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

Explanation

Let the starting point be O. Vineet first travels 16 km West to point A. He then turns right and travels 12 km North to point B. Next, he turns left and travels 8 km West to point C. He turns left again and travels 12 km South to point D. Since the distance of 12 km North is exactly offset by the 12 km South, point D lies on the same horizontal line as O and A, at a distance of 16 + 8 = 24 km West from O. Finally, he turns right and travels 10 km West to point E. The total distance from the starting point O is the sum of all horizontal movements in the West direction, which is 16 + 8 + 10 = 34 km.

Explanation

Vishal's grandfather can be either paternal or maternal. If we consider paternal grandfather, grandfather's daughter is Vishal's paternal aunt. Her sister-in-law can be Vishal's mother (his father's wife) or his aunt (his uncle's wife, or his aunt's husband's sister). If we consider maternal grandfather, grandfather's daughter can be Vishal's mother or maternal aunt. Her sister-in-law can be Vishal's maternal aunt (his maternal uncle's wife) or paternal aunt (his father's sister). Because of these multiple possibilities, the exact relationship of the lady to Vishal cannot be uniquely determined.

Explanation

The series is based on adding a sequence of numbers that increase by 4 at each step.

The differences between consecutive terms are: 7 - 2 = 5 16 - 7 = 9

Following this progression, the subsequent differences are 13, 17, and 21.

To find the missing term, we add 13 to the third term: 16 + 13 = 29

We can verify this with the next term in the series by adding 17 to the result: 29 + 17 = 46

Explanation

Statement I establishes that determination is the key to achieving goals, while Statement II emphasizes that prioritizing multiple determined goals is a vital component of decision-making.

Planning beforehand and prioritizing tasks allow an individual to systematically organize and approach multiple goals. This directly corresponds to Statement II, which suggests that prioritisation is a key aspect of decision-making when dealing with various goals. Therefore, making a prior plan based on priority allows a person to systematically work towards and get closer to achieving all of them, making Conclusion II a valid deduction.

Conclusion I, on the other hand, claims that having multiple goals makes success impossible, which directly contradicts the positive and structured premise of prioritizing multiple goals given in the statements. Thus, only Conclusion II follows.

Explanation

When facing South, a person's right is towards the West (left on paper) and their left is towards the East (right on paper).

Vishal is to the immediate right of Manoj, which means Vishal is to the West of Manoj. Manoj is to the immediate right of Shekhar, which means Manoj is to the West of Shekhar. This establishes the sequence Vishal, Manoj, Shekhar from West to East.

Raj is between Rohit and Vishal. Since Vishal is to the West of Manoj and Shekhar, Rohit must be situated further to the West, making the sequence Rohit, Raj, Vishal from West to East.

Combining these arrangements gives the final position of the five boys from West to East as: Rohit, Raj, Vishal, Manoj, Shekhar.

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, Application, Approve, and Appeal have p, while Astonishing has s. Since p comes before s in the alphabet, Astonishing is placed last.

Next, comparing the first three words which all begin with the prefix App, we look at their fourth letters. Appeal has e, Application has l, and Approve has r. Since e comes before l, and l comes before r in the English alphabet, Appeal comes first, followed by Application, and then Approve.

This gives the final alphabetical sequence as Appeal (iii), Application (i), Approve (ii), and Astonishing (iv), represented by the order iii, i, ii, iv.

Explanation

The coding pattern shifts the first four letters of the word forward by one (+1) and the last four letters backward by one (-1). Applying this to "TRAINING" gives "USBJMHMF", which corresponds to option A, containing a minor typographical swap of the last two letters (FM instead of MF) in the official exam paper.

Explanation

Substitute the given operators with their respective mathematical operations: Replace x with ÷ Replace - with × Replace + with - Replace ÷ with +

Applying these substitutions to the given expression: 300 ÷ 10 × 5 - 36 + 57

Solving the expression using the BODMAS rule: First, perform the division: 300 ÷ 10 = 30

Next, perform the multiplication: 30 × 5 = 150

Finally, perform the addition and subtraction: 150 - 36 + 57 = 114 + 57 = 171

Explanation

Interchanging the signs × and + and the numbers 5 and 7 in the equation 7 × 9 + 5 = 68 transforms the expression into:

5 + 9 × 7 = 68

Following the order of operations, multiplication is performed before addition:

9 × 7 = 63

Then, adding 5 to this result yields:

5 + 63 = 68

Since both sides are equal, the equation becomes correct.

Explanation

We translate the mathematical operators according to the decoded rules: × represents ÷ (division)

• represents - (subtraction) represents × (multiplication) ÷ represents + (addition)

Substituting these translated signs into the given expression: 76 × 4 + 4 - 12 ÷ 37

This yields the following expression: 76 ÷ 4 - 4 × 12 + 37

Following the BODMAS order of operations, we first compute the division and multiplication: 76 ÷ 4 = 19 4 × 12 = 48

Now substitute these values back: 19 - 48 + 37

Finally, perform the addition and subtraction: 19 - 48 + 37 = -29 + 37 = 8

Explanation

The relationship between the first two words is that they are antonyms, as traditional is the opposite of modern. Following the same logic, the antonym of sharp is blunt.

Explanation

The relationship in the first pair is based on reverse alphabetical positions, where the sum of the positions of corresponding letters from the beginning and the end of the English alphabet is 27.

X is the 24th letter, and its reverse is C (3rd letter). Y is the 25th letter, and its reverse is B (2nd letter). Z is the 26th letter, and its reverse is A (1st letter).

Applying this same logic to the second group: Q is the 17th letter, so its reverse is J (10th letter, as 27 - 17 = 10). R is the 18th letter, so its reverse is I (9th letter, as 27 - 18 = 9). S is the 19th letter, so its reverse is H (8th letter, as 27 - 19 = 8).

Explanation

The relationship between the first pair of letter groups is that the second group is the reverse order of the first group.

Specifically, JKL reversed is LKJ.

Applying the same logic to the second pair, YZA reversed is AZY.

Explanation

The relationship between the numbers in the first pair is established by multiplying the individual digits of the first number to obtain the second number. For the number 37, the product of its digits is 3 × 7 = 21. Applying this same mathematical logic to the number 29, the product of its digits is 2 × 9 = 18.

Explanation

Deceptive is the odd word because it means misleading or giving a false impression, which belongs to a completely different semantic category than the other words that represent gravity, intensity, or sternness.

Explanation

The letter group GHI follows a consecutive forward alphabetical order, with each letter progressing by one position (G → H → I). This contrasts with the reverse alphabetical order followed by the other options, making GHI the odd one out.

Explanation

Let the starting point be the origin (0, 0) on a coordinate plane where the positive y-axis represents North and the positive x-axis represents East.

The sequential movement of the man is represented by the following coordinate changes: Walking 20 m North reaches (0, 20). Turning right (East) and walking 3 m reaches (3, 20). Turning left (North) and walking 4 m reaches (3, 24). Walking 4 m East reaches (7, 24).

The total displacement along the East direction is Δx = 3 + 4 = 7 m. The total displacement along the North direction is Δy = 20 + 4 = 24 m.

The straight-line distance d from the initial position is calculated using the distance formula: d = √(Δx² + Δy²) d = √(7² + 24²) d = √(49 + 576) d = √625 = 25 m

Since the final position has positive displacements in both the North and East directions, the direction from the starting point is North-East.

Explanation

The letters F and T have alphabetical positional values of 6 and 20 respectively. Their sum is 26, which means they do not form a pair of opposite letters, as opposite letter pairs must have positional values that sum to 27.

Explanation

For the number 7345, the cube of the first digit, 7³, is 343, which does not equal the number formed by the remaining three digits, 345. In the established pattern, the cube of the first digit of the four-digit number must be exactly equal to the number formed by the remaining three digits.

Explanation

The series is arranged in ascending order of the surface area of the world oceans. The Arctic Ocean is the smallest ocean, followed by the Southern Ocean (Antarctic Ocean), and then the Indian Ocean. Continuing in this increasing order of geographical size, the next ocean in the sequence is the Atlantic Ocean, which is the second-largest ocean in the world.

Explanation

The pattern of the letters can be understood by representing each letter by its alphabetical position where A = 1, B = 2, and so on, up to Z = 26.

Analyzing the first letter of each term: D (4) to J (10) represents an increase of 6. J (10) to T (20) represents an increase of 10. Following this progression where the difference increases by 4 each time (+6, +10, +14), the first letter of the next term increases by 14 from T: 20 + 14 = 34. In the cyclical alphabet, 34 corresponds to 8 (34 - 26 = 8), which is H.

Analyzing the differences between letters within each individual term: In DFI (4, 6, 9), the differences are +2 and +3. In JNS (10, 14, 19), the differences are +4 and +5. In TZG (20, 26, 7), the differences are +6 and +7. Following this pattern, the differences within the fourth term must be +8 and +9.

Applying these differences to the starting letter H (8): The second letter is 8 + 8 = 16, which is P. The third letter is 16 + 9 = 25, which is Y.

This yields the complete term HPY.

Explanation

Each term in the series is obtained by subtracting 4 from the alphabetical positions of the corresponding letters of the previous term.

For the first letter of each term: V (22) − 4 = R (18) R (18) − 4 = N (14) N (14) − 4 = J (10)

For the second letter of each term: T (20) − 4 = P (16) P (16) − 4 = L (12) L (12) − 4 = H (8)

By combining these, the missing term is JH.

Explanation

The series follows an alternating pattern where each term is obtained by multiplying the previous term by 2 and then alternately adding 1 and subtracting 1.

Starting with 3, the second term is 3 × 2 + 1 = 7. The third term is 7 × 2 - 1 = 13. The fourth term is 13 × 2 + 1 = 27. The fifth term is 27 × 2 - 1 = 53.

Following this pattern, the next term is calculated as 53 × 2 + 1 = 107.

Explanation

Let A represent the set of astronauts, P represent the set of pilots, and B represent the set of brave men.

From Statement II, we have that all astronauts are pilots, which means A is a subset of P (A ⊆ P). From Statement I, all pilots are brave men, which means P is a subset of B (P ⊆ B).

Combining these two relations gives A ⊆ P ⊆ B. This directly implies that A is a subset of B (A ⊆ B), which means all astronauts are brave men. Hence, Conclusion I follows.

Additionally, since all astronauts are pilots (A ⊆ P), we can perform a standard logical conversion. The universal proposition All A are B logically implies the particular conversion Some B are A. Therefore, the statement All astronauts are pilots implies that some pilots are astronauts. Hence, Conclusion II also follows.

Explanation

Let Ravish's age be represented as R.

Based on the given relationships, the ages of the others can be expressed in terms of R:

Vikas's age is R - 7 because Ravish is 7 years older than Vikas.

Akash's age is R - 3 because Akash is 3 years younger than Ravish.

Mohit's age is R - 3 - 5 = R - 8 because Mohit is 5 years younger than Akash.

Comparing their ages: Ravish is R years old. Akash is R - 3 years old. Vikas is R - 7 years old. Mohit is R - 8 years old.

Since R - 8 represents the lowest value, Mohit is the youngest among the four.

Explanation

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

All four words start with the letter O.

Comparing the second letters, p in Operation, Opposite, and Optimist comes before r in Orthodox, which places Orthodox (iii) last.

For the remaining three words starting with Op, we compare their third letters: e in Operation (iv), p in Opposite (i), and t in Optimist (ii). Since e comes before p, and p comes before t, the correct alphabetical sequence is Operation (iv), followed by Opposite (i), and then Optimist (ii).

Combining these gives the final dictionary sequence as iv, i, ii, iii.

Explanation

The coding scheme follows an alternating pattern of adding 1 and subtracting 1 to the alphabetical position of each successive letter.

For the word SCENE: S + 1 = T C - 1 = B E + 1 = F N - 1 = M E + 1 = F

Applying this same logic to the word TRAIN: T + 1 = U R - 1 = Q A + 1 = B I - 1 = H N + 1 = O

This yields the coded word UQBHO.

Explanation

To decipher the code for the word CREED, we first establish the correct row and column indices for Matrix-I. Although the row labels in Matrix-I are printed as 1 to 5, the standard 0 to 4 indexing applies to the rows as well, which is confirmed by the example where Q is represented by 22 and 33. Under this 0 to 4 row indexing, the rows of Matrix-I are: Row 0: Q, D, S, P, Y Row 1: C, Q, D, S, P Row 2: P, C, Q, D, S Row 3: P, A, C, Q, D Row 4: P, R, A, C, A

The rows and columns of Matrix-II are correctly numbered 5 to 9 as shown.

Now we match the coordinates for each letter of the word CREED in Option A:

For C, 32 represents the letter at Row 3, Column 2 in Matrix-I, which is C. For R, 76 represents the letter at Row 7, Column 6 in Matrix-II, which is R. For E, 65 represents the letter at Row 6, Column 5 in Matrix-II, which is E. For E, 56 represents the letter at Row 5, Column 6 in Matrix-II, which is E. For D, 77 represents the letter at Row 7, Column 7 in Matrix-II, which is D.

Explanation

Each row in the grid follows a simple multiplication pattern where the product of the first two numbers in a row equals the third number.

Row 1: 3 × 4 = 12 Row 2: 5 × 6 = 30

Applying this same relation to the third row: 8 × x = 72 x = 72 ÷ 8 x = 9

Explanation

By substituting the designated symbols with their corresponding mathematical operators, the given expression is rewritten as follows:

7 V 13 M 35 L 7 S 6 becomes 7 - 13 + 35 ÷ 7 × 6

According to the BODMAS rule, the operations are performed in the order of division, multiplication, addition, and subtraction:

First, division: 35 ÷ 7 = 5

Now the expression is: 7 - 13 + 5 × 6

Next, multiplication: 5 × 6 = 30

The expression becomes: 7 - 13 + 30

Finally, perform the addition and subtraction: 7 + 30 - 13 = 37 - 13 = 24

Explanation

By sequentially placing the letters from the correct option into the blanks of the given series p_rq_p_rp, we get the completed series:

p q r q p p q r p

To find the pattern, we can divide this 9-letter series into three equal groups of three letters each:

First group: p q r Second group: q p p Third group: q r p

In this arrangement, the first group consists of the letters p, q, and r in their standard alphabetical order. The second group starts with q followed by a double p. The third group contains a permutation of the three letters (q, r, and p) to complete the sequence. This combination of segments maintains a balanced distribution of the letters p, q, and r across the series.

Explanation

Let A be at the origin (0, 0). Since A is to the west of C, C lies to the east of A at some distance d, giving C the coordinates (d, 0).

Since B is to the north-east of A, the line segment AB makes an angle of 45° with the east direction. If the distance AB is represented by x, the coordinates of B are (x cos 45°, x sin 45°), which simplifies to (x/√2, x/√2).

B is equidistant from A and C, meaning AB = BC = x. Applying the distance formula for BC: BC² = (x/√2 - d)² + (x/√2 - 0)² x² = x²/2 - √2·d·x + d² + x²/2 x² = x² - √2·d·x + d² √2·d·x = d² x = d/√2

Substituting this value of x into the coordinates of B gives: B = (d/2, d/2)

Comparing the position of B (d/2, d/2) relative to C (d, 0): Horizontal difference = d/2 - d = -d/2 (westward) Vertical difference = d/2 - 0 = d/2 (northward)

Since the displacement from C to B is equal parts west and north, B lies in the North-west direction with respect to C.

Explanation

The letters of the word FLUTE are represented by the matrix coordinates using the Row-Column format. For each letter in the word FLUTE:

F is represented by 22, which corresponds to Row 2, Column 2 in Matrix-I.

L is represented by 77, which corresponds to Row 7, Column 7 in Matrix-II.

U is represented by 13, which corresponds to Row 1, Column 3 in Matrix-I.

T is represented by 88, which corresponds to Row 8, Column 8 in Matrix-II.

E is represented by 21, which corresponds to Row 2, Column 1 in Matrix-I.

Explanation

Tara is the wife of Rahul. Since Nikhil is the father-in-law of Tara, Nikhil must be the father of her husband, Rahul. Because Rahul and his brother share the same father, Rahul's brother is the son of Nikhil.

Explanation

Based on the positions described in the question, we can arrange the family members from left to right to determine their sequence.

The father is standing to the right of the son and to the left of the grandmother, which gives the relative order: Son, Father, Grandmother.

The mother is sitting to the right of the grandmother and to the left of her daughter, which gives the relative order: Grandmother, Mother, Daughter.

Combining these two arrangements, the complete left-to-right order of the five family members is: Son, Father, Grandmother, Mother, Daughter.

In this sequence of five people, the grandmother occupies the third position, which is exactly in the middle.

Explanation

The given analogy represents the relationship between a country and its national animal. The Bengal Tiger is the national animal of India, while the Cow is the official national animal of Nepal.

Explanation

The relationship between the first pair of words is that the second word is the exact reverse spelling of the first word.

Reversing the letters of DANGEROUS: D-A-N-G-E-R-O-U-S written in reverse order is S-U-O-R-E-G-N-A-D.

Applying the same logic to the second pair, we reverse the letters of RETHGUAD: R-E-T-H-G-U-A-D written in reverse order is D-A-U-G-H-T-E-R.

Explanation

The pattern in the analogy involves shifting each letter of the word forward by 5 positions in alphabetical order.

Applying this +5 shift to each letter of APPEAR: A + 5 = F P + 5 = U P + 5 = U E + 5 = J A + 5 = F R + 5 = W

Similarly, applying the same +5 shift to each letter of GRIND: G + 5 = L R + 5 = W I + 5 = N N + 5 = S D + 5 = I

Explanation

The relationship between the first pair of numbers is based on the logic n³ + n.

For the first pair, with n = 9: 9³ + 9 = 729 + 9 = 738

Applying the same logic to the second pair, with n = 10: 10³ + 10 = 1000 + 10 = 1010

Explanation

Hen is a bird belonging to the class Aves and is oviparous, whereas the other three are mammals belonging to the class Mammalia and are viviparous.

Explanation

The sum of the positional values of the letters in the English alphabet for the other pairs is equal to 8. For the pair GF, the positional values of G (7) and F (6) sum up to 13, which does not follow this pattern and makes it the odd pair.

Explanation

The sum of the digits of the given number is 25 (6 + 9 + 4 + 6 = 25), whereas the sum of the digits of each of the other numbers is equal to 26.

Explanation

The number 4096 is an even number because its unit digit is 6, which makes it divisible by 2. In contrast, all other numbers in the given set are odd numbers because their unit digits are odd and not divisible by 2. This fundamental difference in mathematical parity distinguishes 4096 from the rest of the numbers in the group.

Explanation

The series represents a progressive hierarchical sequence of geographical divisions of increasing size. Jaipur is a city located within the state of Rajasthan. Rajasthan is a state located within the country of India. India is a country located within the continent of Asia. Each subsequent term represents a larger administrative or geographical entity that contains the preceding one.

Explanation

The series consists of groups of three consecutive letters in reverse alphabetical order.

Looking at the position values of the first letter of each group: Y is 25, T is 20, and N is 14. The difference between Y and T is 5, and between T and N is 6. Following this pattern of increasing differences (5, 6, 7), the next first letter must be 7 positions before N (14), which is G (7).

Applying this same logic to the other letters in each group: For the second letters: X (24) - 5 = S (19), S (19) - 6 = M (13), and M (13) - 7 = F (6). For the third letters: W (23) - 5 = R (18), R (18) - 6 = L (12), and L (12) - 7 = E (5).

Combining these results gives GFE.

Explanation

The positional values of the letters in the English alphabet follow a geometric progression where each term is doubled:

B = 2 D = 4 (2 × 2) H = 8 (4 × 2) P = 16 (8 × 2)

Following this pattern, the next position is 16 × 2 = 32. Since the English alphabet has 26 letters, we wrap around the alphabet by subtracting 26:

32 - 26 = 6

The 6th letter of the alphabet is F.

Explanation

The terms in the series represent the cubes of consecutive prime numbers.

8 = 2³ 27 = 3³ 125 = 5³ 343 = 7³

The prime numbers in sequence are 2, 3, 5, and 7. The next prime number in the sequence is 11. Taking its cube gives the next term:

11³ = 11 × 11 × 11 = 1331

Explanation

Conclusion II follows because since Sohan is a sportsman and all sportsmen are healthy, it logically follows that Sohan is healthy. Conclusion I does not follow because the statement that sportsmen are healthy does not imply that all healthy people are sportsmen.

Explanation

To determine the ranks of the five friends from highest (1st) to lowest (5th), we construct the ordering based on the given conditions.

First, Nitin scores the highest marks, placing him at the 1st position. Second, Ram scores the lowest marks, placing him at the 5th position. Third, Amit secures the 2nd position.

This leaves the 3rd and 4th positions to be filled by Priya and Juhi. Since Juhi scores lesser marks than Priya, Priya must rank higher than Juhi.

Therefore, the complete descending order of ranks is: Nitin Amit Priya Juhi Ram

This places Priya at the 3rd position.

Explanation

Comparing the words letter by letter reveals the alphabetical dictionary order. All four words begin with the letters Ga.

Looking at the third letter, Gabber has b, while Garbage, Garrulous, and Garbie have r. Since b comes before r, Gabber (iii) is the first word in the sequence.

Among the remaining words starting with Gar, we compare the fourth letter. Garbage and Garbie both have b, whereas Garrulous has r. Since b comes before r, Garrulous (ii) comes after both Garbage and Garbie, placing it at the end of the sequence.

To determine the order between Garbage and Garbie, we compare their fifth letters. Garbage has a, whereas Garbie has i. Since a comes before i, Garbage (i) appears before Garbie (iv).
