About this RRB NTPC Reasoning practice test

General Intelligence & Reasoning is tested in both RRB NTPC CBT 1 (30 marks) and CBT 2 (35 marks), spanning Analogy, Classification, Number/Letter Series, Coding-Decoding, Blood Relations, Direction and Distance, Calendar and Clock, Syllogism and Venn Diagrams, and Non-Verbal Reasoning. Railway reasoning questions sit at a moderate, consistent difficulty rather than the puzzle-heavy style of bank exams, which makes steady practice across all question types more valuable than deep specialisation in any one chapter.

Answer key & quick explanations

Short answers for the sample questions above. Use this to self-check before generating a fresh AI-built mock test.

1. 1. Doctor:Hospital :: Judge:?

   Court

   The relationship is between a professional and the place where that professional performs their duties. A doctor works and treats patients in a hospital, and in the same way a judge presides over cases and delivers verdicts in a court.

2. 2. 6:42 :: 8:?

   72

   The pattern is n multiplied by (n+1): 6 x 7 = 42, so the same rule applied to 8 gives 8 x 9 = 72. Recognizing the multiplier relationship rather than a fixed difference is key to this analogy.

3. 3. CAT:24 :: DOG:?

   26

   Assign each letter its alphabetical position (A=1 ... Z=26) and add them up: C(3)+A(1)+T(20) = 24. Applying the same rule to DOG gives D(4)+O(15)+G(7) = 26.

4. 4. Odd one out: 121,144,169,200

   200

   121, 144, and 169 are perfect squares of 11, 12, and 13 respectively, but 200 is not a perfect square of any whole number. Spotting the squaring pattern immediately isolates the number that breaks it.

5. 5. Odd one out: Mercury, Venus, Pluto, Mars

   Pluto

   Mercury, Venus, and Mars are classified as full-fledged planets of the solar system, while Pluto was reclassified as a dwarf planet in 2006. The classification criterion here is planetary status, not size or distance from the sun.

6. 6. Odd triad: (6,36,108)

   (6,36,108)

   Each of the other triads follows the pattern n, n-squared, n-cubed, such as 4, 16, 64 (4 cubed = 64). In the odd triad, 6 squared correctly gives 36, but 6 cubed is 216, not 108, breaking the pattern.

7. 7. Series 2,5,10,17,26,?

   37

   The differences between consecutive terms increase by 2 each time: 3, 5, 7, 9, 11. Adding the next difference of 11 to 26 gives 37.

8. 8. Series B,D,G,K,P,?

   V

   The gap between letters increases by one position each time: +2, +3, +4, +5, and next +6. Starting from B(2) and adding these gaps lands on P(16), then P+6 gives V(22).

9. 9. Series 5,11,23,47,95,?

   191

   Each term is generated by doubling the previous term and adding 1: 5x2+1=11, 11x2+1=23, and so on. Continuing the rule, 95x2+1 gives 191.

10. 10. Coding: SUN=TVO, MOON=?

    NPPO

    The code shifts every letter one place forward in the alphabet (S to T, U to V, N to O). Applying the same +1 shift to M, O, O, N gives N, P, P, O.

11. 11. Coding: COLD=XLOW, WARM=?

    DZIN

    Each letter is replaced with its mirror-position partner in the alphabet, where position x maps to (27-x), so A pairs with Z, B with Y, and so on. Applying this to W, A, R, M gives D, Z, I, N.

12. 12. Coding: ROSE=URVH, CHAIR=FKDLU, FLOOR=?

    IORRU

    Every letter is shifted exactly 3 places forward in the alphabet, which is confirmed by both given examples (R to U, O to R, and so on). Applying the same +3 shift to F, L, O, O, R gives I, O, R, R, U.

13. 13. Blood relation: mother's only daughter

    Mother

    The 'only daughter of my mother' can only be the woman herself, since she has no sisters. This means the man's mother is the woman speaking, making her his mother.

14. 14. Blood relation: A related to D

    Granddaughter

    Since A is B's sister, A shares the same mother C as B, making A the daughter of C. As D is C's father, D is A's grandfather, so A is D's granddaughter.

15. 15. Blood relation: son of the only son

    Brother

    Since the grandfather has only one son, that son must be the girl's own father (as she is his descendant). The boy, being the son of the girl's father, is therefore her brother.

16. 16. Direction: 5N,3R,5R

    3 km, East

    Plotting on a grid from the start point: 5 km north reaches (0,5), turning right (facing east) for 3 km reaches (3,5), and turning right again (facing south) for 5 km reaches (3,0). This final point is 3 km due east of the starting point.

17. 17. Direction: Ravi 8S,6L,8L

    6 km, East

    Starting at (0,0), 8 km south gives (0,-8); turning left while facing south means now facing east, so 6 km east gives (6,-8); turning left again means now facing north, so 8 km north gives (6,0). This point lies 6 km due east of the start.

18. 18. Direction: distance Q to R

    10 km

    Placing Q at the origin, P is 6 km east at (6,0), and R is 8 km north of P at (6,8). The straight-line distance QR forms a right triangle with legs 6 and 8, giving a hypotenuse of 10 km by the Pythagorean theorem.

19. 19. Calendar: Jan 1 2024 to Jan 1 2025

    Wednesday

    Because 2024 is a leap year, exactly 366 days separate the two dates, and 366 divided by 7 leaves a remainder of 2. Advancing Monday by 2 days gives Wednesday.

20. 20. Clock angle at 7:20

    100 degrees

    Using the formula |30H - 5.5M|, at 7:20 this becomes |30x7 - 5.5x20| = |210-110| = 100. This measures the smaller angle swept between the hour and minute hands.

21. 21. Clock coincidences in 24 hours

    22 times

    In every 12-hour period the hands coincide 11 times, not 12, because one overlap gets 'used up' catching up to the starting position. Over a full 24-hour day this doubles to 22 coincidences.

22. 22. Syllogism: pens-pencils-erasers

    Both I and II follow

    Since all pens are pencils and all pencils are erasers, every pen is necessarily an eraser, confirming conclusion I. Because at least some erasers are pens (the ones that were originally pens), conclusion II also follows.

23. 23. Syllogism: books-pens-tables

    Only conclusion II follows

    Since some books are pens, and no pen is a table, those particular books (the ones that are pens) definitely cannot be tables, which confirms conclusion II. However, nothing is said about the books that are not pens, so we cannot conclude that no book at all is a table.

24. 24. Venn: neither cricket nor badminton

    12

    Using the union formula, students playing at least one sport = 35 + 28 - 15 = 48. Subtracting this from the total class size of 60 gives 12 students who play neither sport.

25. 25. Mirror image of clock time 3:45

    8:15

    The mirror image of a clock time is found by subtracting the given time from 12:00 (written as 11:60 for easy subtraction). So 11:60 minus 3:45 gives 8:15.

26. 26. Mirror image of word STATION

    NOITATS

    A vertical mirror placed to the right of a word reverses the left-right order of its letters. Reading STATION from right to left gives N-O-I-T-A-T-S.

27. 27. Paper folding and punching

    2 holes, symmetric about the fold line

    Folding the square in half brings the two halves into exact overlap, so punching through both layers punches the same relative spot on each half. Unfolding reveals two holes that are mirror images of each other across the fold line, equidistant from it.

28. 28. Symbol substitution arithmetic

    14

    Replacing each symbol with its assigned meaning turns 6 + 2 - 4 x 3 / 1 into 6 / 2 x 4 + 3 - 1. Solving left to right using order of operations: 6/2=3, 3x4=12, 12+3=15, 15-1=14.

29. 29. Father-son age puzzle

    46 years

    Let the son's present age be s and the father's be f, giving f+s=60 and f-6=5(s-6). Solving these two equations together yields s=14 and f=46, which checks out since 6 years ago the father was 40 and the son was 8, and 40 is indeed 5 times 8.

30. 30. Number pattern: a-squared plus b

    69

    The hidden pattern is (first number squared) plus the second number: 5-squared+3=28, 7-squared+2=51, and 9-squared+4=85, all matching the given values. Applying the same rule to 8 and 5 gives 8-squared+5 = 64+5 = 69.
