RRB NTPC Graduate CBT 1 2024 PYQs

Concept: Track the coordinates of each leg starting from Y at (0, 0).

1. 12 km north → (0, 12); left = west 2 km → (−2, 12).
2. Right = north 1 km → (−2, 13); left = west 14 km → (−16, 13).
3. Left = south 13 km → X (−16, 0): X is on the same line as Y, 16 km to its west.
4. So he must drive 16 km towards the east.

Trick: North total $12+1=13$ cancels south $13$; only the west moves $2+14=16$ remain.

Answer: (D) 16 km towards the east

Concept: Fix the definite clues first, then place the pairs of consecutive days.

1. V = Wednesday; only one exam after T → T = Saturday.
2. Free days: Mon, Tue, Thu, Fri, Sun. R–P must be consecutive with P not on Tuesday → R = Thu, P = Fri.
3. S–U consecutive → S = Mon, U = Tue; Q = Sun.
4. Between P (Fri) and Q (Sun): only T → one person.

Trick: Place "block" clues (two consecutive days) in the only gaps big enough for them.

Answer: (C) One

Concept: Change each digit as instructed and then read the required positions.

1. 1845637 → 1+1, 8−2, 4−2, 5+1, 6−2, 3+1, 7+1 = 2 6 2 6 4 4 8.
2. Second from left = 6; second from right = 4.
3. Sum $=6+4=10$.

Trick: Only the two required digits matter: 8 → 6 and 3 → 4.

Answer: (B) 10

Concept: Find the shift for each letter of the example pair.

1. U→S, Q→O, N→L, V→T: each −2.
2. Check: XTQY → VROW ✔.
3. R→P, N→L, K→I, S→Q → PLIQ.

Trick: Uniform −2 shift: subtract 2 from every letter.

Answer: (A) PLIQ

Concept: Check the differences between consecutive terms.

1. $277-254=23$, $254-221=33$ → differences increase by $10$.
2. Next difference $43$: $221-43=178$.
3. Check: $178-53=125$, $125-63=62$ ✔.

Trick: Differences $23,33,43,53,63$ – an arithmetic pattern.

Answer: (C) 178

Concept: A letter common to both words must have the digit common to both codes.

1. CURE → 3527; EATS → 1246.
2. Common letter: E. Common digit: 2.
3. So E = 2.

Trick: Common letter ↔ common digit.

Answer: (B) 2

Concept: For people facing the centre, moving to the left means moving clockwise and to the right means anticlockwise.

1. Place B; D is to B’s immediate right.
2. Going left from D, three people are skipped, so E is the 4th seat from D; C is placed with three people between B and C (the other side is taken by E).
3. F is immediately right of A: the only free adjacent pair gives F next to B and A next to F; G takes the last seat.
4. Order (clockwise): B, F, A, E, C, G, D. Left of A: E, C, G, D then B → four people.

Trick: Draw the circle first and fix one person; for "facing centre", left = clockwise.

Answer: (D) Four

Concept: Use the "only" clues to fix the extreme floors.

1. Only H lives below G → H = 1, G = 2.
2. Only I lives above S → I = 6, S = 5.
3. T immediately below S → T = 4; remaining N = 3.

Trick: "Only X below Y" puts Y on floor 2 and X on floor 1.

Answer: (B) N

Concept: Find the position differences between consecutive letters (counting backward, wrapping Z→A).

1. QJGB: Q→J −7, J→G −3, G→B −5.
2. HAXS: H→A −7, A→X −3 (wrap), X→S −5. BURM: B→U −7 (wrap), U→R −3, R→M −5.
3. TMJF: T→M −7, M→J −3, J→F −4 ✘ → odd one.

Trick: Treat the alphabet as a circle; check every gap, the odd one breaks only one gap.

Answer: (D) TMJF

Concept: Compare letter positions across the pair (with wrap-around after Z).

1. UP – CW: U→C +8, P→W +7. JE – RL: J→R +8, E→L +7.
2. BW – JD: B→J +8, W→D +7 (wrap).
3. DY – LE: D→L +8 but Y→E +6 ✘ → odd one.

Trick: Check first-letter and second-letter shifts separately; the odd pair breaks one of them.

Answer: (D) DY – LE

Concept: Track the position as coordinates, taking Y as origin, East as $+x$ and North as $+y$.

1. East 47: $(47,0)$; right turn → South 23: $(47,-23)$.
2. Right → West 26: $(21,-23)$; right → North 52: $(21,29)$.
3. Left → West 21: $(0,29)$; left → South 11: $Z=(0,18)$.
4. Z is 18 km directly north of Y, so he must drive 18 km towards the south.

Trick: Net E–W: $47-26-21=0$; net N–S: $-23+52-11=18$ north. Return trip is the opposite direction.

Answer: (B) 18 km towards the south

Concept: Facing the centre, “left” means moving clockwise and “right” anticlockwise.

1. Fix F; B is third to the left of F.
2. Only F sits between A and C, so A and C are on either side of F; with C second to the left of D, only the order C, F, A (clockwise) with D two places right of C works.
3. G is not next to B, so E sits beside B and A: order clockwise A, E, B, D, G, C, F.
4. From the left of D (clockwise): D → G, C, F → A, i.e. 3 people between.

Trick: Place the person named most often (F) first, then fix the “only one between” clue.

Answer: (D) Three

Concept: Find the letter shift from the right pair and apply it to the left pair.

1. Option B: F+5 = K, N+5 = S, W+5 = B (after Z, back to A), so FNW → KSB.
2. Apply +5 to NVE: N+5 = S, V+5 = A, E+5 = J → SAJ.
3. Both blanks are satisfied only by # = FNW, % = SAJ.

Trick: Check each option’s shift on the first pair; the matching one must give the same shift on the second pair.

Answer: (B) # = FNW, % = SAJ

Concept: Check every symbol: the element just before and just after it must both be numbers.

1. 7 € 2 ✓, 3 © 8 ✓, 8 © 4 ✓, 4 € 9 ✓, 3 € 5 ✓, 7 $ 1 ✓.
2. #, % and * fail (they are next to other symbols).
3. Total = 6.

Trick: Skip blocks of consecutive symbols — none of them can qualify.

Answer: (C) 6

Concept: Decode each symbol step by step and draw the family tree.

1. P + Q: P is sister of Q (P female).
2. Q – R: Q is father of R; R ÷ S: R is son of S, so S is R’s mother and Q’s wife.
3. S × T: S is daughter of T.
4. So Q is T’s daughter’s husband, and P is his sister: P is T’s daughter’s husband’s sister.

Trick: Write relations from T’s side backward: T → daughter S → her husband Q → his sister P.

Answer: (A) Daughter’s husband’s sister

Concept: Compare positions: each letter of the first cluster vs the matching letter of the second cluster.

1. NP – KM: N−3 = K, P−3 = M.
2. KM – HJ: K−3 = H, M−3 = J; HJ – EG: H−3 = E, J−3 = G.
3. MP – LK: M−1 = L, P−5 = K — different rule.

Trick: Three pairs show a uniform −3 shift; the one breaking it is odd.

Answer: (A) MP - LK

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

1. Highest = 930 → first digit 9.
2. Lowest = 335 → third digit 5.
3. $9+5=14$.

Trick: Compare first digits only: 9 is highest, 3 is lowest.

Answer: (D) 14

Concept: Find the shift in the first pair and repeat it in the second pair.

1. Option B: T−3 = Q, V−3 = S, R−3 = O, so TVR → QSO.
2. XZV with −3: X→U, Z→W, V→S = UWS.

Trick: Letters QSO are spaced +2, −4; the answer cluster must keep the same spacing (UWS: +2, −4).

Answer: (B) # = TVR, % = UWS

Concept: Find the position-wise change from the first cluster to the second.

1. HMP → KON: H+3, M+2, P−2.
2. USQ → XUO: U+3, S+2, Q−2.
3. DLV → GNT: D+3 = G, L+2 = N, V−2 = T ✓.

Trick: Test only the first letter (+3) to shortlist: KWZ (−4) and DWP (+6), BIO (+4) fail at once.

Answer: (B) DLV : GNT

Concept: Look at the differences between consecutive terms.

1. Differences: $428-405=23$, $405-372=33$ — increasing by 10.
2. Next difference 43: $372-43=329$.
3. Check: $329-53=276$, $276-63=213$ ✓.

Trick: Differences 23, 33, 43, 53, 63 — an arithmetic pattern of +10.

Answer: (A) 329
