RRB NTPC Graduate CBT 1 2024 PYQs

Concept: Look for the pattern Number – Symbol – Symbol and count the middle symbol.

1. 3 € & → € preceded by 3, followed by & ✓
2. 1 $ € → $ preceded by 1, followed by € ✓
3. 1 € 4 → followed by a number ✗; 4 © at the end → nothing follows ✗
4. Count = 2

Trick: List every number, then check the next two places: symbol + symbol.

Answer: (D) $2$

Concept: Track the position on a grid (East +x, North +y); a right turn while facing South points West.

1. A(0, 0) → 11 km South → (0, −11)
2. Right (West) 9 km → (−9, −11); right (North) 12 km → (−9, 1)
3. Right (East) 12 km → (3, 1); right (South) 1 km → P(3, 0)
4. P is 3 km East of A, so he must drive 3 km to the West.

Trick: Net East = 12 − 9 = 3 km; net North = 12 − 11 − 1 = 0 → move 3 km West.

Answer: (A) 3 km to the west

Concept: A letter common to two words takes the digit common to both codes.

1. GIVE → 6482 and VOLT → 3671
2. Common letter: V; common digit: 6
3. So V = 6.

Trick: Match common letters with common digits – order inside the code does not matter.

Answer: (B) $6$

Concept: Find the differences between consecutive terms.

1. $892-2=890$, $890-4=886$, $886-6=880$, $880-8=872$
2. Differences grow by 2: next is $-10$
3. $872-10=862$

Trick: Subtracting consecutive even numbers – the next difference is 10.

Answer: (A) $862$

Concept: Write letter positions and compare the two clusters of each pair.

1. LQ–SP: $L(12)\stackrel{+5}{\to }Q(17)$; $L\stackrel{+7}{\to }S$, $Q\stackrel{-1}{\to }P$
2. UZ–BY: $U\stackrel{+5}{\to }Z$; $U\stackrel{+7}{\to }B$, $Z\stackrel{-1}{\to }Y$; EJ–LI: $E\stackrel{+5}{\to }J$; $E\stackrel{+7}{\to }L$, $J\stackrel{-1}{\to }I$
3. JO–QM: $J\stackrel{+5}{\to }O$, $J\stackrel{+7}{\to }Q$, but $O\stackrel{-2}{\to }M$ ✗

Trick: Check the last letters: second letter $-1$ in three pairs; only JO–QM breaks it.

Answer: (A) JO – QM

Concept: Place the fixed clues first, then fill the rest.

1. A odd, not 3 → 1 or 5; $C+A=4$ → A = 1, C = 3
2. $D+E=10$ → (4, 6) or (6, 4); B just above D → D = 4, B = 5, so E = 6
3. F gets the only free floor, 2; check: between E(6) and F(2) are 3 people ✓
4. Below F: only A → 1 person

Trick: Sum clues with small totals (A + C = 4) fix positions fastest.

Answer: (B) $1$

Concept: A word common to two sentences takes the code common to both.

1. smooth long drive → zi ma tu
2. challenging mountain drive → fo se zi
3. Common word "drive" ↔ common code "zi".

Trick: Common word ↔ common code; position in the sentence is irrelevant.

Answer: (C) zi

Concept: For people facing the centre, left = clockwise and right = anticlockwise.

1. Fix I; counting to I's left, H is the 4th seat (3 between).
2. Number seats clockwise from I (I = 0, H = 4). B sits between G and H. If B = 3, G = 2, then A = 5 and C = 4 = H ✗. So B = 5 and G = 6.
3. A is 4th to G's right (seat 2), C is just right of A (seat 1), and D takes the last seat: clockwise I, C, A, D, H, B, G.
4. Two seats to D's left (clockwise): H, then B.

Trick: Draw the circle and mark arrows for "left" before placing anyone.

Answer: (B) B

Concept: Find the operations from the given sets.

1. $6\stackrel{\times 2}{\to }12\stackrel{+3}{\to }15\stackrel{\times 2}{\to }30$; $4\stackrel{\times 2}{\to }8\stackrel{+3}{\to }11\stackrel{\times 2}{\to }22$
2. (C): $11\stackrel{\times 2}{\to }22\stackrel{+3}{\to }25\stackrel{\times 2}{\to }50$ ✓
3. (D) fails: $19\times 2=38\ne 36$; (A), (B) fail at the first step.

Trick: Pattern $\times 2,+3,\times 2$ → the last term must be even and twice the third.

Answer: (C) 11 - 22 - 25 - 50

Concept: Number the positions 1 (bottom) to 7 (top) and place the definite boxes first.

1. Two below C → C = 3; one above A → A = 6
2. One box between A and E → E = 4
3. B just above F: the only adjacent free pair is 1–2 → F = 1, B = 2
4. D below G → D = 5, G = 7. Order (bottom→top): F, B, C, E, D, A, G
5. Boxes above B = 7 − 2 = 5

Trick: Boxes above position p = 7 − p.

Answer: (B) $5$

Concept: Check the differences between consecutive terms.

1. $982-980=2$, $980-976=4$, $976-970=6$, $970-962=8$.
2. Differences are even numbers increasing by 2, so the next difference is $10$.
3. $962-10=952$.

Trick: Subtract consecutive even numbers: $-2,-4,-6,-8,-10$.

Answer: (A) 952

Concept: Apply the rule digit by digit.

1. 596432: odd digits $5,9,3$ become $2,6,0$; even digits $6,4,2$ become $8,6,4$.
2. New number: 2 6 8 6 0 4.
3. Greatest digit $=8$, smallest digit $=0$, sum $=8+0=8$.

Trick: Only the extreme digits matter: largest even digit $6\to 8$ and odd digit $3\to 0$.

Answer: (A) 8

Concept: Replace the letters by signs, then use BODMAS.

1. Expression: $43-15+7\times 9-(28÷2)$.
2. Bracket: $28÷2=14$; multiplication: $7\times 9=63$.
3. $43-15+63-14=77$.

Trick: Write the sign-converted expression first, then solve bracket → ×/÷ → +/−.

Answer: (D) 77

Concept: Fix definite positions first (number the seats 1–7 from left).

1. No one to the left of J → J at 1; four people between J and K → K at 6.
2. Three people to the right of O → O at 4.
3. I immediately left of L: only free adjacent pair is 2–3 → I at 2, L at 3.
4. P and Q take 5 and 7; P is not next to O → P at 7, Q at 5.

Trick: 'No one to the left' = extreme left end; use the count clues next.

Answer: (A) P

Concept: Track the position on a coordinate grid, taking A as $(0,0)$.

1. 6 km North → $(0,6)$; right turn = East 7 km → $(7,6)$.
2. Right = South 12 km → $(7,-6)$; right = West 8 km → $(-1,-6)$.
3. Right = North 6 km → P $=(-1,0)$.
4. P is 1 km west of A, so he must drive 1 km towards the East.

Trick: Net East–West $=7-8=-1$; net North–South $=6-12+6=0$.

Answer: (D) 1 km to the east

Concept: Match common letters with common digits.

1. FARE → 8, 4, 3, 2 and FEAT → 3, 2, 8, 7.
2. Common letters F, A, E ↔ common digits 8, 3, 2.
3. Letter only in FARE is R; digit only in its code is 4. So R = 4 (and T = 7).

Trick: Uncommon letter ↔ uncommon digit in the same word.

Answer: (D) 4

Concept: Look for the pattern number–number–number.

1. 2 2 7: the second 2 is preceded by 2 and followed by 7 ✔.
2. 9 3 6: 3 is preceded by 9 and followed by 6 ✔.
3. Others fail (e.g. 8 6 *: 6 is followed by a symbol; 3 6 &: 6 is followed by a symbol).

Trick: Find runs of 3 or more consecutive numbers; each run of length $k$ gives $k-2$ answers.

Answer: (C) 2

Concept: Identify the highest and lowest numbers, then pick the required digits.

1. Highest number $=503$ → second digit $=0$.
2. Lowest number $=144$ → first digit $=1$.
3. $0+1=1$.

Trick: Compare the hundreds digits first: 5 is highest, 1 lowest (144 is less than 158).

Answer: (D) 1

Concept: Check each condition against AJSPT, then code letter by letter.

1. Condition 1: 1st letter A is a vowel and 3rd letter S is a consonant → applies; both A and S get the code of S, i.e. @.
2. Condition 2: last letter T is not a vowel → not applicable. Condition 3: 2nd letter J is not a vowel → not applicable.
3. Codes: A → @, J → $, S → @, P → %, T → *.

Trick: Test the conditions first; only then use the table.

Answer: (D) @ $ @ % *

Concept: Place the fixed persons first, then use the remaining clues.

1. S on floor 5; O above S → O on floor 6.
2. Only T lives below N → T on floor 1, N on floor 2.
3. U on an even floor; only 4 is left even → U on floor 4, so M on floor 3.
4. Below M: T and N → two people.

Trick: 'Only X lives below Y' fixes X at the bottom and Y just above it.

Answer: (C) Two
