places R in the fourth position.

For the remaining three positions, Q is sitting to the left of P and to the right of T. This means the relative arrangement of these three from left to right must be T, Q, and P.

Placing them in the first three vacant positions gives the complete sequence from left to right as T, Q, P, R, S.

Counting from the left, the first is T, the second is Q, and the third is P.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, compare them letter by letter from left to right.

All four words begin with the prefix Tem.

Comparing the fourth letters, Temerity has e, while the other three words have p. Since e comes before p in the alphabet, Temerity (i) is the first word in the sequence.

Among the remaining three words, comparing their fifth letters, Tempered (iii) and Temperature (iv) both have e, whereas Temporary (ii) has o. Since e comes before o, Temporary (ii) comes after the other two and is the last word in the sequence.

To find the order between Temperature (iv) and Tempered (iii), compare their letters after their common prefix Temper. The seventh letter of Temperature is a, and the seventh letter of Tempered is e. Since a comes before e in alphabetical order, Temperature (iv) precedes Tempered (iii).

Combining these determinations yields the alphabetical sequence i, iv, iii, ii.

Explanation

The coding pattern involves reversing the sequence of letters in the given word.

When the letters of the word DONKEY are written in reverse order, it becomes YEKNOD.

Applying the same logic to the word RAINBOW, the letters written in reverse order from last to first result in WOBNIAR.

Explanation

The pattern in each row is that the third number is obtained by multiplying the first two numbers.

For the first row: 3 × 7 = 21

For the second row: 5 × 6 = 30

Applying this pattern to the third row: 8 × 1 = 8

Explanation

By substituting the symbols with their respective mathematical operators: L denotes division (÷) S denotes multiplication (×) V denotes subtraction (-) M denotes addition (+)

The given expression is: 96 L 12 S 7 V 49 M 10

Replacing the symbols with the operators: 96 ÷ 12 × 7 - 49 + 10

Applying the BODMAS rule: First, perform the division: 96 ÷ 12 = 8

The expression becomes: 8 × 7 - 49 + 10

Next, perform the multiplication: 8 × 7 = 56

The expression becomes: 56 - 49 + 10

Finally, perform the addition and subtraction: 56 - 49 + 10 = 7 + 10 = 17
