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

Explanation

The relationship between the numbers in each pair follows the formula y = x² - x, where x is the first number and y is the second number of the pair.

Applying this formula to the first pair: 15² - 15 = 225 - 15 = 210

Applying this formula to the third pair: 20² - 20 = 400 - 20 = 380

To find the missing first number x for the second pair where y = 90: x² - x = 90 x² - x - 90 = 0 (x - 10)(x + 9) = 0

Solving for the positive integer value of x yields x = 10.

Explanation

The relationship in the given pair Horse:Mare is based on gender, where the first word is the male animal (Horse) and the second word is its corresponding female counterpart (Mare). Following the same logic of male-to-female gender pair in the exact same order, Brother represents the male sibling and Sister represents the female sibling.

Explanation

The original equation is: 7 - 5 × 2 + 8 ÷ 4 = 17

By interchanging the signs + and - along with the numbers 7 and 5, the equation becomes: 5 + 7 × 2 - 8 ÷ 4 = 17

Applying the BODMAS rule: First, perform the division: 8 ÷ 4 = 2 Equation becomes: 5 + 7 × 2 - 2 = 17

Next, perform the multiplication: 7 × 2 = 14 Equation becomes: 5 + 14 - 2 = 17

Finally, perform the addition and subtraction from left to right: 19 - 2 = 17 17 = 17

Since the Left-Hand Side equals the Right-Hand Side, this interchange makes the equation correct.

Explanation

Pawan's mother's daughter is Pawan's sister. The sister of Pawan's sister is also Pawan's sister. Therefore, the lady in the photo is Pawan's sister.

Explanation

To find which equations are not correct, we interchange the signs + and - in both equations and evaluate them using the BODMAS rule.

For Equation I: 27 + 3 - 18 × 3 + 9 = 24 Interchanging + and - gives: 27 - 3 + 18 × 3 - 9 = 24 Applying BODMAS, we first perform multiplication: 18 × 3 = 54 Then, we solve the addition and subtraction from left to right: 27 - 3 + 54 - 9 = 24 + 54 - 9 = 78 - 9 = 69 Since 69 ≠ 24, Equation I is not correct.

For Equation II: 12 + 8 × 12 + 16 - 7 = 19 Interchanging + and - gives: 12 - 8 × 12 - 16 + 7 = 19 Applying BODMAS, we first perform multiplication: 8 × 12 = 96 Then, we solve the addition and subtraction: 12 - 96 - 16 + 7 = -84 - 16 + 7 = -100 + 7 = -93 Since -93 ≠ 19, Equation II is also not correct.

Both equations I and II are not correct after interchanging the signs.

Explanation

The coding scheme is based on the positions of the letters in the given word:

For letters at odd positions (1st, 3rd, 5th, 7th), the code is the reverse alphabetical position, calculated as 27 - standard position. For letters at even positions (2nd, 4th, 6th, 8th), the code is the standard alphabetical position.

Applying this rule to EDUCATOR:

1st letter: E (standard position 5) at an odd position -> 27 - 5 = 22 2nd letter: D (standard position 4) at an even position -> 4 3rd letter: U (standard position 21) at an odd position -> 27 - 21 = 6 4th letter: C (standard position 3) at an even position -> 3 5th letter: A (standard position 1) at an odd position -> 27 - 1 = 26 6th letter: T (standard position 20) at an even position -> 20 7th letter: O (standard position 15) at an odd position -> 27 - 15 = 12 8th letter: R (standard position 18) at an even position -> 18

Combining these codes sequentially gives: 2246326201218.

Explanation

The coding scheme shifts each letter of the word forward by 4 positions in the alphabetical order, and then reverses the sequence of the resulting letters.

Applying this to RAMEN: R (18) + 4 = V (22) A (1) + 4 = E (5) M (13) + 4 = Q (17) E (5) + 4 = I (9) N (14) + 4 = R (18) Reversing the shifted letters VEQIR yields RIQEV.

Applying the same logic to MODEL: M (13) + 4 = Q (17) O (15) + 4 = S (19) D (4) + 4 = H (8) E (5) + 4 = I (9) L (12) + 4 = P (16) Reversing the shifted letters QSHIP yields PIHSQ.

Explanation

The series follows a specific alphabetical pattern for each position of the letters in the terms:

First letter: Decreases by 1 position in alphabetical order: T (20) → S (19) → R (18) → Q (17) → P (16)

Second letter: Increases by 5 positions in alphabetical order: D (4) → I (9) → N (14) → S (19) → X (24)

Third letter: Decreases by 9 positions in alphabetical order, wrapping around the alphabet: S (19) → J (10) → A (1) → R (18) → I (9)

Combining these positions gives PXI.

Explanation

The relationship between the numbers in the set (A, B, C) is as follows:

The second number (B) is 11 times the sum of the digits of the first number (A): B = 11 × (sum of the digits of A)

The third number (C) is 22 times the absolute difference between the first number (A) and 45: C = 22 × |A - 45|

Let us verify this relationship with the given sets:

First Set (56, 121, 242): Sum of the digits of 56 = 5 + 6 = 11 B = 11 × 11 = 121 C = 22 × |56 - 45| = 22 × 11 = 242

Second Set (78, 165, 726): Sum of the digits of 78 = 7 + 8 = 15 B = 11 × 15 = 165 C = 22 × |78 - 45| = 22 × 33 = 726

Now, applying this same logic to Option B (36, 99, 198): Sum of the digits of 36 = 3 + 6 = 9 B = 11 × 9 = 99 C = 22 × |36 - 45| = 22 × 9 = 198

Explanation

M is the father of L. Since L is the brother of Q, M is also the father of Q. Q is the husband of S, which means S is Q's wife. Therefore, S is the daughter-in-law of Q's father, M.

Explanation

The relationship in the given pair is based on a tool and its primary function. A pen is an instrument used to write. Similarly, a spade is an instrument primarily used to dig soil, earth, or other ground materials.

Explanation

The relationship between the numbers in each pair is that the second number is formed by arranging the individual digits of the first number in ascending order.

In the first pair, the digits of 5432 rearranged in ascending order are 2, 3, 4, and 5, which forms the number 2345.

In the second pair, the digits of 6192 rearranged in ascending order are 1, 2, 6, and 9, which forms the number 1269.

Applying this same logic to the third pair, the digits of 7835 rearranged in ascending order are 3, 5, 7, and 8, which forms the number 3578.

Explanation

The relationship in the given pair is between a country and its official currency. The Yuan is the currency of China. Following the same logic, the Yen is the official currency of Japan.

Explanation

The logic followed by the numbers in the given sets is: Second number = First number ÷ 2 Third number = First number × 2

For the set (18, 9, 36): 18 ÷ 2 = 9 18 × 2 = 36

For the set (36, 18, 72): 36 ÷ 2 = 18 36 × 2 = 72

Similarly, for the set (32, 16, 64): 32 ÷ 2 = 16 32 × 2 = 64

Explanation

The series increases by consecutive even integers starting from 2.

The differences between consecutive terms are: 22 - 20 = 2 26 - 22 = 4 32 - 26 = 6 40 - 32 = 8

Following this pattern, the next difference in the sequence must be 10. Adding 10 to the last term gives: 40 + 10 = 50

Explanation

The alphabetical positions of the letters in PRV are P = 16, R = 18, and V = 22. The differences between consecutive letters in this group are +2 and +4. This (+2, +4) progression is the odd one out because all other groups follow a (+2, +3) progression.

Explanation

To arrange the words in dictionary order, we compare them letter by letter from left to right. All five words start with the prefix Conv. Looking at the fifth letter, the words Convect, Convent, Convert, and Convex have e, while Convict has i. Since e comes before i in the alphabet, Convict is placed last in the sequence.

Among the four words starting with Conve, we compare their sixth letters, which are c in Convect, n in Convent, r in Convert, and x in Convex. Arranging these letters in alphabetical order gives c, then n, then r, and finally x. This yields the sequential order of Convect as first, Convent as second, Convert as third, and Convex as fourth.

Explanation

The operator A represents the subtraction operation in the expression x A y A z = x - y - z.

Applying this formula to the given relations:

27 - 11 - 8 = 8

48 - 37 - 2 = 9

Using the same rule for the third expression:

56 - 5 - 3 = 48

Explanation

According to Statement I, all cherries are pink, which means the set of cherries is a subset of the set of pink. Since every cherry is pink, it logically follows that there is at least some overlap between the set of pink and the set of cherries. This direct conversion of the universal positive statement confirms that some pink are indeed cherry. Therefore, Conclusion III logically follows from the first statement.

Explanation

The relationship in the given pair is based on gender, where the first word is the male animal and the second word is its female counterpart. A dog is a male canine, and a bitch is a female canine. Applying the same logic, a bull is a male bovine, and a cow is the female bovine.

Explanation

The relationship between the numbers in the given sets is based on multiplication by 2. Each number in the set is doubled to obtain the next number.

In the first set: 59 × 2 = 118 118 × 2 = 236

In the second set: 64 × 2 = 128 128 × 2 = 256

Applying this same logic of multiplying by 2: 82 × 2 = 164 164 × 2 = 328

Explanation

The words Factory, Garage, and Casino represent physical locations, venues, or establishments where activities take place, whereas the words in all other groups represent professions, occupations, or human roles.

Explanation

The numbers in the given sets follow a specific mathematical pattern. In the set (a, b, c), the second number is twice the first number, and the third number is three more than the second number.

This relationship can be represented by the following formulas: b = a × 2 c = b + 3

Applying this pattern to the given sets: In (39, 78, 81): 39 × 2 = 78 78 + 3 = 81

In (42, 84, 87): 42 × 2 = 84 84 + 3 = 87

Applying this same logic to the correct set (84, 168, 171): 84 × 2 = 168 168 + 3 = 171

Explanation

The relation in the statement can be broken down step-by-step from Priya's perspective: Priya's brother's only son is Priya's nephew. The mother of Priya's brother's only son is her brother's wife. Therefore, the lady in the photo is Priya's brother's wife.

Explanation

The numbers in each set (A, B, C) follow the mathematical pattern where the second number is B = 4A - 3 and the third number is C = 4B + 3.

Applying this pattern to the given sets:

For the first set (18, 69, 279): 4 × 18 - 3 = 72 - 3 = 69 4 × 69 + 3 = 276 + 3 = 279

For the second set (12, 45, 183): 4 × 12 - 3 = 48 - 3 = 45 4 × 45 + 3 = 180 + 3 = 183

Applying the same pattern to the set (32, 125, 503): 4 × 32 - 3 = 128 - 3 = 125 4 × 125 + 3 = 500 + 3 = 503

Explanation

The coding scheme involves reversing the letters of the word and then adding +2 and +1 alternately to their alphabetical positions.

Reversing the word BOWLER gives RELWOB. Applying the pattern: R (18) + 2 = T (20) E (5) + 1 = F (6) L (12) + 2 = N (14) W (23) + 1 = X (24) O (15) + 2 = Q (17) B (2) + 1 = C (3) This results in the code TFNXQC.

Applying the identical logic to the word BOWMAN: First, reverse the letters of BOWMAN to get NAMWOB. Then, apply the alternating +2 and +1 pattern to the letter positions: N (14) + 2 = P (16) A (1) + 1 = B (2) M (13) + 2 = O (15) W (23) + 1 = X (24) O (15) + 2 = Q (17) B (2) + 1 = C (3)

This yields the code PBOXQC.

Explanation

The relationship followed in the given pairs is: (First number × 2) + 2 = Second number

For the first pair: (38 × 2) + 2 = 76 + 2 = 78

For the third pair: (46 × 2) + 2 = 92 + 2 = 94

Applying the same relationship to the second pair: (102 × 2) + 2 = 204 + 2 = 206

Explanation

The relationship in the first pair is Capital : Country, as Nairobi is the capital city of Kenya. Following the same logic, Oslo is the capital city of Norway.

Explanation

In the word pairs Pencil-Stationery, Circle-Figure, and Truck-Vehicle, the first word represents a specific item that belongs to the general category represented by the second word. In the pair Animal-Cat, this relationship is reversed, as the first word represents the general category and the second word represents the specific item belonging to that category.

Explanation

The logical and meaningful sequence begins with a person experiencing an illness, which prompts them to visit a doctor. Upon meeting the doctor, they undergo a consultation. Following the consultation, the person goes to a dispensary to obtain the prescribed medicine. This step-by-step progression of events is Illness (1) → Doctor (3) → Consultation (5) → Dispensary (2) → Medicine (4), which corresponds to the sequence 1, 3, 5, 2, 4.

Explanation

The coding scheme calculates the product of the number of letters in the two words on either side of the asterisk operator.

For 'FAMILY * LONG': Number of letters in FAMILY = 6 Number of letters in LONG = 4 Product = 6 × 4 = 24

For 'COUPLE * THE': Number of letters in COUPLE = 6 Number of letters in THE = 3 Product = 6 × 3 = 18

Applying the same logic to 'OVER * HOSPITAL': Number of letters in OVER = 4 Number of letters in HOSPITAL = 8 Product = 4 × 8 = 32

Explanation

The relation between the numbers is defined by the formula: 2 × (first number + second number)

Applying this to the first equation: 2 × (8 + 6) = 2 × 14 = 28

Applying this to the second equation: 2 × (7 + 4) = 2 × 11 = 22

Using the same formula for the required expression: 2 × (9 + 3) = 2 × 12 = 24

Explanation

The letters in UVTX have alphabetical positions of 21, 22, 20, and 24. This represents positional differences of +1 from U to V, -2 from V to T, and +4 from T to X. In all other groups, the differences between consecutive letters are +1, -2, and +3, which would make the expected sequence UVTW. Therefore, UVTX is the odd group as it does not follow this common pattern.

Explanation

The relationship in the first pair is based on an object and its primary material, as a wall is constructed from bricks. Applying the same logic to the second pair, a sack is manufactured from jute.

Explanation

The given series is an arithmetic progression where each consecutive term is obtained by adding a constant difference of 10 to the preceding term.

Using the formula for the nth term of an arithmetic progression: aₙ = a + (n - 1)d

Here, the first term a is 17 and the common difference d is 10. For the 7th term, where n = 7: a₇ = 17 + (7 - 1) × 10 a₇ = 17 + 6 × 10 a₇ = 17 + 60 a₇ = 77

Explanation

Evaluating Equation I by interchanging the + and - signs: 11 + 16 × 3 - 4 - 12 = 11

Applying BODMAS rules, perform multiplication first: 16 × 3 = 48

Then perform addition and subtraction: 11 + 48 - 4 - 12 = 43

Since 43 is not equal to 11, Equation I is incorrect.

Evaluating Equation II by interchanging the + and - signs: 15 × 3 + 45 ÷ 5 - 30 = 28

Applying BODMAS rules, perform division first: 45 ÷ 5 = 9

Next, perform multiplication: 15 × 3 = 45

Then perform addition and subtraction: 45 + 9 - 30 = 24

Since 24 is not equal to 28, Equation II is also incorrect.

Explanation

According to the second statement, some T are P. In syllogisms, the converse of a particular affirmative statement of the form "Some A are B" is always true, which is "Some B are A". Therefore, from the statement "Some T are P", we can directly and definitely conclude that "Some P are T". This makes conclusion I logically valid.

Explanation

The relationship between the two numbers in each pair is defined by subtracting the second number from the first. For three of the pairs, this operation yields a constant difference of 2: 14 - 12 = 2 15 - 13 = 2 20 - 18 = 2

In the case of 25 - 19, the subtraction yields 6, which deviates from the common difference of 2 shared by all other pairs. Therefore, this pair is the odd one out.

Explanation

Each letter in the terms follows a distinct mathematical pattern based on its alphabetical position:

The first letter of each term increases by 6 positions: P (16) → V (22) → B (2) → H (8) → N (14).

The second letter of each term decreases by 3 positions: Q (17) → N (14) → K (11) → H (8) → E (5).

The third letter of each term increases by 8 positions: R (18) → Z (26) → H (8) → P (16) → X (24).

The fourth letter of each term decreases by 1 position: S (19) → R (18) → Q (17) → P (16) → O (15).

Applying these transitions to the last term yields the letters N, E, X, and O.

Explanation

The relationship established in the first pair is Currency : Country, as the Yen is the official currency of Japan. Following this same logic, the Lira is the official currency of Turkey.

Explanation

The operator in the given expression represents the subtraction operation, meaning x # y # z = x - y - z.

For the first equation: 64 - 58 - 32 = 6 - 32 = -26

For the second equation: 104 - 17 - 89 = 87 - 89 = -2

Applying the same mathematical logic to the target equation: 56 - 7 - 24 = 49 - 24 = 25

Explanation

The code for each word is obtained by multiplying the alphabetical positional values of its individual letters.

For DO: D = 4 O = 15 Product = 4 × 15 = 60

For PIE: P = 16 I = 9 E = 5 Product = 16 × 9 × 5 = 720

For CAT: C = 3 A = 1 T = 20 Product = 3 × 1 × 20 = 60

Explanation

The relationship in the given pair is Place of Work : Worker. An Engineer works at a Site. Similarly, a Servant works in a House, maintaining the exact same relationship and order.

Explanation

The given word pair exhibits the relationship of Country : Capital, as Thimphu is the capital of Bhutan. In the same way, Islamabad is the capital of Pakistan, maintaining the identical Country : Capital relationship.

Explanation

Statement II states that All windows are broken. In classical deductive logic, the universal proposition All A are B can be converted to the particular proposition Some B are A. Therefore, if all windows are broken, it logically follows that Some broken are windows. This makes Conclusion I valid. Since there is no logical connection established in the statements between windows and painted, Conclusion II cannot be deduced.

Explanation

To arrange the words in alphabetical dictionary order, we first look at the common prefix. All five words start with the prefix activ. We then compare the remaining letters of each word:

Activate has the suffix ate. Activism has the suffix ism. Activist has the suffix ist. Activist has the suffix ist. Activity has the suffix ity.

Comparing these suffixes alphabetically: The suffix ate starts with a, so Activate comes first. Comparing ism, ist, and ity, we look at the letter following i. Since s comes before t, both ism and ist come before ity. Comparing ism and ist, m comes before t, so Activism comes before Activist. Thus, Activist occupies the third and fourth positions. Lastly, Activity, which has the suffix ity, comes fifth.

The complete alphabetical order is: Activate Activism Activist Activist Activity

The word at the fourth position is Activist.

Explanation

Correct Answer: D

To determine which equations are not correct after interchanging + and -, each equation is solved using the BODMAS rule.

For Equation I, interchanging + and - gives: 18 - 3 - 8 × 5 + 4

Applying multiplication first: 18 - 3 - 40 + 4

Performing subtraction and addition: 15 - 40 + 4 = -21

Since -21 is not equal to 20, Equation I is not correct.

For Equation II, interchanging + and - gives: 6 - 8 × 9 - 3 + 4

Applying multiplication first: 6 - 72 - 3 + 4

Performing subtraction and addition: -66 - 3 + 4 = -65

Since -65 is not equal to 14, Equation II is also not correct.

Both equations I and II are incorrect after the interchange.

Explanation

The coding scheme follows an alternating pattern of adding 2 to the position of the odd-positioned letters and subtracting 2 from the position of the even-positioned letters.

Applying this to CEMENT: C + 2 = E E - 2 = C M + 2 = O E - 2 = C N + 2 = P T - 2 = R This gives ECOCPR.

Applying this to HEIGHT: H + 2 = J E - 2 = C I + 2 = K G - 2 = E H + 2 = J T - 2 = R This gives JCKEJR.

Following the same pattern for FATHER: F + 2 = H A - 2 = Y T + 2 = V H - 2 = F E + 2 = G R - 2 = P This yields HYVFGp.

Explanation

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

Second number = First number × 5.5

Applying this formula to the given pairs:

58 × 5.5 = 319

32 × 5.5 = 176

76 × 5.5 = 418

Explanation

In the number pair 126215 - 25247, the left number is not equal to 5 times the right number, as 25247 × 5 = 126235. In the other pairs, the number on the left is exactly 5 times the number on the right.
