RRB NTPC CBT 1 2021 General Intelligence & Reasoning Questions with Solutions

Explanation

Odia is the official language spoken in the state of Odisha. Following the same relationship between a state and its principal language, Malayalam is the official language spoken in the state of Kerala.

Explanation

The given series follows two alternating patterns for the positions and values of letters and numbers:

The position alternates between Letter/Number and Number/Letter. Since the fifth term is Letter/Number (O/13), the sixth term must be in the Number/Letter format.

The letter positions in the alphabet increase by +3 each time: C (3), F (6), I (9), L (12), O (15), giving R (18) for the next term.

The numerical values decrease by -4 each time: 29, 25, 21, 17, 13, giving 9 for the next term.

Placing 9 in the numerator and R in the denominator yields 9/R.

Explanation

The pattern follows a column-wise relation where Row 3 = (Row 1 + Row 2) × 2.

For the second column: (5 + 1) × 2 = 12 For the third column: (4 + 5) × 2 = 18

Applying the same logic to the first column: (4 + ?) × 2 = 32 4 + ? = 16 ? = 12

Explanation

Assumption I is implicit because the signboard explicitly links keeping the door closed to maintaining a germ-free room, implying that leaving the door open would allow germs to enter. Assumption II is implicit because any notice or signboard is put up under the underlying premise that people will pay attention to it and comply with the instruction.

Explanation

The construct "Though I do not like X, I enjoyed Y" logically assumes that Y is a specific instance or category of X, acting as an exception to the speaker's general distaste for X. For the statement to make logical sense, the speaker must assume that 'PK' is an Indian film, making Assumption I implicit.

Explanation

The series follows a pattern where each letter decreases by 3 positions in alphabetical order:

First letters: X (24) - 3 = U (21), U (21) - 3 = R (18), R (18) - 3 = O (15), O (15) - 3 = L (12), L (12) - 3 = I (9).

Second letters: Q (17) - 3 = N (14), N (14) - 3 = K (11), K (11) - 3 = H (8), H (8) - 3 = E (5), E (5) - 3 = B (2).

Combining the next first and second letters gives IB.

Explanation

The given series consists of three distinct patterns for the first letter, the middle number, and the last letter:

First letter: Decreases by 3 in alphabetical position each step. U(21) - 3 = R(18), R(18) - 3 = O(15), O(15) - 3 = L(12), L(12) - 3 = I(9), and I(9) - 3 = F(6).

Middle number: Increases by adding doubling differences (+5, +10, +20, +40, +80). 9 + 5 = 14, 14 + 10 = 24, 24 + 20 = 44, 44 + 40 = 84, and 84 + 80 = 164.

Third letter: Decreases by 3 in alphabetical position each step. Y(25) - 3 = V(22), V(22) - 3 = S(19), S(19) - 3 = P(16), P(16) - 3 = M(13), and M(13) - 3 = J(10).

Combining these results gives the missing term I84M.

Explanation

The pattern shifts each letter forward by its positional index in the word (+1, +2, +3, +4, +5, +6, ...).

Applying this shift pattern to FIERCE gives: F + 1 = G I + 2 = K E + 3 = H R + 4 = V C + 5 = H E + 6 = K

This produces the coded word GKHVHK.

Explanation

The code is obtained by multiplying the sum of the alphabetical positional values of all the letters in the word by 3.

For FLOCK: F (6) + L (12) + O (15) + C (3) + K (11) = 47 47 × 3 = 141

For CREW: C (3) + R (18) + E (5) + W (23) = 49 49 × 3 = 147

Explanation

The given series follows three independent patterns:

First letter: Increases by +2 in alphabetical order (H = 8, J = 10, L = 12, N = 14, P = 16, R = 18).

Middle number: The difference between consecutive numbers increases by consecutive squares (1², 2², 3², 4², 5²): 5 + 1 = 6, 6 + 4 = 10, 10 + 9 = 19, 19 + 16 = 35, 35 + 25 = 60.

Third letter: Decreases by -2 in alphabetical order (S = 19, Q = 17, O = 15, M = 13, K = 11, I = 9).

Combining these three parts yields R60I.

Explanation

A poet creates a poem as their end product or creation. In the same way, a cook prepares or creates food as their primary output.

Explanation

Y's grandfather has only one child, who is a son, which means this only son is Y's father. Since X is the only daughter of Y's father, X must be the sister of Y.

Explanation

The pattern in the series is based on subtracting consecutive numbers that increase by 1 at each step:

50 - 0.5 = 49.5 49.5 - 1.5 = 48 48 - 2.5 = 45.5 45.5 - 3.5 = 42 42 - 4.5 = 37.5

Subtracting 1.5 from 49.5 yields 48.

Explanation

Statement 1 establishes that employees belong to the category of people who earn well, but it does not state that only employees earn well. Statement 2 indicates that Rajan earns well, placing him in the group of well-paid individuals. However, earning well does not guarantee that Rajan is an employee, nor does it establish that he is self-employed. Since neither conclusion can be definitively deduced from the given statements, neither conclusion follows.

Explanation

Orange, Peach, Olive, and Carmine are all names of distinct colours or colour shades. Orange represents a hue between red and yellow, Peach is a light pinkish-orange shade, Olive is a dark yellowish-green tone, and Carmine is a vivid, deep red colour.

Explanation

The series consists of consecutive pairs of letters from the English alphabet, alternating between reversed and forward order:

GH is written in reversed order as HG. IJ is written in forward order as IJ. KL is written in reversed order as LK. MN is written in forward order as MN.

Following this alternating pattern, the next consecutive pair OP must be written in reversed order, giving PO.

Explanation

The shop owner's criteria specify that dry fruits kept in the shop must be priced at more than Rs. 125 per 100 grams. Dry fruit Z is priced at Rs. 100 per 100 grams, which is less than the minimum required threshold of Rs. 125 per 100 grams, violating the inventory rules.

Explanation

Each letter in the word is shifted forward by 13 positions in alphabetical order:

D (4) + 13 = Q (17) E (5) + 13 = R (18) L (12) + 13 = Y (25) H (8) + 13 = U (21) I (9) + 13 = V (22)

Applying the same +13 position shift to BOMBAY:

B (2) + 13 = O (15) O (15) + 13 = B (2) M (13) + 13 = Z (26) B (2) + 13 = O (15) A (1) + 13 = N (14) Y (25) + 13 = L (12)

This yields OBZONL.

Explanation

This question follows a direct letter-to-digit substitution scheme where each letter is assigned a specific digit from the given words: G = 3, O = 8, I = 2, N = 5, C = 4, A = 0, S = 9, U = 1, and L = 6.

Applying these digit values to each letter in LOGICAL gives L = 6, O = 8, G = 3, I = 2, C = 4, A = 0, and L = 6. Combining these values in order yields 6832406.

Explanation

Seeta's son's father is Seeta's husband. The father of Seeta's husband is her son's paternal grandfather. Since Ram's only brother is the father of Seeta's husband, Ram's brother is the grandfather of Seeta's son.

Explanation

Rearranging EPPI gives PIPE, which represents a physical object, whereas the other sets of letters rearrange to form number words.

Explanation

The pattern follows an alternating sequence of adding 1 and subtracting 1 to the position of each letter in the alphabet (+1, -1, +1, -1, +1, -1):

G (+1) = H U (-1) = T I (+1) = J T (-1) = S A (+1) = B R (-1) = Q

Applying the same rule to VIOLIN: V (+1) = W I (-1) = H O (+1) = P L (-1) = K I (+1) = J N (-1) = M

Explanation

Positions of jars from left to right (1 to 5) are determined step-by-step:

Garlic is at position 2.

Since there is one jar between mango and garlic, mango must be at position 4.

Gooseberry cannot be at either extreme (positions 1 or 5), so it must be at position 3.

Tomato is to the left of lime, placing tomato at position 1 and lime at position 5.

The final arrangement from left to right is: 1. Tomato, 2. Garlic, 3. Gooseberry, 4. Mango, 5. Lime.

Between Tomato (position 1) and Mango (position 4), there are exactly two jars (Garlic at position 2 and Gooseberry at position 3).

Explanation

From the given clues, the jars from left to right (positions 1 to 5) can be uniquely determined:

The second jar contains Garlic (Position 2 = Garlic). Since there is one jar between Mango and Garlic, Mango must be placed in the fourth jar (Position 4 = Mango). Gooseberry cannot be at either extreme (positions 1 or 5), so it must be in the third jar (Position 3 = Gooseberry). Tomato is placed to the left of Lime, which places Tomato in the first jar and Lime in the fifth jar (Position 1 = Tomato, Position 5 = Lime).

Thus, Lime is in the fifth jar from the left.

Explanation

Numbering the jar positions 1 to 5 from left to right:

Garlic is placed in position 2 as given. Since there is one jar between mango and garlic, mango must be in position 4. This leaves positions 1, 3, and 5 for gooseberry, tomato, and lime.

Since gooseberry cannot be at either extreme end (positions 1 or 5), it must be placed in position 3, which is the middle jar. Tomato is placed in position 1 and lime in position 5 to satisfy tomato being to the left of lime.

Explanation

Interchanging the signs - and ÷ transforms the equation into:

2 - 16 ÷ 2 + 6 × 1 = 0

Applying BODMAS order of operations: First, perform division: 16 ÷ 2 = 8 Second, perform multiplication: 6 × 1 = 6

The expression simplifies to: 2 - 8 + 6 = -6 + 6 = 0

This makes the left-hand side equal to the right-hand side (0 = 0).

Explanation

Anand's father's mother-in-law is Anand's maternal grandmother. The eldest son of Anand's maternal grandmother is Anand's mother's brother. Since Anand's mother and this man share the same mother, she is his sister.

Explanation

Leaves contain a green pigment called chlorophyll within their chloroplasts. Chlorophyll absorbs red and blue light wavelengths from sunlight during photosynthesis and reflects green light back to our eyes, causing leaves to appear green in colour.

Explanation

An increase in the price of pulses indicates that pulses have become more expensive, but it does not imply that people are completely unable to purchase them. Higher prices may affect affordability for some, but it does not eliminate purchasing capacity entirely. Furthermore, a price rise can be driven by various economic factors such as inflation, increased demand, higher taxes, or transportation costs, and does not automatically mean that pulses have become a rare commodity. Therefore, neither conclusion logically follows from the given statement.

Explanation

The given words "Truthful" and "Honest" are synonyms, as both describe a person or statement that is truthful, sincere, and free of deceit. Similarly, "Notwithstanding" and "Nevertheless" are synonyms, both serving as conjunctions or adverbs that mean "in spite of that" or "despite". Thus, both pairs share a synonymic relationship.

Explanation

Light is an external physical stimulus rather than a human body organ. The sensory organ responsible for vision is the eye, making this pair fundamentally different because light is an external medium required for sight rather than a body organ that performs the function.

Explanation

The given code follows direct letter-to-symbol substitution based on the provided words:

From INSECT = @ !#, the mappings are I = @, N = , S = , E = !, C = #, T =. From OR = %?, the mappings are O = %, R = ?.

Substituting these symbol mappings for the word CISTERN gives: C = # I = @ S = * T = E = ! R = ? N =

Combining these in order produces the coded string #@*!? .

Explanation

Since A, B, and C are brothers with a paternal aunt D, D is the sister of their father. D's brother E is married to F, and F's brother G has an only nephew, H. This means the only son of E and F is H. Consequently, A, B, and C cannot be the children of E, as that would give G multiple nephews. Since E is a brother of paternal aunt D but not the father of A, B, and C, E is another brother of A's father, making E the paternal uncle of A.

Explanation

Lungs is female because Stomach is her husband. Since Kidney is the son of Lungs, Pancreas being the maternal uncle of Kidney means Pancreas is the brother of Kidney's mother. Therefore, Pancreas is the brother of Lungs.

Explanation

When a governing authority issues an instruction, it operates under the implicit expectation that the target entities will comply. Assuming that private colleges will not follow the directive directly contradicts the premise behind issuing government instructions. Additionally, government measures to freeze fee hikes are intended to protect parents from financial strain, operating under the assumption that fee increases are an unwanted burden, not that parents are eager to pay higher fees. Both assumptions are invalid.

Explanation

In each row, the third number is obtained by subtracting the first number from the second number:

Row 1: 39 - 25 = 14 Row 3: 72 - 63 = 9

Applying the same logic to Row 2: ? = 51 - 18 = 33

Explanation

A motorcycle is a two-wheeled motor vehicle, whereas the rest are four-wheeled enclosed vehicles.

Explanation

The common pattern among the letter-clusters involves positional shifts of -1, +4, and -2 between consecutive letters in alphabetical order. In MLPO, the shifts are -1, +4, and -1 (M = 13, L = 12, P = 16, O = 15), as 16 - 1 = 15 instead of subtracting 2.

Explanation

The transformation logic applies alternating addition and subtraction of consecutive integers (+1, -2, +3, -4, +5, -6, +7, ...) to the alphabetical position of each letter.

Applying this pattern to ENQUIRY: E (+1) = F N (-2) = L Q (+3) = T U (-4) = Q I (+5) = N R (-6) = L Y (+7) = F

Applying the exact same rule to RESERVATION: R (+1) = S E (-2) = C S (+3) = V E (-4) = A R (+5) = W V (-6) = P A (+7) = H T (-8) = L I (+9) = R O (-10) = E N (+11) = Y

This yields SCVAWPHLREY, which corresponds to Code 2.

Explanation

Shiva is listed among the intelligent persons (Kapil, Shiva, Hari). Shiva does not appear in the group of hard working persons (Kapil, Ravi, Jitin) or in the group of honest persons (Ravi, Hari, Jitin). Thus, Shiva meets all the criteria of being intelligent while being neither honest nor hard working.

Explanation

In this pattern, each letter is paired with its numerical positional rank in the standard English alphabet, where A = 1, B = 2, ..., Z = 26. The letter A corresponds to the positional rank 1, so pairing it with 12 violates this rule and makes it the odd cluster.

Explanation

Substituting the mathematical operators as per the given instructions: Subtraction (-) becomes Multiplication (×) Multiplication (×) becomes Addition (+) Division (÷) becomes Subtraction (-) Addition (+) becomes Division (÷)

after applying the operator replacements, the expression transforms into: 13 × 2 + 4 - 9 ÷ 3

Applying the BODMAS order of operations: Division: 9 ÷ 3 = 3 Multiplication: 13 × 2 = 26 Addition and Subtraction: 26 + 4 - 3 = 27

Explanation

Combining the given relations regarding earnings step-by-step:

From "R earns more than Q but less than U", we get U > R > Q. From "P does not earn as much as Q but earns more than S", we get Q > P > S. From "P earns more than T", we know T earns less than P.

Merging these inequalities yields the complete order U > R > Q > P > (S, T), placing U strictly above all other five friends.

Explanation

The alphabetical positions of N and U are 14 and 21 respectively, giving a distance of 21 - 14 = 7 steps. Adding this same distance to H (8th letter) yields 8 + 7 = 15, which corresponds to the letter O.

Explanation

The pattern used to convert STATION into RUZUHPM alternates between subtracting 1 and adding 1 to the alphabetical positions of consecutive letters:

S (-1) = R T (+1) = U A (-1) = Z T (+1) = U I (-1) = H O (+1) = P N (-1) = M

Applying this same alternating rule (-1, +1, -1, +1, ...) to the word LOCOMOTIVE gives:

L (-1) = K O (+1) = P C (-1) = B O (+1) = P M (-1) = L O (+1) = P T (-1) = S I (+1) = J V (-1) = U E (+1) = F

This generates the sequence KPBPLPSJUF, which matches Code 3.

Explanation

Each letter in the word is shifted back by one position (-1) in the alphabetical sequence:

B - 1 = A R - 1 = Q A - 1 = Z I - 1 = H N - 1 = M

Applying the same pattern to BEAN:

B - 1 = A E - 1 = D A - 1 = Z N - 1 = M

Explanation

The series follows the pattern of subtracting 1 from the cubes of consecutive odd numbers:

1³ - 1 = 1 - 1 = 0 3³ - 1 = 27 - 1 = 26 5³ - 1 = 125 - 1 = 124 7³ - 1 = 343 - 1 = 342

Explanation

Total number of children in a row = (Position from left) + (Position from right) - 1.

Substituting the given values: Total = 16 + 16 - 1 = 31.

Explanation

When moving to the right from a position measured from the right end, subtract the number of steps from the initial rank.

Position from the right end = 18 - 7 = 11th letter from the right end.

To find its position from the left end, subtract from 27 (since total letters = 26): Position from the left end = 27 - 11 = 16th letter.

The 16th letter of the English alphabet is P.

Explanation

When a statutory or public safety warning is printed on a package, it is inherently assumed that consumers read the text printed on the packet and take note of the message conveyed. If people did not read printed matter or pay attention to warnings, printing such messages would serve no purpose. Therefore, both assumptions I and II are implicit in printing the warning on cigarette packets.
