SSC Reasoning Practice Set with Answers (Top 100 Questions)

SSC Reasoning Practice Set with Answers: Quick Overview

This SSC reasoning practice set has 100 exam-level questions with answers and short explanations. It covers the topics that SSC CGL, CHSL, MTS, GD and CPO papers test again and again: analogy, odd one out, number and alphabet series, coding-decoding, blood relations, direction sense, ranking, syllogism, Venn diagrams, calendar and clock, mathematical operations and missing numbers. Try every question first without looking at the answer, aim for about 30 seconds per question, and then check the answer key and note each mistake.

Key Takeaways

• 100 questions in 15 topics, every one with the correct option and a short explanation.
• Free and text-based: nothing to download, and easy to read on a mobile screen.
• Useful for SSC CGL, CHSL, MTS, GD Constable, CPO and any other exam with a reasoning section.
• Target: finish the set in 50 minutes and score 75 or more to be on track.
• Figure-based questions (mirror image, paper folding, embedded figures) are not included and need separate practice from previous year papers.

SSC Reasoning at a Glance

Reasoning (called General Intelligence and Reasoning in most SSC exams) carries a fixed share of every tier 1 paper, so a strong reasoning score directly lifts your total.

Note: SSC can change the pattern in any notification, so always confirm the numbers in the latest official notice of the exam you are preparing for.

What Is Covered in This Practice Set?

How to Use This Practice Set

1. Keep a timer. Give yourself 50 minutes for all 100 questions, or 12 to 15 minutes for one section of 25 questions.
2. Do not look at the answers first. Write your answers on paper (for example 1-B, 2-A) so you can compare later.
3. Check with the answer key. Use the quick answer table to get your score, then read the explanation of every question you got wrong or guessed.
4. Make an error log. Note the topic and the reason for each mistake (concept, calculation or time) and revise it before your next mock test.
5. Repeat after 7 days. Attempt the same set again and try to improve both your score and your time.

Q33. Answer: (D) EGI — Every letter of the group moves one place ahead each time: DFH → EGI.

Q34. Answer: (B) Y — Positions are 10, 11, 13, 16, 20 (gaps +1, +2, +3, +4). Next gap is +5: 20 + 5 = 25 = Y.

Coding-Decoding

Q35. Answer: (D) CRRNG — Each letter is moved two places forward (M→O, A→C, N→P, G→I, O→Q). Applying the same rule: A→C, P→R, P→R, L→N, E→G = CRRNG.

Q36. Answer: (D) KVM — Opposite letters add up to 27 in position: P(16)↔K(11), E(5)↔V(22), N(14)↔M(13). So PEN = KVM.

Q37. Answer: (D) 41 — S = 19, S = 19, C = 3, so 19 + 19 + 3 = 41.

Q38. Answer: (A) QBUI — Every letter is moved one place forward: P→Q, A→B, T→U, H→I = QBUI.

Q39. Answer: (C) FYBN — Each letter moves one place forward: E→F, X→Y, A→B, M→N = FYBN.

Q40. Answer: (D) EDRIRL — The letters move forward by 2, 3, 4, 5, 6 and 7 places respectively (F+2=H, R+3=U, I+4=M, E+5=J, N+6=T, D+7=K). For CANDLE: C+2=E, A+3=D, N+4=R, D+5=I, L+6=R, E+7=L = EDRIRL.

Q41. Answer: (C) LTLAZH — Each letter is moved one place backward: M→L, U→T, M→L, B→A, A→Z, I→H = LTLAZH.

Q42. Answer: (D) UVWFGPV — Every letter moves two places forward, so S→U, T→V, U→W, D→F, E→G, N→P, T→V = UVWFGPV.

Q43. Answer: (A) pa — "blue" is the only word common to the first two statements, and "pa" is the only code common to them. ("sky" is common to statements 1 and 3, and "ta" is common to them.)

Q44. Answer: (D) pi — "we" = gu (common to statements 1 and 3), "apples" = ro (common to statements 1 and 2). In statement 1 the only code left is "pi", so "love" = pi.

Blood Relations

Q45. Answer: (C) Sister — Ravi's grandfather's only son is Ravi's father. The daughter of Ravi's father is Ravi's sister.

Q46. Answer: (A) Uncle — A, B and C are siblings. C is D's father, so A (a male sibling of C) is D's uncle.

Q47. Answer: (B) Mother — The only daughter of the woman's mother is the woman herself. So the man's mother is the woman.

Q48. Answer: (B) Uncle — The brother of one's father is a (paternal) uncle.

Q49. Answer: (C) Husband — Q and R are P's children, and S is the father of R, so S is P's husband.

Q50. Answer: (D) Aunt — The wife of one's maternal uncle (mother's brother) is one's aunt.

Q51. Answer: (A) P × Q − R — P × Q means P is the father of Q, and Q − R means Q is the brother of R. So P is also the father of R. (P − Q × R makes P the uncle; P + Q − R makes P the mother; P × Q + R makes P the grandfather.)

Q52. Answer: (A) Maternal grandfather — Q is P's mother (P is Q's son). R is Q's mother and S is R's husband, so S is Q's father, i.e. P's maternal grandfather.

Direction Sense

Q53. Answer: (D) 6 km East — After 10 km north, turning right means east (6 km), and turning right again means south (10 km). The north and south distances cancel out, leaving 6 km east of the start.

Q54. Answer: (A) 10 km North-East — She is 8 km east and 6 km north of the start. Distance = √(8² + 6²) = √100 = 10 km, in the north-east direction.

Q55. Answer: (C) West — North turned 90° clockwise is East. East turned 180° anticlockwise is West.

Q56. Answer: (C) 13 m — Distance = √(5² + 12²) = √169 = 13 m (he is to the south-west of the start).

Q57. Answer: (B) South — East → left = North → right = East → right = South.

Q58. Answer: (D) North — In the morning the sun is in the east, so shadows fall towards the west. Ram's right is west, so Ram faces south. Shyam, facing Ram, faces north.

Ranking and Order

Q59. Answer: (A) 29 — Position from right = total − position from left + 1 = 40 − 12 + 1 = 29.

Q60. Answer: (A) 29 — Total = rank from top + rank from bottom − 1 = 7 + 23 − 1 = 29.

Q61. Answer: (B) 7 — B's position from the front = 30 − 15 + 1 = 16. People between A (8th) and B (16th) = 16 − 8 − 1 = 7.

Q62. Answer: (B) E — The order from tallest to shortest is D > A > B > C > E. So E is the shortest.

Q63. Answer: (B) 16 — Sohan's position from the left = 35 − 8 + 1 = 28. People between = 28 − 11 − 1 = 16.

Q64. Answer: (A) 17 — Rank from the start = 25 − 9 + 1 = 17.

Syllogism (Statements and Conclusions)

Q65. Answer: (C) Both conclusions I and II follow — Pens ⊂ books ⊂ tables, so all pens are tables (I follows). Since all pens are tables, some tables are pens (II follows).

Q66. Answer: (B) Only conclusion I follows — The cats that are dogs are also birds, so some cats are birds (I follows). Nothing is said about the other cats, so II does not follow.

Q67. Answer: (D) Only conclusion II follows — Birds are trees and no bird is a man, so some trees (the birds) are not men (II follows). A man can still be a tree that is not a bird, so I does not follow.

Q68. Answer: (C) Only conclusion II follows — “Some trees are stones” can be reversed to “Some stones are trees” (II follows). The stone-trees need not be flowers, so I does not follow.

Q69. Answer: (A) Only conclusion I follows — The apples that are oranges cannot be bananas, so some apples are not bananas (I follows). The other apples may or may not be bananas, so II does not follow.

Q70. Answer: (C) Both conclusions I and II follow — Doctors are engineers and no engineer is a teacher, so no doctor is a teacher (I follows). Teachers exist and none of them is a doctor, so some teachers are not doctors (II follows).

Venn Diagram and Set Problems

Q71. Answer: (A) 15 — Students playing at least one game = 60 − 10 = 50. Both = 35 + 30 − 50 = 15.

Q72. Answer: (C) 30 — Both = 70 + 60 − 100 = 30.

Q73. Answer: (A) 30 — Readers of at least one = 120 + 90 − 40 = 170. Neither = 200 − 170 = 30.

Q74. Answer: (C) 20 — Only Maths = students who like Maths − students who like both = 28 − 8 = 20.

Calendar and Clock

Q75. Answer: (B) Friday — 15 August 1947 fell on a Friday (count odd days from a known reference date, or use a calendar formula).

Q76. Answer: (A) Tuesday — 20 − 5 = 15 days later. 15 ÷ 7 leaves 1 odd day, so Monday + 1 = Tuesday.

Q77. Answer: (B) 5 — 100 years have 24 leap years and 76 ordinary years. Odd days = 76 × 1 + 24 × 2 = 124. 124 ÷ 7 leaves 5 odd days.

Q78. Answer: (C) 130° — Hour hand = 3 × 30 + 40 × 0.5 = 110°. Minute hand = 40 × 6 = 240°. Angle = 240 − 110 = 130°.

Q79. Answer: (C) 10° — Hour hand = 4 × 30 + 20 × 0.5 = 130°. Minute hand = 20 × 6 = 120°. Angle = 130 − 120 = 10°.

Q80. Answer: (C) 8:45 — Actual time = 11:60 − 3:15 = 8:45.

Q81. Answer: (B) 2000 — A century year is a leap year only if it is divisible by 400. 2000 is divisible by 400; 1900, 2100 and 2200 are not.

Mathematical Operations

Q82. Answer: (B) 24 — Replace the signs: 24 + 6 ÷ 3 × 4 − 8. By BODMAS: 6 ÷ 3 = 2, then 2 × 4 = 8, so 24 + 8 − 8 = 24.

Q83. Answer: (D) 16 — Replace the signs: 12 + 8 − 6 ÷ 3 × 2. So 12 + 8 − (6 ÷ 3) × 2 = 20 − 4 = 16.

Q84. Answer: (A) 169 — The rule is a @ b = a² + b²: 3² + 4² = 25. So 5² + 12² = 25 + 144 = 169.

Q85. Answer: (D) 40 — The rule is a * b = a² − b²: 36 − 16 = 20 and 81 − 25 = 56. So 7 * 3 = 49 − 9 = 40.

Q86. Answer: (A) 26 — After interchanging, the expression becomes 6 × 4 + 2 = 24 + 2 = 26.

Q87. Answer: (D) ÷ and × — 12 ÷ 4 × 3 = 3 × 3 = 9. The other options give 16, 13 and 11.

Missing Number

Q88. Answer: (C) 289 — In each group the third number is the sum of squares of the first two: 3² + 4² = 25, 5² + 12² = 169, so 8² + 15² = 64 + 225 = 289.

Q89. Answer: (D) 15 — In each row the third number is the sum of the first two: 2 + 3 = 5, 4 + 6 = 10, so 7 + 8 = 15.

Q90. Answer: (B) 42 — The third number is the product of the first two: 3 × 4 = 12, 5 × 2 = 10, so 6 × 7 = 42.

Q91. Answer: (A) 125 — Each number is cubed: 2³ = 8, 3³ = 27, 4³ = 64, so 5³ = 125.

Q92. Answer: (A) 41 — The third number is the sum of squares of the first two: 4 + 9 = 13, 9 + 16 = 25, so 16 + 25 = 41.

Q93. Answer: (C) 72 — The number in brackets is the product of the numbers on either side: 6 × 7 = 42, 5 × 6 = 30, so 8 × 9 = 72.

Alphabet and Word Tests

Q94. Answer: (C) 6 — The letters between D and K are E, F, G, H, I and J, which makes 6.

Q95. Answer: (D) Q — The 12th letter is L. Five places to the right (12 + 5 = 17) is Q.

Q96. Answer: (D) 2431 — The alphabetical order is Ballad, Ballast, Balloon, Ballot, i.e. 2, 4, 3, 1.

Q97. Answer: (B) 9 — EXAMINATION has 11 letters. Excluding the first (E) and the last (N) leaves 9 letters in between.

Mixed Reasoning (Age, Cube, Days)

Q98. Answer: (B) 20 years — Let the ages be 5x and 2x. (5x + 10) ÷ (2x + 10) = 2, so 5x + 10 = 4x + 20 and x = 10. The son is 2 × 10 = 20 years old.

Q99. Answer: (A) 12 — Only the cubes on the edges (not the corners) have exactly two painted faces. A cube has 12 edges and each edge of length 3 has 1 such middle cube, so 12 × 1 = 12.

Q100. Answer: (B) Monday — Day before yesterday = Thursday, so yesterday = Friday and today = Saturday. Tomorrow = Sunday and the day after tomorrow = Monday.

How to Check Your Score

In SSC CGL and CHSL Tier 1 every correct answer gives 2 marks and every wrong answer costs 0.50 marks. For this practice set, count the number of correct answers and use the table below as a guide.

Topic-Wise Tricks to Solve SSC Reasoning Faster

Analogy and Classification

• First name the relationship (place, function, category, part and whole, number pattern), then apply the same relationship to the second pair.
• For odd one out, check the category first, then patterns such as prime numbers, squares, cubes or letter gaps.

Number and Alphabet Series

• Check the difference between terms first, then the ratio, then squares, cubes and primes. If nothing fits, look at alternate terms.
• Convert letters to positions (A = 1 to Z = 26). Remember EJOTY: E = 5, J = 10, O = 15, T = 20, Y = 25.

Coding-Decoding

• Compare each letter with its code and find the shift. Check whether it is fixed (+2), increasing (+1, +2, +3) or opposite.
• In opposite-letter coding a letter and its opposite add up to 27 (for example A = 1 and Z = 26).
• For word substitution, find the word and the code that repeat in two statements.

Blood Relations

• Draw a family tree and mark male with (+) and female with (−). Start from the person mentioned in the question.
• For coded relations (A + B, A − B), first write what each symbol means and then build the chain step by step.

Direction Sense and Ranking

• Draw the path on a rough sheet. A right turn is clockwise and a left turn is anticlockwise.
• Learn common right-angled triples for the final distance: 3-4-5, 5-12-13, 8-15-17 and 7-24-25.
• Total people = position from one end + position from the other end − 1.

Syllogism

SSC reasoning follows the standard convention that “All A are B” also gives “Some B are A”. Use these quick results (draw a Venn diagram if unsure):

• All A are B + All B are C ⇒ All A are C.
• Some A are B + All B are C ⇒ Some A are C.
• All A are B + Some B are C ⇒ no definite conclusion about A and C.
• Some A are B + No B is C ⇒ Some A are not C.
• All A are B + No B is C ⇒ No A is C.

Clock and Calendar

• The minute hand moves 6° per minute and the hour hand moves 0.5° per minute. The angle between them is |30H − 5.5M|.
• Odd days: 100 years = 5, 200 years = 3, 300 years = 1 and 400 years = 0. A century year is a leap year only if it is divisible by 400.

Common Mistakes to Avoid in SSC Reasoning

• Guessing without elimination: with 0.50 negative marking, wild guesses cost more than they gain.
• Not converting letters to numbers: most coding and series errors come from doing it in the head.
• Skipping the diagram: direction, ranking, blood relation and syllogism questions are much safer when you draw them.
• Spending too long on one question: if a question needs more than a minute, move on and return later.
• Not reviewing mistakes: solving more sets without checking errors gives very little improvement.

Frequently Asked Questions (FAQs)

How many reasoning questions come in SSC CGL Tier 1?

In the current SSC CGL Tier 1 pattern, the General Intelligence and Reasoning section has 25 questions of 2 marks each, i.e. 50 marks out of 200. Always confirm the pattern in the latest official notification.

Is SSC reasoning easy or difficult?

SSC reasoning is usually moderate. Most questions can be solved in 20 to 40 seconds if you know the pattern, which makes it one of the most scoring sections for aspirants who practice topic-wise every day.

How many reasoning questions should I practice daily for SSC?

Practice 40 to 60 questions a day, spread across two or three topics, and attempt one full timed set (like this 100-question practice set) every week. Keep an error log and revise it before every mock test.

What is a good score in SSC reasoning?

Getting 20 or more questions right out of 25 with very few wrong answers (a net score of about 40 out of 50 marks) is considered a strong score. Cut-offs change every year and differ by exam and category, so use previous year cut-offs only as a guide.

Which reasoning topics are most important for SSC exams?

Analogy, classification (odd one out), number and alphabet series, coding-decoding, blood relations, direction sense, ranking, syllogism, Venn diagrams, mathematical operations and missing numbers are asked again and again. Non-verbal topics such as mirror image, paper folding and embedded figures also appear and need figure-based practice.

Does this practice set include figure-based (non-verbal) questions?

No. This set is fully text-based so that every question is clear on a mobile screen. For figure-based questions such as mirror image, water image, paper cutting and embedded figures, practice from SSC previous year papers.

How much time should I spend on one reasoning question in the SSC exam?

Aim for an average of 30 to 40 seconds per question, so the 25-question reasoning section is finished in about 12 to 15 minutes. Skip a question that is taking more than a minute and come back to it later.

Is there negative marking in SSC reasoning?

Yes. In SSC CGL and CHSL Tier 1, 0.50 marks are deducted for every wrong answer. Other exams such as SSC GD and CPO use different negative marking, so read the latest notification before the exam.

Will the same questions come in the SSC exam?

No, exact questions are not repeated in a predictable way. The practice questions follow the same concepts, patterns and difficulty level as SSC papers, so solving them builds the speed and accuracy needed for the exam.

What is the fastest trick for coding-decoding questions?

Write the alphabet positions (A = 1 to Z = 26), compare each letter of the word with its code to find the shift, and check whether the shift is fixed, increasing or reversed. For opposite-letter coding, remember that a letter and its opposite add up to 27.

How do I solve blood relation questions quickly?

Draw a small family tree, mark male with a plus and female with a minus, start from the person the question is about and move one generation at a time. For coded relations, convert each symbol into its meaning before drawing.

What is the difference between analogy and classification questions?

In analogy you find the relationship between the first pair and apply it to the second pair. In classification (odd one out) you find the one item that does not share the common property of the others.

Is this practice set enough to prepare SSC reasoning?

It is a strong starting set and a good weekly revision test, but it should be combined with SSC previous year papers, topic-wise practice and full-length mock tests for complete preparation.

Where can I get SSC previous year reasoning questions?

You can practice exam-wise previous year question papers for SSC CGL, CHSL, MTS, GD, CPO and JE on the PYQ section of SSC Education and solve them in the same time limit as the real exam.

Should I attempt reasoning first in the SSC exam?

Many candidates attempt reasoning first because it is quick and accuracy is high, which builds confidence for the harder sections. Choose the order that works best for you in mock tests, and stick to it in the real exam.

Can I save this reasoning practice set as a PDF?

Yes. Open this page in your browser, press Ctrl + P (or use the Print option on mobile), and choose Save as PDF. This gives you an offline copy of the questions and answers for practice.

Conclusion

Reasoning is the section where regular practice pays back fastest. Solve this 100-question set under a timer, go through every explanation, keep an error log and attempt the set again after a week. Add previous year papers and full mock tests, and your accuracy and speed will keep improving. Bookmark this page and share it with your study group so everyone can practice together.
