Top 50 Most Logical and Tricky Interview Questions with Answers
Top 50 Most Logical and Tricky Interview Questions with Answers
Introduction
Cracking an interview often requires more than just technical knowledge—it takes the ability to think on your feet. Logical and tricky questions are commonly used by interviewers across industries to assess problem-solving ability, critical thinking, and presence of mind. Whether you’re a student, fresher, or seasoned professional, preparing for such questions can give you a significant edge. In this blog, we’ve compiled 50 of the most logical and tricky interview questions with detailed answers to help you navigate even the toughest interview scenarios.
Let’s get into the tricky questions and answers,
1. What comes once in a minute, twice in a moment, but never in a thousand years?
Answer: The letter “M”.
Explanation: This question is a play on words. The letter M appears once in the word minute, twice in moment, and not at all in the phrase “a thousand years”. It checks your attention to detail and your ability to think abstractly.
2. A man pushes his car to a hotel and tells the owner he’s bankrupt. Why?
Answer: He’s playing Monopoly.
Explanation: This is a lateral thinking question. It seems like a real-world scenario, but it’s actually referencing the board game Monopoly, where players can end up bankrupt when they land on hotels they can’t afford.
3. How can you drop a raw egg onto a concrete floor without cracking it?
Answer: Concrete floors are very hard to crack!
Explanation: This question tries to misdirect your focus to the egg, but the trick lies in the wording. The question asks about the floor, not the egg. It’s a classic test of comprehension and misdirection detection.
4. You have two ropes that each take an hour to burn, but they burn unevenly. How can you measure 45 minutes?
Answer:
-
Light the first rope at both ends and the second rope at one end at the same time.
-
The first rope will finish burning in 30 minutes (since both ends burn toward the middle).
-
At that moment, light the second end of the second rope.
-
It will now burn in 15 more minutes.
Explanation: This puzzle tests problem-solving under constraints. The uneven burn rate makes it tricky, but burning from both ends compensates for that.
5. Why are manhole covers round?
Answer: Because a round cover cannot fall through its circular opening.
Explanation: This is a popular question in tech interviews (famously used by Microsoft). A round shape ensures safety, is easier to transport, and doesn’t require aligning edges—testing both logical reasoning and practical knowledge.
6. If you had only one match and entered a dark room with an oil lamp, some kindling wood, and a newspaper, which would you light first?
Answer: The match.
Explanation: It may seem like a question about priorities, but it’s about sequence. You can’t light anything without first lighting the match, so it’s a test of basic logic and common sense.
7. How many times do the hands of a clock overlap in a day?
Answer: 22 times.
Explanation: The hands of a clock overlap every 65 minutes and 27 seconds, not every hour. In 12 hours, they overlap 11 times. So in 24 hours, they overlap 22 times. This question examines your ability to think beyond intuition and analyze mathematically.
8. A clerk in a butcher shop is 5’10” tall. What does he weigh?
Answer: Meat.
Explanation: This question seems to focus on the clerk’s height but misleads you. The key is in his profession — a butcher or clerk in a butcher shop weighs meat, not himself.
9. What can travel around the world while staying in the same corner?
Answer: A postage stamp.
Explanation: A stamp is stuck in the corner of an envelope, yet it travels globally. This question tests abstract thinking and lateral connections.
10. You’re running a race and you pass the person in second place. What place are you in now?
Answer: Second place.
Explanation: If you pass the second person, you take their position, which is second. Many mistakenly say “first” due to instinct. This tests logic under pressure and clarity of thought.
11. Can you name three consecutive days without using the words Monday, Tuesday, or Wednesday?
Answer: Yesterday, Today, Tomorrow.
Explanation: This is a creative thinking question. It steers you toward literal day names, but the correct answer lies in relative time expressions, which also describe three consecutive days.
12. What has a head, a tail, but no body?
Answer: A coin.
Explanation: This is a riddle that plays on double meanings. A coin has a ‘head’ side and a ‘tail’ side, but no actual body. It’s often used to test lateral thinking.
13. A cowboy rode into town on Friday. He stayed three days and left on Friday. How is that possible?
Answer: His horse’s name is Friday.
Explanation: This question tricks you with assumptions about days of the week. The twist lies in the unexpected name of the horse. It checks your openness to non-obvious solutions.
14. What gets wetter the more it dries?
Answer: A towel.
Explanation: While a towel is used to dry things, it absorbs water in the process, making itself wetter. This question assesses wordplay and abstract thinking.
15. Imagine you’re in a room that’s filling with water. There are no windows or doors. How do you get out?
Answer: Stop imagining.
Explanation: This is a trick question based on wordplay. You’re told to “imagine,” so the escape is simply to end the imagination. It’s testing your attention to the language used.
16. What comes down but never goes up?
Answer: Rain.
Explanation: Rain always falls down from the sky and never goes back up in the same form. This kind of question assesses your grasp of natural logic.
17. If you throw a red stone into the blue sea, what will it become?
Answer: Wet.
Explanation: The question builds up with color imagery to distract you. The literal and most logical result is that the stone becomes wet. It evaluates your ability to resist overthinking.
18. What is always in front of you but can’t be seen?
Answer: The future.
Explanation: This question uses metaphorical logic. The future is always ahead of us in time but cannot be physically seen. It measures abstract reasoning skills.
19. What is so fragile that saying its name breaks it?
Answer: Silence.
Explanation: This question uses conceptual irony. Speaking “breaks” silence both literally and figuratively. It tests your capacity for interpreting abstract ideas cleverly.
20. What has keys but can’t open locks?
Answer: A piano.
Explanation: It’s a classic pun. A piano has keys (musical keys), but they’re not the kind used to open locks. This checks your ability to think in analogies and puns.
21. A girl has as many brothers as sisters, but each brother has only half as many brothers as sisters. How many brothers and sisters are there?
Answer: Four sisters and three brothers.
Explanation:
-
The girl has 3 sisters (excluding herself) and 3 brothers.
-
Each brother has 4 sisters (including the girl) and 2 brothers (excluding himself).
-
The logic works both ways. It’s a classic logical puzzle about understanding relationships.
22. Two fathers and two sons go fishing. They catch three fish. How is it possible?
Answer: They are three people: grandfather, father, and son.
Explanation:
-
Grandfather = father of the father
-
Father = son of the grandfather and father of the son
-
Son = child of the father
-
So, two fathers and two sons = 3 people.
23. You see a boat filled with people, yet there isn’t a single person on board. How?
Answer: All the people are married.
Explanation: The phrase “not a single person” is a pun. It doesn’t mean the boat is empty—it means there are no single (unmarried) people on it.
24. How can a man go 8 days without sleep?
Answer: He sleeps at night.
Explanation: The question mentions days, not nights. The trick is in interpreting the question too literally. It tests your ability to spot linguistic misdirection.

25. What can you catch but not throw?
Answer: A cold.
Explanation: This one plays on double meanings. “Catch” is meant medically here, not in the physical sense. It tests your language flexibility.
26. Forward I am heavy, but backward I am not. What am I?
Answer: The word “ton”.
Explanation:
-
“Ton” is heavy.
-
Backward, it becomes “not”, which is the opposite of heavy.
-
This is a word-based puzzle to test how well you play with spelling and direction.
27. A truck driver is going the wrong way on a one-way street. A cop sees him but doesn’t stop him. Why?
Answer: He’s walking.
Explanation: The trick is in assuming he’s driving because he’s a truck driver, but he’s not necessarily driving at that moment. This tests assumption-breaking.
28. What gets bigger the more you take away from it?
Answer: A hole.
Explanation: As you remove material from a surface, the hole becomes larger. A classic test of reverse logic.
29. The more you take, the more you leave behind. What are they?
Answer: Footsteps.
Explanation: Every step you take leaves a mark (a footprint), yet you don’t carry it forward. It’s a poetic way of testing metaphorical reasoning.
30. What has one eye but can’t see?
Answer: A needle.
Explanation: A needle has an “eye” (the hole through which thread is passed) but no vision. A play on terminology, testing how you handle homonyms and metaphors.
31. If it takes five machines five minutes to make five gadgets, how long would it take 100 machines to make 100 gadgets?
Answer: Five minutes.
Explanation:
-
One machine makes one gadget in five minutes.
-
So, 100 machines working in parallel will make 100 gadgets in the same five minutes.
-
It tests your understanding of unit rates and parallel processing.
32. I speak without a mouth and hear without ears. I have no body, but I come alive with wind. What am I?
Answer: An echo.
Explanation: This is a classic riddle that evaluates your metaphorical thinking. An echo “repeats” sound and seems alive, though it has no physical form.
33. You’re in a race. You overtake the last person. What place are you in now?
Answer: You can’t overtake the last person.
Explanation: If someone is last, there’s no one behind them. You can’t overtake the last unless you’re already behind them, which contradicts the premise. This is a logic trap.
34. Which weighs more: a pound of feathers or a pound of bricks?
Answer: Neither, they both weigh the same—one pound.
Explanation: This tests if you’re swayed by the mental image of weight. The units are the same—this is a test of objectivity and clarity under assumptions.
35. What has many teeth but can’t bite?
Answer: A comb.
Explanation: This one plays on the figurative vs. literal meaning of “teeth.” A comb has teeth, but they don’t bite—checking lateral associations.
36. A plane crashes on the border of two countries. Where do they bury the survivors?
Answer: Nowhere. You don’t bury survivors.
Explanation: It’s a trick of wordplay. Survivors aren’t dead, so there’s nothing to bury. It tests listening and comprehension under misleading context.
37. A farmer had 15 sheep, and all but 8 ran away. How many are left?
Answer: 8 sheep.
Explanation: The phrase “all but 8” means 8 sheep remained. Many get tricked into overthinking the numbers. It evaluates attention to detail.
38. What has a neck but no head?
Answer: A bottle.
Explanation: This checks your ability to think beyond literal body parts. Bottles have necks (the narrow top), yet no head—it’s a test of metaphorical reasoning.
39. The more you have of me, the less you see. What am I?
Answer: Darkness.
Explanation: As darkness increases, visibility decreases. This question tests ability to correlate abstract quantities with real-world consequences.
40. What comes before thunder?
Answer: Lightning.
Explanation: Based on natural phenomena, light travels faster than sound, so we see lightning before hearing thunder. It tests basic scientific reasoning in a tricky form.
41. You see me once in June, twice in November, but not at all in May. What am I?
Answer: The letter “E”.
Explanation:
-
June has one “E”
-
November has two “E”s
-
May has none
This tests pattern recognition and language decoding.
42. What can fill a room but takes up no space?
Answer: Light.
Explanation: Light illuminates a room but doesn’t occupy physical volume. It evaluates your ability to think in non-physical dimensions.
43. A man builds a square house with all four sides facing south. A bear walks by the house. What color is the bear?
Answer: White.
Explanation: The only place on Earth where all four walls of a house can face south is the North Pole. The bear must be a polar bear, which is white. This blends geography with logic.
44. What invention lets you look through a wall?
Answer: A window.
Explanation: A window is a clever, simple answer. It checks if you’re overcomplicating a basic concept.
45. What begins with T, ends with T, and has T in it?
Answer: Teapot.
Explanation:
-
Begins with “T”
-
Ends with “T”
-
Contains tea (T) inside
This question uses phonetic and spelling clues.
46. Which month has 28 days?
Answer: All of them.
Explanation: Every month has at least 28 days. The trick is in assuming the question refers only to February. It tests assumption bias.
47. If two’s company and three’s a crowd, what are four and five?
Answer: Nine.
Explanation: A shift from figurative language to simple math. This question tests whether you can change your approach based on context.
48. What disappears as soon as you say its name?
Answer: Silence.
Explanation: Speaking disrupts silence, literally making it vanish. It’s a metaphorical puzzle with a poetic edge.
49. If you have one match and enter a dark room with a candle, a lamp, and a fireplace, what do you light first?
Answer: The match.
Explanation: A classic trick question that checks logical order of actions. You must light the match before anything else.
50. Which is heavier: 100 kg of steel or 100 kg of cotton?
Answer: Neither. They weigh the same.
Explanation: Both are 100 kg, so they weigh equally. The image of bulky cotton tricks your intuition. This tests your ability to think quantitatively, not visually.
