SSC CHSL Tier 1 2022 General Intelligence & Reasoning Questions with Solutions

Explanation

The relationship between the first pair of letters is based on adding 5 to the alphabetical positions of both letters.

The alphabetical positions of the letters in NA are: N = 14 A = 1

Adding 5 to these positions: 14 + 5 = 19, which corresponds to S 1 + 5 = 6, which corresponds to F This gives SF.

Applying the same logic to OB: O = 15 B = 2

Adding 5 to these positions: 15 + 5 = 20, which corresponds to T 2 + 5 = 7, which corresponds to G

This results in the letters TG.

Explanation

A mirror primarily functions by reflecting light that falls on its surface, which is the phenomenon of reflection of light. Similarly, a prism is designed to split white light into its constituent spectrum of colors as the light passes through it. This splitting of white light into its component wavelengths due to refraction at different angles is known as the dispersion of light.

Explanation

The series follows an alternating mathematical pattern of division by 2 and multiplication by 3:

36 ÷ 2 = 18 18 × 3 = 54 54 ÷ 2 = 27 27 × 3 = 81

Following this sequence, the next operation is division by 2:

81 ÷ 2 = 40.5

To verify, the subsequent step is multiplication by 3:

40.5 × 3 = 121.5

Explanation

In the given number pairs, the relation between the first number x and the second number y follows the rule y = x + 999.

For the pair 17 - 1006, applying this rule gives 17 + 999 = 1016, whereas the given number is 1006. Since the difference here is 1006 - 17 = 989, it does not satisfy the relation followed by the other pairs, making it the odd one out.

Explanation

Suman's brother's father is Suman's father. The daughter of Suman's father is Suman's sister, given the assumption that the photo is not of Suman herself. Therefore, the girl in the photo is Suman's sister.

Explanation

The analogy represents the relationship between an animal or bird and its number of legs. A cow has four legs. Following the same logic, a crow has two legs.

Explanation

A hygrometer is a scientific instrument used to measure the moisture content or humidity in the air. Similarly, a seismograph is an instrument designed to detect and record the strength, duration, and direction of ground vibrations produced by an earthquake. Both pairs represent the relationship between a measuring device and the physical phenomenon it measures.

Explanation

The given series consists of the squares of consecutive natural numbers starting from 13:

13² = 169 14² = 196 15² = 225 16² = 256

Following this pattern, the next term in the series is the square of 17:

17² = 289

Explanation

The numbers in each set follow the pattern where the third number is obtained by multiplying the first and second numbers and then adding 2 to the product.

First number × Second number + 2 = Third number

In the first set (8, 6, 50): 8 × 6 + 2 = 48 + 2 = 50

In the second set (24, 4, 98): 24 × 4 + 2 = 96 + 2 = 98

Applying the same pattern to the option (18, 6, 110): 18 × 6 + 2 = 108 + 2 = 110

Explanation

The statement "Some C are D" establishes that there is a partial overlap between set C and set D. The statement "All D are E" establishes that set D is completely contained within set E. Combining these statements, we can only conclude that some C are E and some E are D. Conclusion I, "All C are E", is incorrect because only a portion of C is guaranteed to be in E. Conclusion II, "All D are C", is incorrect because the partial overlap only guarantees that some D are C, not all. Conclusion III, "All E are D", is incorrect because while all D are in E, set E may contain elements that are not in D. Therefore, none of the given conclusions logically follow.

Explanation

The operator % represents the addition (+) operation in the given pattern.

We can verify this logic with the given examples: First case: 52 + 38 + 84 = 174 Second case: 16 + 12 + 95 = 123

Applying the same addition pattern to the final expression: 44 + 28 + 7 = 79

Explanation

Interchanging the signs + and × in Equation I: 5 + 12 - 15 × 20 ÷ 30

Applying BODMAS rules: 5 + 12 - 15 × 2/3 5 + 12 - 10 17 - 10 = 7

Since the LHS equals the RHS, Equation I is correct.

Interchanging the signs + and × in Equation II: 51 ÷ 17 + 9 × 10 - 8

Applying BODMAS rules: 3 + 9 × 10 - 8 3 + 90 - 8 93 - 8 = 85

Since the LHS equals the RHS, Equation II is also correct.

Explanation

In the standard pattern of the letter groups, the second letter is obtained by subtracting 3 from the first letter, the third letter is obtained by subtracting 4 from the second letter, and the fourth letter is the alphabetical opposite of the third letter.

In GDAZ, the positions of the letters are G (7), D (4), A (1), and Z (26). The transition from G to D is 7 - 3 = 4, but the transition from D to A is 4 - 3 = 1. Because this second transition is a subtraction of 3 instead of 4, GDAZ deviates from the required pattern.

Explanation

The coding scheme shifts each letter of the word forward in the alphabetical order by consecutive even numbers starting from 2.

For the word HUMAN: H (8) + 2 = J (10) U (21) + 4 = Y (25) M (13) + 6 = S (19) A (1) + 8 = I (9) N (14) + 10 = X (24)

Applying the same pattern to the word IMAGE: I (9) + 2 = K (11) M (13) + 4 = Q (17) A (1) + 6 = G (7) G (7) + 8 = O (15) E (5) + 10 = O (15)

Explanation

The relationship between the numbers in each pair follows the pattern: Second number = (First number - 3)³

Applying this pattern to the given pairs: For the third and fourth numbers: (15 - 3)³ = 12³ = 1728

For the fifth and sixth numbers: (11 - 3)³ = 8³ = 512

Applying the same logic to find the missing second number: (12 - 3)³ = 9³ = 729

Explanation

Comparing MOCK (9326) and MINK (2538), the common letters are M and K, and the common digits are 2 and 3. Thus, the set {M, K} corresponds to {2, 3}.

Comparing LUNE (5041) and LOUT (6714), the common letters are L and U, and the common digits are 1 and 4. Thus, the set {L, U} corresponds to {1, 4}.

In LOUT (6714), the remaining letters {O, T} must correspond to the remaining digits {6, 7}. In MOCK (9326), since {M, K} corresponds to {2, 3}, the remaining letters {O, C} correspond to {6, 9}. Comparing these, O must be 6.

In LUNE (5041), the remaining letters {N, E} must correspond to the remaining digits {0, 5}. In MINK (2538), since {M, K} corresponds to {2, 3}, the remaining letters {I, N} correspond to {5, 8}. Comparing these, N must be 5.

Since O = 6, N = 5, and M is either 2 or 3, the code for ONM must consist of the digits 6, 5, and either 2 or 3. This matches the combination of digits in 653.

Explanation

Crocodile belongs to the class Reptilia, representing a cold-blooded, egg-laying, predatory reptile. In contrast, sheep, cow, and goat are all warm-blooded, milk-producing mammalian herbivores belonging to the class Mammalia. This biological classification distinguishes the crocodile from the rest of the group.

Explanation

Each letter in the terms of the series follows a specific arithmetic progression based on its alphabetical position.

For the first letter, the pattern is adding 4 to the position value: R (18) + 4 = V (22) V (22) + 4 = Z (26) Z (26) + 4 = D (30, which is 4) D (4) + 4 = H (8)

For the second letter, the pattern is subtracting 6 from the position value: C (3) - 6 = W (23) W (23) - 6 = Q (17) Q (17) - 6 = K (11) K (11) - 6 = E (5)

For the third letter, the pattern is adding 8 to the position value: M (13) + 8 = U (21) U (21) + 8 = C (29, which is 3) C (3) + 8 = K (11) K (11) + 8 = S (19)

For the fourth letter, the pattern is subtracting 10 from the position value: G (7) - 10 = W (23) W (23) - 10 = M (13) M (13) - 10 = C (3) C (3) - 10 = S (19)

Combining these letters yields HESS.

Explanation

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

Comparing the first three letters of all words, Admirable has m as its third letter, so it comes first. Adorable has o as its third letter, which comes next, making it second. The remaining words Advantage, Advice, and Advise all share the first three letters Adv.

Comparing the fourth letter of these remaining words, Advantage has a, which comes before i, placing it third.

Between Advice and Advise, both share the first four letters Advi. Comparing their fifth letters, Advice has c which comes before s in Advise, making Advice fourth and Advise fifth.

This gives the alphabetical sequence 4, 5, 1, 2, 3.

Explanation

The relation in the pairs follows the logic where the second number is the square of the first number. In this pair, the square of 36 is 1296 (36² = 1296), which is not equal to the given number 1266.

Explanation

The relationship between the first pair of letters is determined by adding progressive values to their alphabetical positions.

For the first letter of each pair, the position is increased by 1: G (7) + 1 = H (8)

For the second letter of each pair, the position is increased by 2: T (20) + 2 = V (22)

Applying the same pattern to HU: H (8) + 1 = I (9) U (21) + 2 = W (23)

This yields the letters IW.

Explanation

Each letter position in the terms follows a specific arithmetic progression based on its alphabetical position.

First letter position: A (1), E (5), I (9), Q (17). The difference between consecutive letters is +4. The missing letter is 9 + 4 = 13, which is M.

Second letter position: B (2), J (10), R (18), H (8). The difference between consecutive letters is +8 in a cyclic alphabetical order of 26 letters. The missing letter is 18 + 8 = 26, which is Z.

Third letter position: C (3), N (14), Y (25), U (21). The difference between consecutive letters is +11 in a cyclic alphabetical order of 26 letters. The missing letter is 25 + 11 = 36, and 36 - 26 = 10, which is J.

Combining these letters yields MZJ.

Explanation

The relationship in the given pair is Place : Organism. An aquarium is an enclosure or container where fish live and are kept. Similarly, a hive is the structure where honeybees live. Both pairs follow the exact logical relationship of a habitat or living space followed by the living organism that resides in it.

Explanation

The coding pattern divides each eight-letter word into two halves of four letters each. For the first four letters, the code uses their opposite alphabetical positions, which is calculated as 27 minus the letter's positional value. For the last four letters, the code uses their actual alphabetical positions from 1 to 26.

Applying this pattern to the word SCENARIO:

For the first four letters, we find the opposite positional values: S is the 19th letter, so opposite is 27 - 19 = 8. C is the 3rd letter, so opposite is 27 - 3 = 24. E is the 5th letter, so opposite is 27 - 5 = 22. N is the 14th letter, so opposite is 27 - 14 = 13.

For the last four letters, we find the actual positional values: A is the 1st letter, which gives 1. R is the 18th letter, which gives 18. I is the 9th letter, which gives 9. O is the 15th letter, which gives 15.

Combining these values together in order gives 8242213118915.

Explanation

The alphabetical positions of the letters in OSX are O = 15, S = 19, and X = 24. The difference between O and S is 4, while the difference between S and X is 5. This breaks the consistent pattern of adding 4 between consecutive letters found in the other groups, making OSX the odd one out.

Explanation

The relationship between the numbers in each pair follows the pattern where the second number is the square of the first number minus 2.

Mathematically, the pattern is (n - 2)² = m, where n is the first number and m is the second number.

For the first pair: (11 - 2)² = 9² = 81

For the second pair: (22 - 2)² = 20² = 400

For the third pair, let the missing number be x: (x - 2)² = 225 x - 2 = √225 x - 2 = 15 x = 15 + 2 x = 17

Explanation

The letter cluster RTU consists of letters with alphabetical positions 18, 20, and 21. The difference between the successive letters is +2 from R to T, and +1 from T to U. This pattern of non-consecutive letters makes it different from the other clusters, which all consist of three consecutive alphabetical letters with a constant difference of +1.

Explanation

In this group, Egypt is a country, whereas Tokyo and Oslo are the capital cities of Japan and Norway respectively. All other groups consist entirely of capital cities of various nations.

Explanation

In the given number pairs, the second number is obtained by reversing the order of the digits of the first number.

For 51624, reversing the digits gives 42615. For 51678, reversing the digits gives 87615. For 42675, reversing the digits gives 57624.

For 12311, reversing the digits should yield 11321, but the given number is 11231. This makes it the odd one out.

Explanation

The relation followed by the other pairs is that the second number is obtained by multiplying the first number by 2 and then adding 1, which can be represented by the formula y = 2x + 1, where x is the first number and y is the second number.

For the pair 1286-2578, applying this relation gives: 1286 × 2 + 1 = 2573

Since the given second number is 2578 instead of 2573, this pair does not satisfy the rule.

Explanation

Interchanging the numbers 4 and 6 in the equation 6 × 3 - 4 + 1 = 3 yields:

4 × 3 - 6 + 1 = 3

Evaluating the Left Hand Side (LHS) of the equation using the BODMAS rule:

LHS = 4 × 3 - 6 + 1 LHS = 12 - 6 + 1 LHS = 13 - 6 LHS = 7

Since the Left Hand Side is equal to 7 and the Right Hand Side (RHS) is equal to 3, the LHS is not equal to RHS. This makes the equation incorrect.

Explanation

The coding pattern in this language is to write the letters of the given word in reverse order.

The word LETTER written in reverse order becomes RETTEL.

Applying the same logic to the word RENAISSANCE, we write its letters from the last letter to the first letter, which gives ECNASSIANER.

Explanation

Since all silver are gold, the set of silver is entirely contained within the set of gold. This directly implies that there is an intersection between gold and silver, meaning some gold are silver. Therefore, Conclusion I logically follows.

Since no gold is platinum, and all silver are gold, no silver can be platinum. This makes Conclusion II logically incorrect. Thus, only Conclusion I follows.

Explanation

The given series follows a repeating pattern of the four-letter group abba.

To complete the pattern of abba abba abba, the series with its blanks must be ab_a_bba_b_a.

Placing the letters from the combination baab sequentially into the blanks completes the pattern: ab + b + a + a + bba + a + b + b + a = abbaabbaabba

This clearly forms three repetitions of the pattern abba.

Explanation

Sakshi is married to Subham, and Subham is the brother of Darshan. This means Subham and Darshan are siblings. Since Saloni is the mother of Darshan, she is also the mother of Subham. Because Subham is Sakshi's husband, his mother Saloni is the mother-in-law of Sakshi.

Explanation

The given mathematical operators are substituted as follows: The division operator (÷) means addition (+) The subtraction operator (-) means division (÷) The addition operator (+) means multiplication (×) The multiplication operator (×) means subtraction (-)

Substituting these operators into the given expression: 74 ÷ 11 - 33 + 42 × 16

We get the modified expression: 74 + 11 ÷ 33 × 42 - 16

Applying the BODMAS order of operations, division is performed first: 11 ÷ 33 = 1/3

Next, multiplication is performed: 1/3 × 42 = 14

The expression now becomes: 74 + 14 - 16

Performing addition and subtraction from left to right: 74 + 14 = 88 88 - 16 = 72

Explanation

The pattern of the given number pairs follows the relation where the first number in each pair is obtained by dividing the second number by 6.

For the first pair: 132 ÷ 6 = 22

For the third pair: 144 ÷ 6 = 24

Applying this same logic to the middle pair: 72 ÷ 6 = 12

Explanation

The given pair Treatment : Hospital follows the relationship of Service/Activity : Location, where treatment is the primary service provided at a hospital. Similarly, education is the primary service provided at a school, maintaining the exact same relationship and order.

Explanation

The relationship between the first pair of letter-clusters is established by adding 2 to the alphabetical position of each letter.

For IMQ to KOS: I + 2 = K M + 2 = O Q + 2 = S

Applying this same pattern to XBF: X + 2 = Z B + 2 = D F + 2 = H

Explanation

The given words can be arranged in a logical hierarchical order from the largest unit to the smallest unit in descending order.

A book (5) is composed of several chapters (4). Each chapter (4) consists of multiple paragraphs (3). Each paragraph (3) is made up of sentences (1). Finally, each sentence (1) is constructed using words, which are formed by individual letters (2).

This structural hierarchy from largest to smallest yields the sequence 5, 4, 3, 1, 2.

Explanation

To find the code for the digit 3, we compare the given statements to identify common digits and their corresponding code words.

Comparing the first statement '629' coded as 'namo te fek' and the second statement '943' coded as 'dump to te', the common digit is 9 and the common code word is 'te'. Therefore, 9 is coded as 'te'.

Comparing the second statement '943' coded as 'dump to te' and the third statement '748' coded as 'to fir tako', the common digit is 4 and the common code word is 'to'. Therefore, 4 is coded as 'to'.

In the second statement '943', the digits 9 and 4 are coded as 'te' and 'to' respectively. This leaves the remaining digit 3 to be coded as the remaining word 'dump'.

Explanation

The relationship between the numbers in the given sets follows the formula: First number = 2 × (Second number + Third number).

In the first set (66, 13, 20): 2 × (13 + 20) = 2 × 33 = 66

In the second set (298, 80, 69): 2 × (80 + 69) = 2 × 149 = 298

Applying this same relationship to the set (356, 111, 67): 2 × (111 + 67) = 2 × 178 = 356

Explanation

The relationship in the given pair is Capital : Country, as Ottawa is the capital city of Canada. Similarly, Nairobi is the capital city of Kenya, which maintains the exact same logical relationship and order of Capital : Country.

Explanation

The series is formed by adding successive powers of 3 to each term. Let us find the difference between consecutive numbers:

626 - 623 = 3 = 3¹ 635 - 626 = 9 = 3² 662 - 635 = 27 = 3³ 743 - 662 = 81 = 3⁴

Following this pattern, the next difference must be 3⁵ = 243.

The missing number in the series is: 743 + 243 = 986

Explanation

The operator A represents the addition operation. Adding the numbers in each equation gives 14 + 13 + 3 = 30 and 39 + 14 + 3 = 56. Applying this pattern, 28 + 11 + 4 = 43.

Explanation

According to Statement I, all N are Q. This can be represented as N being a subset of Q. Since all N are inside Q, it means that at least some part of Q is occupied by N. Therefore, the converse "Some Q are N" is definitely true, which makes Conclusion I logically follow.

According to Statement II, some H are Q, meaning there is an intersection between the set of H and the set of Q. Since some H are Q, it is also true that those intersecting elements of Q are H. Therefore, the converse "Some Q are H" is definitely true, which makes Conclusion II logically follow.

Since there is no specified relation or connection established between N and H, we cannot definitely conclude that some N are H. Thus, Conclusion III does not follow. Both conclusions I and II logically follow from the given statements.

Explanation

The given series consists of consecutive prime numbers starting from 2. The prime numbers in order are 2, 3, 5, 7, 11, and the next prime number in this sequence is 13.

Explanation

The relationship between the numbers in the set (24, 63, 70) is defined by the following operations:

Second number = (First number - 3) × 3 Third number = Second number + 7

Applying this to the numbers: (24 - 3) × 3 = 21 × 3 = 63 63 + 7 = 70

Explanation

To arrange the words in the sequence they occur in a dictionary, we compare them letter by letter from left to right.

All five words begin with the letters Ta. Comparing the third letters, we have c in Tackle, Tactless, and Tactful, k in Taken, and l in Talent. Since c comes before k and l in alphabetical order, the words starting with Tac must come first.

Comparing Tackle, Tactless, and Tactful, the fourth letter is k in Tackle and t in both Tactless and Tactful. Since k comes before t, Tackle is the first word in the sequence.

Next, comparing Tactless and Tactful, the fifth letter is l in Tactless and f in Tactful. Since f comes before l, Tactful comes before Tactless. This gives the starting sequence as Tackle (3), Tactful (4), and Tactless (2).

For the remaining two words, Taken and Talent, the third letters are k and l respectively. Since k comes before l, Taken (1) comes before Talent (5).

Combining these, the complete alphabetical sequence of the words is Tackle (3), Tactful (4), Tactless (2), Taken (1), and Talent (5), which corresponds to the sequence 3, 4, 2, 1, 5.

Explanation

H is the sister of I, and B is the mother of H, which means B is also the mother of I. Since I is the sister of J, all three (H, I, and J) are sisters. J is the daughter of R. Because B is the mother of these siblings, R must be the father of the siblings. Thus, R is the father of H.
