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

Explanation

The logic of the analogy follows a specific shift in the alphabetical positions of the letters. The first letter is shifted forward by 7 positions (+7) and the second letter is shifted backward by 7 positions (-7).

For the first pair, ST to ZM: S is the 19th letter, and 19 + 7 = 26, which is Z. T is the 20th letter, and 20 - 7 = 13, which is M.

Applying this same logic to KR: K is the 11th letter, and 11 + 7 = 18, which is R. R is the 18th letter, and 18 - 7 = 11, which is K.

Explanation

The relationship between the first pair of numbers is based on the cubing operation, where the second number is the cube of the first number.

3³ = 3 × 3 × 3 = 27

Applying the same logic to the second pair, we cube the number 4 to find the missing term:

4³ = 4 × 4 × 4 = 64

Explanation

Oil is a fat substance derived primarily from plants, seeds, or minerals and is not a dairy product.

Explanation

The letter pair PR is composed entirely of consonants, containing no vowels. Every other letter pair in the alternatives contains exactly one vowel (A in LA, O in OC, and U in US). Since PR is the only letter pair without a vowel, it is the odd one out.

Explanation

The number 64 is both a perfect square (8²) and a perfect cube (4³), unlike the other numbers in the set which are only perfect cubes.

Explanation

For the standard numbers in this set, the first digit is equal to the sum of the second and third digits. This is seen in 844 where 8 = 4 + 4, in 972 where 9 = 7 + 2, and in 716 where 7 = 1 + 6. In the case of 345, the first digit 3 is not equal to the sum of the other two digits, which is 4 + 5 = 9.

Explanation

The series lists the Prime Ministers of India in chronological order of their assumption of office. Jawaharlal Nehru served as the first Prime Minister of India from 1947 to 1964, immediately preceding Lal Bahadur Shastri, who served from 1964 to 1966. This is followed in sequence by Indira Gandhi, Morarji Desai, and Choudhary Charan Singh.

Explanation

The series is formed by two independent patterns for the first and second letters of each term.

The first letter of each term increases by two positions in alphabetical order: V (22) + 2 = X (24) X (24) + 2 = Z (26) Z (26) + 2 = B (2) B (2) + 2 = D (4)

The second letter of each term decreases by two positions in alphabetical order: W (23) - 2 = U (21) U (21) - 2 = S (19) S (19) - 2 = Q (17) Q (17) - 2 = O (15)

Combining these two letters gives the next term in the series as DO.

Explanation

The given series follows a consistent pattern where the alphabetical position of each letter increases by 3 in successive terms.

By analyzing the first letter of each term: A (+3) → D (+3) → G (+3) → J (+3) → M

By analyzing the second letter of each term: N (+3) → Q (+3) → T (+3) → W (+3) → Z

Combining the two letters yields MZ.

Explanation

The given series is based on adding consecutive multiples of 25 to each preceding term.

101 - 76 = 25 151 - 101 = 50 226 - 151 = 75

The differences between successive terms are 25, 50, and 75, which increase by 25 at each step. Following this pattern, the next difference must be 100.

226 + 100 = 326

Explanation

The first statement highlights that students are performing poorly in Political Science compared to other subjects, as evidenced by a very low pass percentage. The second statement explains that these students did not have prior exposure to Political Science before joining the programme. By combining these two facts, a direct causal relationship can be inferred: the lack of previous study (absence of a foundation) has led to poor performance in the examinations. Therefore, having a prior foundation in the subject is crucial for a student to perform well in the exam, which makes the first conclusion logically valid.

Explanation

The month of April has exactly 30 days. The number of days between April 1st and May 1st is 30. Dividing 30 by 7 to determine the number of odd days gives a quotient of 4 weeks and a remainder of 2 odd days, since 30 = 4 × 7 + 2. Adding these 2 odd days to Wednesday (Wednesday + 2 days) results in Friday.

Explanation

Comparing the given words alphabetically, we compare each letter from left to right.

First, we compare Training (iii) and Translate (iv). Both begin with Tra. Since the fourth letter i in Training comes before n in Translate, Training (iii) is placed before Translate (iv).

Next, we compare Treadmill (ii) and Treasure (i). Both begin with Trea. Since the fifth letter d in Treadmill comes before s in Treasure, Treadmill (ii) is placed before Treasure (i).

Combining these, the words beginning with Tra come before the words beginning with Tre. Therefore, the alphabetical sequence of the words is Training (iii), Translate (iv), Treadmill (ii), and Treasure (i).

Explanation

The coding pattern involves reversing the order of the letters of the given word and then shifting each letter backward by one position in the alphabetical order.

Applying this pattern to VERBAL: Reversing the word VERBAL gives LABREV. Subtracting 1 from the alphabetical position of each letter: L - 1 = K A - 1 = Z B - 1 = A R - 1 = Q E - 1 = D V - 1 = U This results in KZAQDU.

Applying the same pattern to CURIOUS: Reversing the word CURIOUS gives SUOIRUC. Subtracting 1 from the alphabetical position of each letter: S - 1 = R U - 1 = T O - 1 = N I - 1 = H R - 1 = Q U - 1 = T C - 1 = B

This results in the coded word RTNHQTB.

Explanation

The pattern in each column of the matrix is that the product of the number in the first row and the number in the third row equals the number in the second row.

Row 1 × Row 3 = Row 2

Applying this pattern to the second column: 12 × 9 = 108

Applying this pattern to the third column: 9 × 8 = 72

Using the same pattern for the first column: ? × 9 = 36 ? = 36 ÷ 9 ? = 4

Explanation

Substituting the given operators in place of the letters: A represents + B represents ÷ C represents × D represents -

The expression 180 B 36 C 5 A 8 D 32 is rewritten as: 180 ÷ 36 × 5 + 8 - 32

Applying the order of operations (BODMAS rule): First, perform the division: 180 ÷ 36 = 5 Next, perform the multiplication: 5 × 5 = 25 Then, perform the addition: 25 + 8 = 33 Finally, perform the subtraction: 33 - 32 = 1

Explanation

The letter series is based on the repetition of a 6-letter pattern: KKLLLL.

Dividing the series into blocks of 6 letters helps identify the repeating structure: KK_LL_ / K_L_LL

By sequentially placing the letters L, L, K, and L into the four respective gaps: The first gap is filled with L, making the first block KKLLLL. The second gap is filled with L, completing the first block KKLLLL. The third gap is filled with K, starting the second block as KKLL... The fourth gap is filled with L, completing the second block as KKLLLL.

This completes the perfect repeating sequence: KKLLLL KKLLLL

Explanation

Directional vectors from one point to another are always directly opposite when the reference point is reversed. The opposite of the North direction is South, and the opposite of the East direction is West. Combining these, the exact opposite of the North-East direction is South-West. Since Rahul's school is located in the North-East direction from his house, looking from the school back to the house is looking in the opposite direction, which is South-West.

Explanation

The letters of the word SURE can be represented using the row-by-column format from Matrix-I and Matrix-II.

For the letter S, looking at Matrix-II, we locate it at row 5 and column 6, which gives the number 56.

For the letter U, looking at Matrix-I, we find it at row 1 and column 0, giving the number 10.

For the letter R, looking at Matrix-II, it is located at row 8 and column 9, giving the number 89.

For the letter E, looking at Matrix-I, it is located at row 3 and column 0, giving the number 30.

Combining these coordinates gives the sequence 56, 10, 89, 30.

Explanation

Analyze the relationship step by step:

The phrase "your father's wife" refers directly to the girl's mother.

The phrase "the only daughter of my maternal grandmother" refers to the boy's own mother, because his maternal grandmother is his mother's mother, and she has only one daughter.

Equating the two relationships, the girl's mother is the same person as the boy's mother. Since they share the same mother, the boy is the brother of the girl.

Explanation

Zoology is the branch of biology that deals with the study of animals. In the same way, virology is the scientific study of viruses and virus-like agents, including their structure, classification, and evolution.

Explanation

The letters of the first word PLUMBER are written in the reverse order to obtain the second term REBMULP. Following the same logic, reversing the letters of LABREV from right to left yields the word VERBAL.

Explanation

The relationship between the letters is based on opposite alphabetical positions, where the sum of the numerical positions of the corresponding letters from the start and the end of the alphabet is 27.

In the first group Hi, the letter H is the 8th letter from the beginning, and its opposite is S, which is the 19th letter (8 + 19 = 27). The letter i is the 9th letter from the beginning, and its opposite is r, which is the 18th letter (9 + 18 = 27). This gives the pair Sr.

Applying this same logic to Fg, the letter F is the 6th letter from the beginning, so its opposite must be the 21st letter, which is U (6 + 21 = 27). The letter g is the 7th letter from the beginning, so its opposite must be the 20th letter, which is t (7 + 20 = 27). Keeping the pattern of uppercase followed by lowercase, we get Ut.

Explanation

The relationship between the numbers in each pair follows the pattern n : n(n + 1).

For the first pair, the calculation is 11 × (11 + 1) = 11 × 12 = 132.

Applying the same pattern to the second pair with n = 12, the calculation is 12 × (12 + 1) = 12 × 13 = 156.

Explanation

Praise is the odd word because it means to express warm approval, admiration, or commendation. It represents a positive action, which is the direct opposite of the other terms that all convey disapproval, blame, or censure.

Explanation

Converting the letters to their alphabetical positions where A = 1, B = 2, and so on, the sum of the numerical values of the letters in BC is 2 + 3 = 5, whereas the sum of the numerical values of the letters in each of the other options is 15.

Explanation

In the given set of numbers, the product of the first two digits is equal to the number formed by the last two digits. This pattern is followed by 2714 (2 × 7 = 14), 8432 (8 × 4 = 32), and 6742 (6 × 7 = 42). For 7858, the product of the first two digits is 7 × 8 = 56, which does not equal 58.

Explanation

The sum of the digits of the number 745 is 7 + 4 + 5 = 16, which is not divisible by 3. For the other three numbers, the sum of the digits is 21 (6 + 8 + 7 = 21, 7 + 7 + 7 = 21, and 9 + 9 + 3 = 21), making them all divisible by 3.

Explanation

The series represents the ascending hierarchy of commissioned officer ranks in the Indian Air Force. The rank structure in ascending order begins with Flying Officer, which is followed by Flight Lieutenant, Squadron Leader, and Wing Commander. Thus, Flying Officer is the missing rank that completes the series.

Explanation

The series is formed by multiplying each term by consecutive integers starting from 2:

12 × 2 = 24 24 × 3 = 72 72 × 4 = 288

Following this logic, the next term is obtained by multiplying the fourth term by 5:

288 × 5 = 1440

Explanation

According to the given statements, major companies survive nowadays due to a strong supply chain system, which is comprised of logistics, retailers, and distributors.

Conclusion II logically follows because logistics is established as a vital component of the supply chain system. Having strong logistics directly reinforces the overall supply chain, which ensures that products are made easily available to customers, enabling companies to survive in the current competitive environment implied by the word nowadays.

Conclusion I does not follow because the statements only list retailers as one of the components of the supply chain. The statements do not provide any hierarchical information or comparison to suggest that retailers play the most important role compared to logistics or distributors.

Explanation

The series is formed by two independent patterns for the first and second letters of each term.

The first letter of each term increases by one position in alphabetical order: F (+1) → G (+1) → H (+1) → I. The next letter in this sequence is J.

The second letter of each term decreases by one position in alphabetical order: U (-1) → T (-1) → S (-1) → R. The next letter in this sequence is Q.

Additionally, the letters in each pair are alphabetical opposites where the position from the start of the alphabet matches the position from the end. Following these patterns yields the next term as JQ.

Explanation

The series follows a pattern based on the position of the letters in the English alphabet, where A = 1, B = 2, and so on up to Z = 26.

The first letter of each term increases by a progressively larger increment: From O (15) to R (18), the increment is +3. From R (18) to V (22), the increment is +4. Following this pattern, the first letter of the missing term is V (22) + 5 = 27, which cyclically wraps around to A (1). To verify, from A (1) to G (7), the increment is +6, confirming the sequence of increments is +3, +4, +5, +6.

The second letter in each term is always the consecutive alphabet immediately following the first letter: O is followed by P. R is followed by S. V is followed by W. A is followed by B, making the missing term AB. G is followed by H.

Explanation

Ankit's total marks obtained in the three subjects are calculated by summing his individual scores: 32 + 45 + 49 = 126

Since the maximum marks for each of the three subjects is 50, the total maximum marks are: 50 × 3 = 150

His overall percentage is the ratio of total marks obtained to total maximum marks, expressed as a percentage: (126 / 150) × 100 = 84%

Explanation

To arrange the words in alphabetical order as they would appear in a dictionary, we compare them letter by letter from left to right. All four words share the same prefix Prema. Next, we compare the sixth letter of each word:

In Premake (iii), the sixth letter is k. In Premalignant (ii), the sixth letter is l. In Premanifest (i), the sixth letter is n. In Premarital (iv), the sixth letter is r.

Arranging these letters alphabetically gives k, l, n, and r. Consequently, the correct sequence is Premake, Premalignant, Premanifest, and Premarital, which corresponds to the order iii, ii, i, iv.

Explanation

The coding pattern involves shifting each letter of the word forward by two positions in alphabetical order.

Applying this +2 shift rule to the letters of the word MOBILE: M + 2 = O O + 2 = Q B + 2 = D I + 2 = K L + 2 = N E + 2 = G

Applying the exact same pattern to the word RANGER: R + 2 = T A + 2 = C N + 2 = P G + 2 = I E + 2 = G R + 2 = T

This yields the coded word TCPIGT.

Explanation

In this matrix, the sum of the numbers in each column is constant and equals 90.

For the first column: 16 + 36 + 38 = 90

For the second column: 49 + 25 + 16 = 90

Following the same logic for the third column: 64 + 6 + ? = 90 70 + ? = 90 ? = 20

Explanation

Using the BODMAS rule (Brackets, Orders, Division, Multiplication, Addition, Subtraction), we substitute the given letter codes with their corresponding mathematical operators:

C denotes - D denotes + B denotes ÷ A denotes ×

Substituting these into the given expression:

76 - 54 + 210 ÷ 3 × 15

First, perform the division operation: 210 ÷ 3 = 70

The expression becomes: 76 - 54 + 70 × 15

Next, perform the multiplication operation: 70 × 15 = 1050

The expression becomes: 76 - 54 + 1050

Finally, perform the subtraction and addition from left to right: 22 + 1050 = 1072

Explanation

The letter series forms a repeating pattern of the four-letter group "jklm":

jklm / jklm / jklm

By sequentially placing the letters of the set "kmljm" into the blanks of the series "j_l_jk_m_kl_", we get:

j [k] l [m] j k [l] m [j] k l [m]

This completes the repeating "jklm" sequence.

Explanation

Karan's path forms three sides of a rectangle. Starting from the origin, going 20 km south reaches a point. Turning left means going east for 35 km, and turning left again means going north for 20 km. Since the southward and northward journeys are of equal length (20 km), they cancel each other out vertically. The final position lies directly east of the starting position, separated only by the horizontal distance of 35 km.

Explanation

According to the instructions, each letter is represented first by its row number and then by its column number.

To represent the word GRIM: The letter G is located in Matrix-I at row 2 and column 3, which is written as 23. The letter R is located in Matrix-II at row 5 and column 7, which is written as 57. The letter I is located in Matrix-I at row 1 and column 1, which is written as 11. The letter M is located in Matrix-II at row 8 and column 8, which is written as 88.

Combining these representation codes in sequence gives 23, 57, 11, 88.

Explanation

To determine the relationship, the statement is broken down starting from the end of the phrase: The daughter of Amarjeet's father is Amarjeet's sister. The son of Amarjeet's sister is Amarjeet's nephew. Thus, the boy is the nephew of Amarjeet.

Explanation

The relationship between the first pair is that of synonyms, as both pardon and exonerate mean to free from blame or forgive an offense. Following the same pattern, a connoisseur is a person who has expert knowledge or a refined taste in a particular field, making specialist the synonymous term that completes the analogy.

Explanation

The relationship between the letter pairs is based on the positions of the letters in the English alphabet.

In the second pair BC : HJ: B is the 2nd letter and H is the 8th letter, representing an increase of 6 positions (2 + 6 = 8). C is the 3rd letter and J is the 10th letter, representing an increase of 7 positions (3 + 7 = 10).

Applying the same pattern to the first pair ? : KM, where K is the 11th letter and M is the 13th letter: The first letter of the missing term must be 6 positions before K, which is 11 - 6 = 5. The 5th letter of the alphabet is E. The second letter of the missing term must be 7 positions before M, which is 13 - 7 = 6. The 6th letter of the alphabet is F.

Explanation

By mapping the letters to their alphabetical positions, D is 4, E is 5, L is 12, and M is 13. Comparing the first pair, the relationship is a constant addition of 8 positions to each letter, since 4 + 8 = 12 and 5 + 8 = 13.

Applying this same relationship to find the missing letters before PQ, where P is 16 and Q is 17: The first letter is 16 - 8 = 8, which is H. The second letter is 17 - 8 = 9, which is I.

This yields the letters HI.

Explanation

The given numbers follow the rule of direct proportion, represented as: a : b :: c : d

This relationship can be expressed with the formula: d = (b × c) / a

Substituting the given values, where a = 2, b = 14, and c = 21: d = (14 × 21) / 2 d = 7 × 21 d = 147

Explanation

Fraternity represents a state of brotherhood, harmony, and mutual cooperation, which denotes peace and social order. The other terms in the group denote situations of chaos, disruption, and political upheaval.

Explanation

In the pair EV, the alphabetical position of the first letter E is 5, and the position of the second letter V is 22. This deviates from the consistent pattern of the other pairs, where the position of the second letter is exactly twice the position of the first letter. For the letter E, twice its positional value is 5 × 2 = 10, which corresponds to J, not V.

Explanation

The classification of the given numbers is based on their divisibility by 11.

The numbers 2310, 1430, and 1518 are all perfectly divisible by 11: 2310 ÷ 11 = 210 1430 ÷ 11 = 130 1518 ÷ 11 = 138

For these numbers, the divisibility rule of 11 holds true. This rule states that if the difference between the sum of digits at odd positions and the sum of digits at even positions is either 0 or a multiple of 11, then the number is divisible by 11.

Applying this rule to the number 1656: Sum of digits at odd positions (first and third digits) = 1 + 5 = 6 Sum of digits at even positions (second and fourth digits) = 6 + 6 = 12 The difference between the two sums is 12 - 6 = 6, which is not divisible by 11.

Thus, 1656 is not divisible by 11 (1656 ÷ 11 = 150.54), making it the odd number among the choices.

Explanation

In the number 111, the subtraction of the second digit from the first digit does not equal the third digit since 1 - 1 = 0, which is not equal to 1. Additionally, 111 is an odd number.
