RRB NTPC CBT 1 2016 General Intelligence & Reasoning Questions with Solutions

Explanation

Comparing 'grapes are sweet' (592) and 'oranges are sour' (267), the common word is 'are' and the common digit is 2, so 2 represents 'are'.

Comparing 'I like oranges' (374) and 'oranges are sour' (267), the common word is 'oranges' and the common digit is 7, so 7 represents 'oranges'.

In the code 267 for 'oranges are sour', after assigning 2 to 'are' and 7 to 'oranges', the remaining digit 6 represents 'sour'.

Explanation

Each letter is replaced by the letter that immediately follows its opposite (reverse alphabet) letter. For SHIRT, the opposite letters are H, S, R, I, and G, and adding 1 to each position gives I, T, S, J, and H, which forms ITSJH.

Explanation

The given pair exhibits a raw material to finished product relationship, where yarn is the primary material used to weave or produce fabric. Similarly, metal is the raw material forged or processed to manufacture a sword.

Explanation

The numerical positions of the letters in each group increase by 4 for every corresponding position across the series:

First letters: B(2) + 4 = F(6), F(6) + 4 = J(10), J(10) + 4 = N(14), N(14) + 4 = R(18), R(18) + 4 = V(22) Second letters: C(3) + 4 = G(7), G(7) + 4 = K(11), K(11) + 4 = O(15), O(15) + 4 = S(19), S(19) + 4 = W(23) Third letters: A(1) + 4 = E(5), E(5) + 4 = I(9), I(9) + 4 = M(13), M(13) + 4 = Q(17), Q(17) + 4 = U(21)

Adding 4 to the positions of FGE (6, 7, 5) yields JKI (10, 11, 9).

Explanation

Each letter in the given code is transformed by shifting it forward by 13 positions in the alphabetical series (wrapping around from Z to A when necessary).

P (16) + 13 = 29 ≡ 3 (C) L (12) + 13 = 25 (Y) A (1) + 13 = 14 (N) T (20) + 13 = 33 ≡ 7 (G) E (5) + 13 = 18 (R)

Applying the same +13 shift to SHOCK:

S (19) + 13 = 32 ≡ 6 (F) H (8) + 13 = 21 (U) O (15) + 13 = 28 ≡ 2 (B) C (3) + 13 = 16 (P) K (11) + 13 = 24 (X)

Explanation

The maternal uncle of Salman's son is the brother of Salman's wife. Since Rahim's son is this maternal uncle, Rahim's son is Salman's wife's brother. This implies that Rahim is the father of Salman's wife, making Rahim the father-in-law of Salman.

Explanation

Statement 1 establishes that tea is green. Statement 2 specifies that more than half of the town likes tea, which means a majority (over 50%) of the town's population prefers green. Thus, conclusion I logically follows. Statement 3 states that people who like white (milk) do not like green (tea) and some people who like brown (coffee) do not like white (milk), but it provides no information establishing that any coffee drinker dislikes tea. Hence, conclusion II does not logically follow.

Explanation

The given pair represents an animal and its offspring. A young tiger is called a cub. Similarly, a young elephant is called a calf.

Explanation

A monopoly exists when a single seller or entity is the sole provider of a particular good or service in a given market. Since ST Bazaar is the only option available for the people of the town to buy groceries, it possesses a monopoly over the grocery market in that town.

Explanation

Arranging the parts in the sequence 69587 forms the grammatically complete and coherent sentence: "Gopu is a great writer and is also a famous mathematician." In this structure, "Gopu" (6) acts as the main subject, followed by the first predicate clause "is a great writer" (9), joined by the conjunction "and" (5), and concluded with the second parallel predicate clause "is also" (8) "a famous mathematician" (7).

Explanation

We look for occurrences of the triplet X 7 9 where X is any number other than 5.

Checking each 7 in the sequence: The first 7 forms 1 7 9, which is preceded by 1 (not 5) and followed by 9. The second 7 forms 9 7 5, which is followed by 5 instead of 9. The third 7 forms 5 7 9, which is preceded by 5. The fourth 7 forms 8 7 8, which is followed by 8 instead of 9. The fifth 7 forms 8 7 9, which is preceded by 8 (not 5) and followed by 9. The sixth 7 forms 5 7 9, which is preceded by 5.

The two valid occurrences meeting both conditions are 1 7 9 and 8 7 9.

Explanation

The given sequence follows the pattern of adding 1 to consecutive prime numbers:

2 + 1 = 3 3 + 1 = 4 5 + 1 = 6 7 + 1 = 8 11 + 1 = 12 13 + 1 = 14 17 + 1 = 18

The missing term is obtained by adding 1 to the prime number 13, which equals 14.

Explanation

When there are 5 people between Karan and Sunil, Sunil's position behind Karan is calculated as: Sunil's position = Karan's position + Number of people in between + 1 = 12 + 5 + 1 = 18th position

The five people between Karan (12th) and Sunil (18th) occupy the 13th, 14th, 15th, 16th, and 17th positions.

Explanation

Total number of balls = 2 + 3 + 4 + 6 = 15. Number of ways to select 2 balls out of 15 = C(15, 2) = (15 × 14) / 2 = 105.

For Conclusion I: Probability of selecting at least 1 black ball = 1 - C(12, 2) / C(15, 2) = 1 - 66 / 105 = 39 / 105 = 13 / 35. Probability of selecting exactly 1 black ball = (C(3, 1) × C(12, 1)) / 105 = 36 / 105 = 12 / 35. Neither value equals 1 / 5.

For Conclusion II: Probability of selecting at least 1 red ball = 1 - C(11, 2) / C(15, 2) = 1 - 55 / 105 = 50 / 105 = 10 / 21. Probability of selecting exactly 1 red ball = (C(4, 1) × C(11, 1)) / 105 = 44 / 105. Neither value equals 6 / 15.

Since two balls are drawn, the calculated probabilities do not match either conclusion.

Explanation

By assigning colors and professions to each person: Rosy likes Yellow and is a Student. Mary likes Purple and Andy likes Blue. Since the Inspector likes Blue, Andy is the Inspector. Lily likes Brown. The remaining color, Green, belongs to Daisy. Since the Librarian likes Green, Daisy is the Librarian. The remaining unassigned professions for Mary and Lily are Principal and Teacher. Since Mary is not a Teacher, she is the Principal, which assigns the Teacher profession to Lily.

Explanation

Mapping the friends, colors, and professions from the given conditions:

Rosy likes Yellow and is a Student. Andy likes Blue, and since the Inspector likes Blue, Andy is the Inspector. The remaining color for Daisy is Green, and since the Librarian likes Green, Daisy is the Librarian. Mary likes Purple and cannot be the Teacher, so Mary is the Principal. The remaining profession of Teacher belongs to Lily, who likes Brown.

Explanation

By mapping each person to their color and profession:

Rosy likes Yellow and is the Student. Lily likes Brown. Andy likes Blue, and since the Inspector likes Blue, Andy is the Inspector. Mary likes Purple. Daisy likes the remaining color, Green, making Daisy the Librarian.

The remaining professions are Teacher and Principal for Mary and Lily. Since Mary is not a Teacher, Mary must be the Principal.

Explanation

Rosy is explicitly stated as a Student who likes Yellow. By eliminating the given attributes, Andy is the Inspector, Daisy is the Librarian, Mary is the Principal, and Lily is the Teacher. Therefore, pairing Rosy with Teacher is incorrect.

Explanation

The relationship in the first pair, Deplete : Exhaust, is one of synonyms, as both words mean to use up or drain completely. Similarly, Replenish means to refill or bring back to a former condition, which is synonymous with Restore.

Explanation

From Statement 1, the height of X is 7 m, Y is 3.5 m (half of X), and Z is 21 m (3 times X).

For Conclusion I: Statement 2 states that both A and B are taller than P, who is taller than Z. Since there is no given relationship comparing the heights of A and B, it cannot be determined whether A or B is the tallest person.

For Conclusion II: The average height of X, Y, and Z is (7 + 3.5 + 21) ÷ 3 = 31.5 ÷ 3 = 10.5 m. Since 10.5 m is greater than 10 m, Conclusion II is incorrect.

Explanation

Mandatory and compulsory are exact synonyms, both referring to something that is required by law or rules. Similarly, hypothesis and supposition are exact synonyms, both denoting an assumption or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Explanation

By arranging the given conditions in order of decreasing height: From the first condition, Pole > Giraffe > Tree. From the second condition, Pole > Signal > Building > Giraffe.

Combining the two relations gives the complete order from tallest to shortest: Pole > Signal > Building > Giraffe > Tree

The height relation directly shows that Tree is shorter than every other entity.

Explanation

The series follows a pattern where each term increases by +2 positions in alphabetical order for both the first and second letters:

First letter: N (+2) → P (+2) → R (+2) → T (+2) → V (+2) → X (+2) → Z Second letter: A (+2) → C (+2) → E (+2) → G (+2) → I (+2) → K (+2) → M

Combining the missing fifth term gives VI.

Explanation

Unscrambling THEA forms the word HEAT, which represents a physical phenomenon rather than a part of the human body, whereas all the other jumbled letter sets form words representing human body parts.

Explanation

Sangeeta is the mother of Jagdish, and Harnish is Jagdish's maternal uncle, which means Harnish is Sangeeta's brother. Since Sangeeta is Sunil's sister, Harnish and Sunil are brothers. Karna is the son of Sunil, so his father's brother Harnish is his paternal uncle.

Explanation

Ink is the writing fluid contained inside a pen, representing a tool and its constituent material. In contrast, the remaining pairs follow a relationship where the first item is a writing instrument used directly upon the surface of the second item.

Explanation

Puducherry is a Union Territory composed of mainland coastal enclaves on the Indian peninsula, whereas the remaining entries are island groups or archipelagos.

Explanation

When arranging the given words in alphabetical order, Assert comes first as 's' precedes 'u' at the second letter position. Among the remaining words starting with 'Au', Auspicious and Austere come before Autumn because 's' precedes 't' at the third letter position. Between Auspicious and Austere, 'p' comes before 't' at the fourth letter position, placing Auspicious second and Austere third.

Explanation

The common feature shared by Olive Oil, Coconut Oil, Cod Liver Oil, and Sunflower Oil is that they are all classified as oils. While Olive, Coconut, and Sunflower oils are extracted from plant sources and Cod Liver oil is extracted from the liver of cod fish, they all belong to the broader category of lipids known as oils.

Explanation

The given sequence is an arithmetic progression where each term increases by a common difference of 14, representing consecutive multiples of 14:

14 × 1 = 14 14 × 2 = 28 14 × 3 = 42 14 × 4 = 56 14 × 5 = 70 14 × 6 = 84 14 × 7 = 98

The fifth term is calculated as 56 + 14 = 70.

Explanation

Each digit corresponds directly to a specific letter based on the given codes.

From READY (41095): 4 = R, 1 = E, 0 = A, 9 = D, 5 = Y From FRAILS (840327): 8 = F, 4 = R, 0 = A, 3 = I, 2 = L, 7 = S

Decoding 83145 gives 8 = F, 3 = I, 1 = E, 4 = R, 5 = Y, which spells FIERY. Decoding 419 gives 4 = R, 1 = E, 9 = D, which spells RED.

Combining both words produces FIERY RED.

Explanation

A monitor is an output device that receives processed data from a computer to display visual content to the user, distinguishing it as an output peripheral rather than an input peripheral.

Explanation

Each letter in the code is obtained by shifting the corresponding letter in the word forward by 11 positions in the alphabet (wrapping around Z to A).

For RATIONAL: R + 11 = C A + 11 = L T + 11 = E I + 11 = T O + 11 = Z N + 11 = Y A + 11 = L L + 11 = W

Applying the same +11 position shift to EXPERIENCE: E + 11 = P X + 11 = I P + 11 = A E + 11 = P R + 11 = C I + 11 = T E + 11 = P N + 11 = Y C + 11 = N E + 11 = P

This yields PIAPCTPYNP.

Explanation

Conclusion I introduces cars and financial affordability, which are completely outside the scope of the given statements. Conclusion II assumes a preference for orange over other bright colours based solely on scooter ownership, but owning a particular colour scooter does not logically establish a direct preference for that colour over all other bright options. Therefore, neither conclusion logically follows from the premises.

Explanation

Unscrambling IFER forms the word FIRE, which is a physical phenomenon, whereas all the other jumbled letter sets rearrange to form names of colors.

Explanation

Comparing 'are you sam' ('ri ai ki') and 'all hate you' ('vi li ri'), the common word is 'you' and the common code is 'ri', so 'you' = 'ri'.

Comparing 'all hate you' ('vi li ri') and 'all are fake' ('mi ai li'), the common word is 'all' and the common code is 'li', so 'all' = 'li'.

In 'all hate you' = 'vi li ri', since 'you' corresponds to 'ri' and 'all' corresponds to 'li', the remaining word 'hate' must correspond to 'vi'.

Explanation

M's grandfather's only son is M's father. The daughter of M's father is K, which means K is M's sister. Since M and K share the same parents, M is the sister (or sibling) of K.

Explanation

The passage explicitly states that one of the main reasons for traffic crawling during peak hours is the "increasing number of private vehicles," which directly confirms that the number of private vehicles has gone up.

Explanation

Screen is an Indian weekly film magazine published by The Indian Express Group, focusing on Bollywood and entertainment journalism. It represents print media, making it distinct from television broadcasting networks.

Explanation

The pattern in the series is obtained by multiplying each term by 2 and subtracting 1:

12 × 2 - 1 = 23 23 × 2 - 1 = 45 45 × 2 - 1 = 89 89 × 2 - 1 = 177

Alternatively, the difference between consecutive terms doubles at each step: 11, 22, 44, and 88. Adding 88 to 89 gives 177.

Explanation

The code for each word is calculated by summing the alphabetical position values of its individual letters.

F = 6 THE = 20 + 8 + 5 = 33

Applying the same rule to WOMAN: W = 23, O = 15, M = 13, A = 1, N = 14 23 + 15 + 13 + 1 + 14 = 66

Explanation

Substituting the operators as per the given instructions: '+' becomes '-', '-' becomes '÷', 'x' becomes '+', and '÷' becomes '×'.

Original expression: 22 + 36 - 12 x 6 ÷ 4

New expression: 22 - 36 ÷ 12 + 6 × 4

Applying the BODMAS rule: Division: 36 ÷ 12 = 3 Multiplication: 6 × 4 = 24

22 - 3 + 24 = 19 + 24 = 43

Explanation

Total number of kids = 50.

Kids who like volleyball include those who like only volleyball (5) and those who like both volleyball and football (10), giving a total of 5 + 10 = 15 kids.

Kids who do not like volleyball = Total kids - Kids who like volleyball = 50 - 15 = 35.

Alternatively, kids who do not like volleyball consist of those who like only basketball and those who like only football: 10 + 25 = 35.

Explanation

Number of kids who like football = Kids who like only football + Kids who like both volleyball and football = 25 + 10 = 35.

Number of kids who like only basketball = 10.

Required ratio = 35 / 10 = 7 / 2.

Explanation

While snow, blood, and grass are tangible physical substances with specific natural colors derived from their physical composition, the sky is an atmospheric expanse rather than a solid or liquid object. Furthermore, the blue appearance of the sky is an optical phenomenon caused by Rayleigh scattering of sunlight in the Earth's atmosphere, which changes color depending on the time of day and weather, unlike the intrinsic visual properties of physical matter.

Explanation

Designed by Sir Edwin Lutyens and Herbert Baker, Rashtrapati Bhavan is the official residence of the President of India located at Raisina Hill in New Delhi. It is not designated as a UNESCO World Heritage Site.

Explanation

Crude oil is the primary raw material used to refine petrol. A decline in international crude oil prices reduces the procurement and import costs for domestic oil refineries, which directly leads to a reduction in the retail price of petrol in the domestic market.

Explanation

Silicon Valley is a global center for technology and innovation located in Northern California, United States, making it a region situated outside the Indian subcontinent.

Explanation

The Milky Way is a vast barred spiral galaxy that contains our Solar System alongside hundreds of billions of other stars and celestial objects. In contrast, a constellation is a specific region of the night sky defined by a recognized pattern or group of stars.

Explanation

Sum of the students in the specified categories: Only Algebra = 12 Only Geometry = 13 Only Trigonometry = 10 Only Physics = 8 Both Algebra and Trigonometry = 5 Both Physics and Geometry = 5 Total accounted for = 12 + 13 + 10 + 8 + 5 + 5 = 53

Remaining students who like both Algebra and Physics = 60 − 53 = 7

Students who like Physics but not Geometry include those who like only Physics and those who like both Algebra and Physics: Total = 8 + 7 = 15
