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

Explanation

The given series represents the countries of the world ranked in descending order of their total population. China is the most populous country in the world, followed by India as the second most populous, the United States of America as the third, and Indonesia as the fourth. This makes India the correct term to complete the sequence.

Explanation

The given sequence alternates between a number and its square.

The first, third, and fifth terms form an arithmetic progression of even numbers starting from 20: 20, 22, 24

The second, fourth, and sixth terms are the squares of these numbers: 20² = 400 22² = 484 24² = 576

Following this pattern, the seventh term is the next even number in the first sequence, which is obtained by adding 2 to 24, resulting in 26.

Explanation

Neither conclusion follows from the given statements because both introduce external assumptions and details that are not directly supported by the premises. Statement I merely points out the widespread interest in pursuing journalism, blog writing, book writing, and column writing, while Statement II establishes that reading is necessary to write better.

Conclusion I states that reading should include all kinds of styles because journalism has many facets. The given statements do not mention anything about what specific styles of reading are required, making this an unsupported generalization.

Conclusion II asserts that reading must be thorough and absorbing, and that recording observations is necessary. These details and requirements are entirely absent from the statements, meaning this conclusion cannot be logically derived. Therefore, neither conclusion follows.

Explanation

The series progresses by adding increasing increments to the alphabetical positions of the letters in each term.

For the first letter of each term: Q (17) + 5 = V (22) V (22) + 6 = B (28, which is 2 in a 26-letter cycle) B (2) + 7 = I (9)

For the second letter of each term: R (18) + 5 = W (23) W (23) + 6 = C (29, which is 3 in a 26-letter cycle) C (3) + 7 = J (10)

This pattern yields the next term as IJ.

Explanation

Each letter in the series is obtained by adding 4 to the alphabetical position of the preceding letter.

The positional values of the given letters in the English alphabet are: I = 9 M = 13 U = 21 Y = 25

Following the pattern of adding 4 to the position of the previous letter: 13 + 4 = 17

The letter at the 17th position is Q.

Continuing the pattern, 17 + 4 = 21, which is U.

Explanation

Since there are six people sitting in a row, we can represent their positions from left to right as 1, 2, 3, 4, 5, and 6.

Riya and Anuradha are sitting at the extreme ends, meaning they must occupy positions 1 and 6. Because Zeeshan is sitting to the immediate right of Riya, Riya must be at the left end, which is position 1. If Riya were at position 6, no one could sit to her right. Consequently, Zeeshan occupies position 2, and Anuradha occupies position 6 at the right end.

To find who is sitting fourth to the right of Zeeshan, we count four positions to the right starting from position 2. The first to the right of Zeeshan is position 3, the second is position 4, the third is position 5, and the fourth is position 6. Since Anuradha is at position 6, she is sitting fourth to the right of Zeeshan.

Explanation

To arrange the words in alphabetical order as they appear in a dictionary, we compare their letters from left to right.

All four words begin with the letter A.

Comparing the second letters of each word: Abrogate has the second letter b. Academic has the second letter c. Adorable has the second letter d. Ameliorate has the second letter m.

Arranging these second letters in alphabetical order gives b, c, d, and then m. This corresponds to the sequence ii, iv, iii, i.

Explanation

The coding pattern involves dividing the word into two equal halves and swapping their positions.

For the eight-letter word NATIONAL, the first half is NATI and the second half is ONAL. Swapping these halves gives the code ONALNATI.

Applying the same logic to the six-letter word ZENITH, the first half is ZEN and the second half is ITH. Swapping these halves yields the code ITHZEN.

Explanation

The pattern in each row of the matrix is determined by taking the square root of the first number and adding it to the second number to obtain the third number.

√First Number + Second Number = Third Number

Applying this relation to the first row: √529 + 7 = 23 + 7 = 30

Applying this relation to the second row: √81 + 9 = 9 + 9 = 18

Applying this relation to the third row to find the missing number: √289 + 7 = 17 + 7 = 24

Explanation

Substituting the respective mathematical operators in place of the letters: V represents - M represents + L represents ÷ S represents ×

The given expression is: 9 - 11 + 84 ÷ 12 × 6

Applying the BODMAS rule:

First, perform the division: 84 ÷ 12 = 7 The expression becomes: 9 - 11 + 7 × 6

Next, perform the multiplication: 7 × 6 = 42 The expression becomes: 9 - 11 + 42

Finally, perform the addition and subtraction: 9 + 42 - 11 = 51 - 11 = 40

Explanation

By sequentially placing the letters from the option dcdd into the gaps of the given series cd_de_dd_ecdd_e, the complete sequence becomes cdddecdddecddde.

This reveals a repeating pattern of the five-letter group cddde, which is repeated three times: cddde / cddde / cddde. This completes the series logically.

Explanation

Let the starting point be the origin (0, 0) on a standard two-dimensional plane, where the positive x-axis represents East, the negative x-axis represents West, the positive y-axis represents North, and the negative y-axis represents South.

First, Raju cycles 6 km East, bringing his position to (6, 0).

Next, turning right while facing East means turning South. Moving 8 km South changes his coordinates to (6, -8).

Finally, turning left while facing South means turning East again. Moving 16 km East increases his x-coordinate by 16, bringing his final position to (22, -8).

Comparing his final position (22, -8) to the starting position (0, 0), the x-coordinate is positive (East) and the y-coordinate is negative (South). Therefore, Raju is in the South-East direction relative to his original position.

Explanation

The matrix coding format specifies that each letter is represented first by its row number and then by its column number. To verify the representation of the word SIGN:

For the letter S, the coordinates 89 locate the element in the 8th row and 9th column of Matrix-II, which is S. For the letter I, the coordinates 11 locate the element in the 1st row and 1st column of Matrix-I, which is I. For the letter G, the coordinates 23 locate the element in the 2nd row and 3rd column of Matrix-I, which is G. For the letter N, the coordinates 44 locate the element in the 4th row and 4th column of Matrix-I, which is N.

These coordinates match the spelling of SIGN sequentially.

Explanation

Sangeeta's husband's brother-in-law refers to either Sangeeta's brother or Sangeeta's sister's husband.

In both scenarios, the daughter of Sangeeta's brother or Sangeeta's sister's husband is Sangeeta's niece.

Explanation

This analogy is based on collective nouns. A group of sheep is collectively referred to as a flock. In the same manner, a group of grapes is collectively referred to as a bunch.

Explanation

The relationship is based on adding 5 to the alphabetical position of each letter in the cluster.

The alphabetical positions of the first group of letters are: H = 8 E = 5 K = 11

Adding 5 to each position: 8 + 5 = 13 (M) 5 + 5 = 10 (J) 11 + 5 = 16 (P)

This corresponds to the letter-cluster MJP.

Applying the same logic of shifting each letter forward by 5 positions to the group NKQ: N = 14 K = 11 Q = 17

Adding 5 to each position: 14 + 5 = 19 (S) 11 + 5 = 16 (P) 17 + 5 = 22 (V)

This yields the letter-cluster SPV.

Explanation

The letter transition follows a specific pattern of alphabetical shifts:

First letter: O - 2 = M Second letter: P + 1 = Q Third letter: Q - 2 = O

Applying the same pattern to the second group of letters:

First letter: V - 2 = T Second letter: W + 1 = X Third letter: X - 2 = V

Explanation

The pattern in the analogy is based on swapping the base and the exponent of the prime factorization:

8 = 2³ 9 = 3²

Applying the same logic to the next set:

25 = 5² ? = 2⁵ = 32

Explanation

Cub is a singular noun that refers specifically to the young offspring of certain carnivorous mammals, such as bears, foxes, lions, and tigers. It denotes an individual young animal rather than a collective group of entities.

Explanation

The pair DV consists of the letters D, which is the 4th letter from the beginning of the alphabet, and V, which is the 22nd letter. In standard opposite-letter pairing where the sum of alphabetical positions is 27, the opposite letter to D is W. Since the sum of positions for D and V is 26, they do not form an opposite-letter pair.

Explanation

The number 2746 is not a perfect cube. The other numbers are perfect cubes of even integers, namely 12³ = 1728, 16³ = 4096, and 18³ = 5832, whereas 14³ is equal to 2744.

Explanation

The number 826 is the odd one out because it is not divisible by 5, whereas all the other numbers in the group are perfectly divisible by 5 as they end with either 0 or 5.

Explanation

The series follows a pattern where the alphabetical position of each letter in a term is increased by 4 to obtain the corresponding letter of the subsequent term.

Applying this pattern to the first letters: C (position 3) + 4 = G (position 7) G (position 7) + 4 = K (position 11) K (position 11) + 4 = O (position 15)

Applying this pattern to the second letters: D (position 4) + 4 = H (position 8) H (position 8) + 4 = L (position 12) L (position 12) + 4 = P (position 16)

Explanation

Each term in the series consists of four consecutive letters in reverse alphabetical order.

The first letters of the consecutive terms follow a pattern of adding 4 to their positional values in the English alphabet: E (5) + 4 = I (9) I (9) + 4 = M (13) M (13) + 4 = Q (17)

Starting the next term with the letter Q and writing the letters in reverse alphabetical order yields Q, P, O, N.

Explanation

The terms of the series increase by the cubes of consecutive natural numbers starting from 2.

The difference between the first and second terms is: 21 - 13 = 8 = 2³

The difference between the second and third terms is: 48 - 21 = 27 = 3³

The difference between the third and fourth terms is: 112 - 48 = 64 = 4³

Following this sequence, the next difference must be 5³: 125 = 5³

Adding this difference to the fourth term gives the missing term: 112 + 125 = 237

Explanation

Statement I asserts that pre-school culture is prevailing in all parts of the country now. The widespread prevalence of this culture directly implies a corresponding growth and rise in the establishment of these institutions, meaning that the number of preschools is increasing in all parts of the country. This makes Conclusion I a direct and logical deduction from the given premises. Conversely, there is no information in either statement regarding any changes in the behavior patterns of children due to early exposure to the outer world, making Conclusion II an invalid deduction.

Explanation

The given series represents the sequential stages of human growth and development in chronological order. An individual starts as an infant, progresses through childhood, enters adolescence, and then transitions into adulthood. Therefore, the next stage in this chronological sequence of life stages is being an adult.

Explanation

There are five positions in the row, numbered 1 to 5 from left to right.

Since P is at an end and third to the right of O, P must be at the right end (position 5) because O cannot be to the left of P if P is at the left end. This places O at position 2 (since 5 - 3 = 2).

The remaining vacant positions are 1, 3, and 4, which must be occupied by M, N, and Q.

The condition states that N is to the right of Q but to the left of P. This means Q is to the left of N. Placing Q at position 3 and N at position 4 satisfies this condition, as N is to the right of Q and to the left of P (position 5).

With positions 2, 3, 4, and 5 occupied by O, Q, N, and P respectively, the only remaining position 1 at the left end must be occupied by M. This gives the final arrangement from left to right as M, O, Q, N, P.

Explanation

To arrange the words in the sequence in which they occur in a dictionary, they are compared letter by letter from left to right.

All five words begin with the letter M.

Comparing the second letters: Manage has a. Misleader has i. Mobil, Monarchy, and Movies have o.

Since a comes before i, and i comes before o, Manage (iv) is the first word, followed by Misleader (i).

Now, comparing the third letters of the remaining three words that begin with Mo: Mobil has b. Monarchy has n. Movies has v.

Since b comes before n, and n comes before v, the alphabetical order of these three words is Mobil (iii), Monarchy (ii), and Movies (v).

Combining these, the complete alphabetical sequence is Manage (iv), Misleader (i), Mobil (iii), Monarchy (ii), and Movies (v).

Explanation

The word FIRMLY is split into two equal halves of three letters each: FIR and MLY. The letters of each half are then reversed to get RIF and YLM. For the first reversed half, the letters are shifted forward by +2 in the alphabetical order: R + 2 = T I + 2 = K F + 2 = H This yields the first part of the code: TKH.

For the second reversed half, the letters are shifted backward by -2: Y - 2 = W L - 2 = J M - 2 = K This yields the second part of the code: WJK.

Combining both parts results in the coded word TKHWJK.

Applying this identical pattern to PUBLIC: The word is split into PUB and LIC. Reversing each half gives BUP and CIL. Shifting the first reversed half by +2: B + 2 = D U + 2 = W P + 2 = R This yields the first part: DWR.

Shifting the second reversed half by -2: C - 2 = A I - 2 = G L - 2 = J This yields the second part: AGJ.

Combining both parts yields the final coded word DWRAGJ.

Explanation

The pattern in each column follows the relation: Row 1 = Row 2 + (Row 3 × Row 4)

For the first column: 4 + (5 × 3) = 4 + 15 = 19

For the second column: 5 + (6 × 4) = 5 + 24 = 29

Applying the same pattern to the third column: 3 + (? × 6) = 45 ? × 6 = 45 - 3 ? × 6 = 42 ? = 7

Explanation

The mathematical operation represented by the symbol × is to find the average of the two numbers. This relation is expressed by the formula:

Result = (A + B) / 2

Applying this formula to the given examples:

(52 + 14) / 2 = 66 / 2 = 33

(44 + 8) / 2 = 52 / 2 = 26

(86 + 14) / 2 = 100 / 2 = 50

Using the same relation for the final expression:

(43 + 15) / 2 = 58 / 2 = 29

Explanation

When we place the letters of option c) sequentially into the gaps of the series, the filled series becomes:

ab b d a b b d a b b

By dividing this completed series into groups of four letters, a clear repeating pattern emerges:

abbd / abbd / abb(d)

The pattern is a simple repetition of the four-letter sequence abbd. Therefore, the letters b, a, d, b sequentially complete the series.

Explanation

Let the starting point be at the origin (0, 0).

First, Suraj walks 20 m South, reaching the coordinate: (0, -20)

Next, he turns left (facing East) and walks 18 m, reaching the coordinate: (18, -20)

He then turns left (facing North) and walks 18 m, reaching the coordinate: (18, -20 + 18) = (18, -2)

Finally, he turns right (facing East) and walks 10 m, reaching the coordinate: (18 + 10, -2) = (28, -2)

Since the final x-coordinate is positive (East) and the y-coordinate is negative (South), his direction from the starting point is South-East.

To find the straight-line distance from the starting point, we use the distance formula: Distance = √(28² + (-2)²) Distance = √(784 + 4) Distance = √788 m

Explanation

The word BOARD is represented by the code 32, 76, 04, 21, 55. This is verified by checking the row and column representation for each letter.

For the letter B, looking at Matrix-I, row 3 and column 2 contains the letter B, giving the code 32.

For the letter O, looking at Matrix-II, row 7 and column 6 contains the letter O, giving the code 76.

For the letter A, looking at Matrix-I, row 0 and column 4 contains the letter A, giving the code 04.

For the letter R, looking at Matrix-I, row 2 and column 1 contains the letter R, giving the code 21.

For the letter D, looking at Matrix-II, row 5 and column 5 contains the letter D, giving the code 55.

Explanation

We can simplify the statement step-by-step:

Rahul's paternal grandfather's only son refers to Rahul's father.

The daughter of Rahul's father is Rahul's sister.

The brother of Rahul's sister is Rahul's brother.

Thus, the boy in the picture is Rahul's brother.

Explanation

The relationship between the first pair of words is synonymous, as both dissemble and feign mean to disguise, pretend, or give a false appearance. Following the same logic, divulge means to make known or reveal private or sensitive information. Therefore, the corresponding word that shares the same synonymous relationship is disclose, which also means to make information known or to reveal.

Explanation

The positions of the letters E and F in the alphabetical series are 5 and 6, respectively. Adding 10 to these positions yields 15 and 16, which correspond to the letters O and P. Following the same logic for the second pair, the positions of S and T are 19 and 20, respectively. Subtracting 10 from these positions gives 9 and 10, which correspond to the letters I and J.

Explanation

The relationship between the first two terms is based on opposite letters in the alphabetical position (T is opposite to G, and Z is opposite to A, as their position sums equal 27). Applying the same logic to QR, the opposite of Q is J and the opposite of R is I, which gives JI. Option D (IJ) represents these correct opposite letters, likely with a reversed order typo.

Explanation

The relationship between the numbers in the first pair is determined by multiplying the first number by 4 and then adding 2 to the result.

(15 × 4) + 2 = 60 + 2 = 62

Applying the same mathematical logic to the second pair:

(16 × 4) + 2 = 64 + 2 = 66

Explanation

Bhilai is situated in Chhattisgarh and is widely known for the Bhilai Steel Plant, which is a major steel-producing facility. In contrast, the other locations are sites of operational nuclear power stations in India.

Explanation

The letter group BOI contains the consonant letter B, whereas the other letter groups are composed entirely of vowels.

Explanation

The sum of the digits of 5611 is 5 + 6 + 1 + 1 = 13. In contrast, the sum of the digits of each of the other numbers is equal to 20.

Explanation

The number 1331 is a perfect cube, equal to 11³, whereas the other numbers in the group are perfect squares.

Explanation

The series is formed by listing the Vice Presidents of India in reverse chronological order. Mohammad Hamid Ansari served as the 12th Vice President from 2007 to 2017. Bhairon Singh Shekhawat served as the 11th Vice President from 2002 to 2007. Krishan Kant served as the 10th Vice President from 1997 to 2002. Following this sequence, the next term must be the 9th Vice President of India, which is K.R. Narayanan, who served from 1992 to 1997.

Explanation

The series is formed by incrementing the alphabetical positions of the letters by a decreasing difference of +5, +4, +3, and +2.

For the first letter of each term, the position changes as follows: G (7) + 5 = L (12) L (12) + 4 = P (16) P (16) + 3 = S (19) S (19) + 2 = U (21)

For the second letter of each term, the position changes as follows: H (8) + 5 = M (13) M (13) + 4 = Q (17) Q (17) + 3 = T (20) T (20) + 2 = V (22)

Combining these letters yields the term UV.

Explanation

Each term in the series consists of two consecutive letters in reverse alphabetical order. The first letters of successive terms decrease by 4 positions in the alphabet: S (19), O (15), K (11), and G (7). Similarly, the second letters of successive terms also decrease by 4 positions: R (18), N (14), J (10), and F (6). Combining these two sequences gives the missing term KJ.

Explanation

The given series follows a pattern where each term is generated by multiplying the preceding term by 2 and then adding 1.

Term 1 = 60 Term 2 = 60 × 2 + 1 = 121 Term 3 = 121 × 2 + 1 = 243 Term 4 = 243 × 2 + 1 = 487

Explanation

Statement I clearly states that holidays are meant to relax, rejuvenate, and recollect energy. The concept of relaxing and recollecting energy directly corresponds to resting. Thus, the primary purpose of holidays is indeed for resting, making Conclusion I a direct and logically sound derivation from the first statement.

Explanation

We can represent the heights of the boys using inequality signs in descending order.

From the first statement, Q is taller than T but shorter than P: P > Q > T

From the second statement, S is shorter than T but taller than R: T > S > R

Combining these two relations gives a single continuous inequality: P > Q > T > S > R

This sequence shows that R has the minimum height among all five boys.
