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

Explanation

In WSM, the alphabetical positions of the letters are W = 23, S = 19, and M = 13. The difference between W and S is 4 (23 - 19 = 4), whereas the difference between S and M is 6 (19 - 13 = 6). This group of letters does not follow the uniform pattern of subtracting 4 between consecutive letters, which is consistently maintained in the other letter groups where each successive letter is obtained by subtracting 4 from the preceding letter's position.

Explanation

The general relation followed in the given pairs is that the second number is obtained by multiplying the first number by 4. For the first pair, multiplying 278 by 4 yields 1112, which does not equal the given second number of 1122. Therefore, this pair deviates from the common logic of the other pairs and is the odd one out.

Explanation

The coding pattern alternates between the reverse positional value and the normal positional value of the letters in the English alphabet.

For odd-positioned letters (1st, 3rd, 5th, 7th), the code is the reverse alphabet position, calculated as 27 minus the normal position. For even-positioned letters (2nd, 4th, 6th, 8th), the code is the normal alphabet position.

Applying this pattern to INVASIVE: I (1st letter, odd position): Reverse of 9 is 27 - 9 = 18 N (2nd letter, even position): Normal position = 14 V (3rd letter, odd position): Reverse of 22 is 27 - 22 = 5 A (4th letter, even position): Normal position = 1 S (5th letter, odd position): Reverse of 19 is 27 - 19 = 8 I (6th letter, even position): Normal position = 9 V (7th letter, odd position): Reverse of 22 is 27 - 22 = 5 E (8th letter, even position): Normal position = 5

Combining these values yields 1814518955.

Explanation

From the given information, M is the brother of N, and N is the sister of O, which means M, N, and O are all siblings. Since L is the father of M, L is also the father of N and O. It is given that O is the daughter of P. Since L is already the father of the siblings, P must be the mother of O, and consequently, the mother of N.

Explanation

The coding pattern involves reversing the given word and then shifting each letter backward by two positions in the English alphabetical order.

First, reverse the letters of the word SCREEN to get NEERCS. Now, subtract 2 from the alphabetical position of each letter: N (14) - 2 = L (12) E (5) - 2 = C (3) E (5) - 2 = C (3) R (18) - 2 = P (16) C (3) - 2 = A (1) S (19) - 2 = Q (17) This yields the code LCCPAQ.

Applying the same logic to SKILLS, first reverse the word to get SLLIKS. Subtracting 2 from the alphabetical position of each letter: S (19) - 2 = Q (17) L (12) - 2 = J (10) L (12) - 2 = J (10) I (9) - 2 = G (7) K (11) - 2 = I (9) S (19) - 2 = Q (17) This yields the code QJJGIQ.

Explanation

The pattern in the letter groups is a constant subtraction of 4 from the alphabetical position of each letter.

For AMG to WIC: A (1) - 4 = W (23) (counting backward in a circular alphabet) M (13) - 4 = I (9) G (7) - 4 = C (3)

Applying the same logic to NZT: N (14) - 4 = J (10) Z (26) - 4 = V (22) T (20) - 4 = P (16)

This yields the letters JVP.

Explanation

When arranging the words in dictionary order, they appear in the sequence: Dieldrin, Dietetic, Distock, Distrum, and Distrus. Therefore, the word that comes at the second position is Dietetic, which corresponds to Option B.

Explanation

The relation between the numbers in each pair follows the pattern where the second number is obtained by multiplying the first number by one-third of itself.

Formula: Second number = First number × (First number ÷ 3)

For the first pair: 6 × (6 ÷ 3) = 6 × 2 = 12

For the second pair: 15 × (15 ÷ 3) = 15 × 5 = 75

Applying this pattern to the third pair: 18 × (18 ÷ 3) = 18 × 6 = 108

Explanation

The relationship between the numbers in each pair follows the pattern where the second number is obtained by multiplying the first number by 6 and then adding 1.

Using the formula: Second number = (First number × 6) + 1

Applying this to the first pair: (14 × 6) + 1 = 84 + 1 = 85

Applying this to the second pair: (20 × 6) + 1 = 120 + 1 = 121

Applying the same pattern to the fifth number: (11 × 6) + 1 = 66 + 1 = 67

Explanation

The relationship between the first two groups of letters is based on shifting each letter forward by one position in the English alphabetical order.

L + 1 = M R + 1 = S E + 1 = F A + 1 = B

Applying the same pattern to the third group of letters:

B + 1 = C S + 1 = T F + 1 = G X + 1 = Y

Explanation

The relationship between the numbers in each set follows the formula:

(First number × Second number) ÷ 4 = Third number

Applying this to the given sets: First set: (48 × 16) ÷ 4 = 48 × 4 = 192 Second set: (22 × 62) ÷ 4 = 11 × 31 = 341

Applying the same formula to the correct option: (84 × 78) ÷ 4 = 21 × 78 = 1638

Explanation

The coding scheme is based on finding the sum of the alphabetical positions of each letter in the word, and then calculating the single-digit sum (digital sum) of that total.

For ROUTE: R = 18, O = 15, U = 21, T = 20, E = 5 Sum = 18 + 15 + 21 + 20 + 5 = 79 Single-digit sum = 7 + 9 = 16 → 1 + 6 = 7

For SHARE: S = 19, H = 8, A = 1, R = 18, E = 5 Sum = 19 + 8 + 1 + 18 + 5 = 51 Single-digit sum = 5 + 1 = 6

Following the same logic for TABLE: T = 20, A = 1, B = 2, L = 12, E = 5 Sum = 20 + 1 + 2 + 12 + 5 = 40 Single-digit sum = 4 + 0 = 4

Explanation

When the letters from pslilsprs are sequentially placed in the blanks of the series, the completed string becomes:

p l f r s p l f i r s p l f i r s p l f i r s

This completed series reveals a repeating pattern of groups:

The first group of five letters is p l f r s.

The subsequent groups of six letters are p l f i r s, which repeat three times as p l f i r s, p l f i r s, and p l f i r s.

Explanation

In options B, C, and D, the relationship is Product - Raw Material, as a sack is made of jute, a road is made of asphalt, and a wall is made of bricks. In option A, the relationship is reversed to Raw Material - Product, as sugarcane is the raw material used to make jaggery, making it the odd pair.

Explanation

In the given sets, the relationship between the three numbers (A, B, C) is based on constant differences between consecutive terms: B - A = 67 C - B = 68

Applying this logic to the first given set (812, 879, 947): 879 - 812 = 67 947 - 879 = 68

Applying this logic to the second given set (648, 715, 783): 715 - 648 = 67 783 - 715 = 68

The set (612, 679, 747) follows the exact same pattern: 679 - 612 = 67 747 - 679 = 68

Explanation

The given word pair Dry : Wet consists of antonyms, as dry is the direct opposite of wet. Similarly, the pair Healthy : Sick consists of antonyms, where healthy is the direct opposite of sick.

Explanation

E is the brother of F, which makes E and F siblings with E being male. F is the sister of G, which means F and G are also siblings. Since E, F, and G belong to the same generation of siblings, and E is male, E is the brother of G.

Explanation

The operation ⊕ is defined by the formula: a ⊕ b = 3 × (a + b)

Applying this formula to the given relations: 13 ⊕ 62 = 3 × (13 + 62) = 3 × 75 = 225 4 ⊕ 38 = 3 × (4 + 38) = 3 × 42 = 126

Applying the same formula to the required expression: 29 ⊕ 17 = 3 × (29 + 17) = 3 × 46 = 138

Explanation

The given words are arranged in a descending order of geographical hierarchy, starting from the largest entity and moving to the smallest.

The World is the largest entity, which contains the continent of Asia. Asia contains the country of India. Within India is the state of Uttar Pradesh, and the Taj Mahal is a monument located within Uttar Pradesh. This descending geographical order is represented as World (5) → Asia (2) → India (1) → Uttar Pradesh (3) → Taj Mahal (4), resulting in the sequence 5, 2, 1, 3, 4.

Explanation

The position values of the letters in the English alphabet are V = 22, Z = 26, and C = 3 (or 29).

The difference between the first and second letter is: 26 - 22 = 4

The difference between the second and third letter is: 29 - 26 = 3

This letter group has a pattern of +4 and +3, which deviates from the standard pattern of +4 and +4 followed by the other groups where each consecutive letter is obtained by adding 4.

Explanation

From the statement All G are N, we know that the entire set G is contained within the set N. Since all members of G are also members of N, it naturally follows by immediate inference that there are some members of N that are G. Therefore, the conclusion Some N are G logically and definitely follows.

The statement No A is N indicates that there is no overlap between set A and set N. Since set G is entirely inside set N, there can be no overlap between set G and set A. Hence, no G is A and no A is G, making conclusions I and III invalid. Thus, only conclusion II follows.

Explanation

The relationship between the words is based on a professional and their primary workplace. A teacher is a professional who works in a school to educate students. Following the same logic, a scientist is a professional who works in a laboratory to conduct scientific research and experiments.

Explanation

The given series is an arithmetic progression where each term is obtained by adding a constant difference to the preceding term.

The common difference d is calculated as: d = 148 - 89 = 59 d = 207 - 148 = 59 d = 266 - 207 = 59

Using the relation for the next term: Next term = Previous term + d Next term = 266 + 59 = 325

Explanation

Using the BODMAS rule, the expressions with the division operator ÷ are:

I. 24 ÷ 8 × 2 + 7 - 6 II. 8 × 6 - 9 ÷ 3 + 10

Interchanging the signs × and -:

For Expression I: 24 ÷ 8 - 2 + 7 × 6

Applying BODMAS: Division: 24 ÷ 8 = 3 Multiplication: 7 × 6 = 42 Result: 3 - 2 + 42 = 43

For Expression II: 8 - 6 × 9 ÷ 3 + 10

Applying BODMAS: Division: 9 ÷ 3 = 3 Multiplication: 6 × 3 = 18 Result: 8 - 18 + 10 = 0

Explanation

In the given number pairs, the relation between the left number x and the right number is x³ + 2. For the first pair, 14³ + 2 = 2744 + 2 = 2746, which is not equal to 2762. Therefore, this pair does not follow the logic and is the odd one out.

Explanation

The coding pattern of the letters in the word is as follows:

1st letter of code = (5th letter of word) - 4 2nd letter of code = (2nd letter of word) - 2 3rd letter of code = (3rd letter of word) - 4, written in lowercase 4th letter of code = (4th letter of word) - 6 5th letter of code = (1st letter of word) - 4

Applying this to GRMTS: G = 7, R = 18, M = 13, T = 20, S = 19

1st letter: S (19) - 4 = 15 = O 2nd letter: R (18) - 2 = 16 = P 3rd letter: M (13) - 4 = 9 = I 4th letter: T (20) - 6 = 14 = N 5th letter: G (7) - 4 = 3 = C This gives OPINC.

Applying the same pattern to BATCH: B = 2, A = 1, T = 20, C = 3, H = 8

1st letter: H (8) - 4 = 4 = D 2nd letter: A (1) - 2 = -1 (or 25) = Y 3rd letter: T (20) - 4 = 16 = p (lowercase) 4th letter: C (3) - 6 = -3 (or 23) = W 5th letter: B (2) - 4 = -2 (or 24) = X

Combining these, we get DYpWX.

Explanation

The coding pattern involves reversing the order of the letters in the word and then shifting each letter backward by 3 positions in the alphabetical order (with A wrapping around to Z).

Applying this pattern to CHAIRS:

Reverse the word: CHAIRS becomes S R I A H C

Shift each letter backward by 3 positions: S (19) - 3 = P (16) R (18) - 3 = O (15) I (9) - 3 = F (6) A (1) - 3 = X (24) H (8) - 3 = E (5) C (3) - 3 = Z (26)

Putting these letters together yields POFXEZ.

Explanation

In the letter group IGE, the alphabetical positions of the letters are I = 9, G = 7, and E = 5. The difference between consecutive letters is -2 and -2 (9 to 7 is -2, and 7 to 5 is -2). This differs from the other letter groups, which all follow a pattern of -2 followed by -3.

Explanation

L is the father of N. Since J is the brother of L, J is N's paternal uncle, which is N's father's brother. H is married to J, making her the wife of N's father's brother, which is the father's brother's wife.

Explanation

The terms represent the chronological stages of education from the lowest to the highest level of study.

Nursery is the early childhood education stage. Matriculation is the completion of 10th-grade schooling. Higher Secondary is the completion of 12th-grade schooling. Graduation is the university level for a bachelor's degree. Post-Graduation is the advanced university level for a master's degree.

Arranging these educational qualifications in ascending order of their levels gives the sequence of Nursery (3), Matriculation (4), Higher Secondary (5), Graduation (2), and Post-Graduation (1). This corresponds to the sequence 3, 4, 5, 2, 1.

Explanation

The series follows a specific pattern for each letter position of the terms.

For the first letter, the positional values in alphabetical order decrease by 4 in each step: A (1 or 27) minus 4 is W (23) W (23) minus 4 is S (19) S (19) minus 4 is O (15) O (15) minus 4 is K (11)

For the second letter, the positional values increase by 6 in each step: B (2) plus 6 is H (8) H (8) plus 6 is N (14) N (14) plus 6 is T (20) T (20) plus 6 is Z (26)

For the third letter, the pattern alternates between C and P: The terms have C, then P, then C, then P, making the next letter C.

Combining these letters gives the term KZC.

Explanation

The relation between the pairs of numbers is based on adding a constant difference of 133 to the first number to obtain the second number.

For the first pair: 434 + 133 = 567

For the second pair: 617 + 133 = 750

Following the same logic for the third pair: 839 + 133 = 972

Explanation

By correcting the operator, the original equation is: 21 ÷ 14 × 3 + 48 - 37

After interchanging the numbers 14 and 21, the equation becomes: 14 ÷ 21 × 3 + 48 - 37

Using the BODMAS rule, perform the operations in order:

First, solve the division: 14 ÷ 21 = 2/3

Next, solve the multiplication: 2/3 × 3 = 2

Next, perform the addition: 2 + 48 = 50

Finally, perform the subtraction: 50 - 37 = 13

Explanation

The relationship between the first pair is part-to-whole, where a cockpit is a constituent part of an aeroplane. This relationship is presented in the specific order of part : whole. Following the same logic, a student is an individual member that constitutes a class, which represents a part-to-whole relationship in the exact same order.

Explanation

The operation @ is defined by subtracting the second number from the first number and then reversing the digits of the resulting difference.

First, test this pattern with the given equations: 617 − 342 = 275. Reversing the digits of 275 gives 572. 483 − 342 = 141. Reversing the digits of 141 gives 141.

Now, apply this same pattern to find the value of 280@82: 280 − 82 = 198. Reversing the digits of 198 gives 891.

Explanation

A thermometer is a scientific instrument used to measure temperature. Similarly, a seismograph is a scientific instrument used to detect, measure, and record the intensity and duration of earthquakes by tracking seismic waves.

Explanation

Dhaka is the capital city of Bangladesh, which is a geographical and political entity, whereas the other options represent official currencies.

Explanation

The given series is: 51, 55, 64, 80, 105, ?

To find the pattern, calculate the differences between consecutive terms: 55 - 51 = 4 = 2² 64 - 55 = 9 = 3² 80 - 64 = 16 = 4² 105 - 80 = 25 = 5²

The differences are successive perfect squares: 2², 3², 4², and 5². Following this logic, the next difference must be 6², which is 36.

Adding 36 to the last term: 105 + 36 = 141

Explanation

The coding pattern uses the sum of the reverse positional values (opposite alphabetical positions where A = 26, B = 25, ..., Z = 1) of the letters, multiplied by the total number of letters in the word.

For JAIL: Reverse values: J = 17, A = 26, I = 18, L = 15 Sum = 17 + 26 + 18 + 15 = 76 Code = 76 × 4 = 304

For LAWN: Reverse values: L = 15, A = 26, W = 4, N = 13 Sum = 15 + 26 + 4 + 13 = 58 Code = 58 × 4 = 232

Applying this logic to NAVY: Reverse values: N = 13, A = 26, V = 5, Y = 2 Sum = 13 + 26 + 5 + 2 = 46 Code = 46 × 4 = 184

Explanation

The first statement, Some R are C, establishes that there is an overlap between set R and set C, which means that at least some C are R. This does not mean that all C are R, making Conclusion II invalid.

The second statement, All R are K, means that the entire set R is a subset of set K. This does not imply that all of K is inside R, which makes Conclusion I invalid.

Combining the two statements, since the overlapping part of R and C lies entirely within K (as all R are K), we can only conclude that some C are K. This does not support the claim that all C are K, making Conclusion III invalid.

Explanation

The relationship between the three numbers (a, b, c) in the given sets is defined by the formula c = a × b × 6.

Applying this formula to the first set (13, 7, 546): 13 × 7 × 6 = 91 × 6 = 546

Applying this formula to the second set (14, 15, 1260): 14 × 15 × 6 = 210 × 6 = 1260

Applying the same formula to the set in the correct option (28, 21, 3528): 28 × 21 × 6 = 588 × 6 = 3528

Explanation

The relationship between the letter groups is based on reversing the order of the letters.

The first group QTY is written in reverse order to get YTQ.

Applying the same pattern to the second group, the letters of ENR are reversed to obtain RNE.

Explanation

The numbers in each set follow the relation: 2 × (first number) + (second number) = (third number).

Applying this logic to the given sets: For (10, 22, 42): 2 × 10 + 22 = 20 + 22 = 42 For (15, 14, 44): 2 × 15 + 14 = 30 + 14 = 44

Similarly, for the set in option C, (13, 12, 38): 2 × 13 + 12 = 26 + 12 = 38

Explanation

The relation followed in the other pairs is that the number on the right is the cube of the number on the left, which can be represented as x → x³.

Calculating the cube of 14: 14³ = 14 × 14 × 14 = 2744

Since the given value is 2844 instead of 2744, this pair does not follow the established rule and is the odd one out.
