67 consulting riddles with answers (2023)

Queries can include complete cases, as well as brainstorming, estimates, puzzles, etc. So what is a puzzle? The definition of puzzle is"a puzzle or problem that requires great ingenuity to solve."In other words, the riddle is a short riddle designed to challenge your ability to think logically and make connections that aren't immediately obvious. And your ability to solve a puzzle gives the interviewer an indication of how flexible your mind is and whether you can think logically. If you give up easily when faced with a difficult problem, it could also indicate that quality companies certainly don't want future consultants.

Puzzles as part of your consultation preparation

Therefore, as clarified above, the riddles should be part of the preparation for the case interview. It helps keep your mind sharp and develops the habit of solving problems calmly and confidently, but with a sense of urgency. And the most important part of solving a puzzle is how you approach a problem. If you fail only one correct answer because you have heard a particular riddle before, you will not get any points. Also, giving an incorrect or illogical answer, or arguing with the interviewer that your answer is correct, can hurt you.

For example, imagine the following riddle that the interviewer gives you: “It is dark in your room. You have a lot of white socks and black socks in your drawer. You want to get a matching pair, but the socks aren't organized. All socks are identical except for the color. What is the minimum number of socks you need to bring to get a matching pair?

Now imagine you say: “I would say two. The task is to find a minimum number of socks. A minimum number of socks can be as follows. The first sock you get is black, the second sock you get is black. Likewise, the minimum number of socks can be: the first sock you receive is white, the second sock you receive is white.

This is the actual response we received from a member of the FC community. This answer is wrong.

If you try to push it, you will miss. The question is: "What is the minimum number of socks you need to bring to wear a matching pair?" You have to read between the lines. In other words, “What is the minimum number of socks you must bring?GuaranteeCan you get a matching pair to wear? You can find the correct answer to this question in the Puzzles with Answers section below.

Types of advice puzzles

What kind of puzzles can I find during a case interview?

The riddle of how many or the riddle:

Another type of puzzle, known as the "how many" puzzle or puzzle, is particularly common in the world of consulting interviews and is a skill consultants will use throughout their careers. Many of the techniques we use to solve and teach estimation cases have been developed by FIRMSconsulting based on our many years of business consulting experience. Examples of these types of questions are virtually endless: "How many bullets will fit in a standard Subaru?" "How many boxes of tissues did the average American pharmacy sell in 2019?" "How many driver's licenses does Wisconsin issue in a typical summer?" ? "One of the most common questions in this category is"How many gas stations are there in the United States?" you have the idea

These teasers can blow your mind. After all, how are you supposed to determine the answers if you don't have hard data to work with? They may seem like non-beginners, but that's not the case. Estimate teasers are one of the most important types of all because they are the best for showing off.andyou solve problems. The answer is not as important as the approach you use, the assumptions you make, and how you test the final answer. There is much to teach here. The lack of definitive answers is exactly what makes them so valuable; There is no way to avoid them or find a suitable solution by sheer luck. In fact, the people who ask such questions almost certainly don't know the answers.For this reason, you will not find estimation advances in this post.

By their very nature, riddle puzzles require an exchange of ideas between the interviewer and the respondent, something that a written page cannot accurately convey. Any attempt to condense the solution to an estimate advance into a short paragraph would completely defeat the purpose.

Look at the estimated cases in the counseling offer (eg, the counseling offer, season 1, withFélix) to answer these questions. You can sign up for access to all programs on StrategyTraining.com by becoming an Insider (Insider status is granted when you become an Insiderannual premium membership). Your ability to answer these types of questions during counseling sessions is critical. This type of question can be asked separately or as part of a complete business case.

Although we won't explore these types of puzzles further in this post, try to practice them yourself regularly. Even outside of the world of consulting, they are among the most useful mental exercises you can do.

If you need more details on solving estimate cases, we would like to provide you with a full download of the estimate case guide we have prepared for you as a gift, based on the FIRMSconsulting book on preparing for advice. This download contains a step-by-step guide to solving conjecture cases, including a detailed example with an answer. Below is a link to download your copy. It's totally free. Enjoy!

The Math Riddle, Math Riddles, and Math Riddles:

Examples of math puzzles are probability questions. This is not suitable as a brain teaser as it tests your math skills against your critical thinking and problem solving skills.

Math puzzles can be intimidating, but they are usually relatively easy, even if they don't seem like it at first. As you dig deeper, you'll find some that require a wide range of equations, formulas, and calculations to arrive at their solution.

On the other hand, the simpler and less specialized ones tend to focus on probability.

Interestingly, math puzzles can be a bit hard to pin down, as they usually don't involve numbers, while other types of puzzles occasionally do. That can be a good thing, as it encourages you to approach the problem with an open mind, rather than assuming you have to stick to proven mathematical solving techniques.

Most people today associate math with subjects like computer science, but it's important to remember that it didn't start out that way. In essence, the mathematical system is designed to help us understand how the natural world works, not to overcomplicate it. When it comes to brain teasers, math is your friend!

Or riddles make riddles:

In this puzzle, the interviewer presents you with a concrete problem situation and asks you to find a solution.The brain teasers are the kind of brain teasers that require you to think outside the box. They usually use language that tries to trick you and often involves words and phrases that don't mean what they first seem. These tend to be the most difficult types of taunts, as they are the most aggressive in getting you out of your comfort zone. They can also be the most rewarding; There are few things more satisfying than finding a single, simple solution to a puzzle that initially seemed impossible.

An example that will appear below is the following: "If a plane crashes right on the border between the United States and Mexico, where are the survivors buried?" Another example is a question about a farmer, a fox, a carrot, and a rabbit below.

When solving a puzzle, the most important thing is that you can only identify it as a puzzle. Once you realize that a question is the most probableattemptTo deceive him you can be much more careful and thus avoid falling into his traps. Each word in a puzzle is carefully considered, so don't forget anything, not even the smallest bit of punctuation. Do your best to view the information presented to you in a vacuum. Assumptions and snap judgments are a puzzle master's worst enemy. Above all, he remembers that you can solve anything if you put your mind to it. Relax, take your time, and of course, have fun!

Riddle "Why is that?":

"Why" puzzles are used to test your ability to analyze the world around you. They can be some of the hardest teasers to master, as many people often struggle to know where to start. They usually take a widely accepted quirk of the world around them and challenge you to find a reason for this to work the way it does. An example that appears later in this book is the following: "Why is a tennis ball out of focus?" This is a commonly used "why" riddle that emphasizes something that most people have never questioned.

Working with these types of teasers is a great way to think more critically about our environment, especially those created or designed by other people. We accept most modern conveniences for what they are and never think to question what made them that way, but nothing works a certain way "just because". Everything we use that is man-made is designed on purpose, and the more we can practice recognizing that fact, the more effectively we can solve our own problems, even when we are clueless, say, about the history of tennis.

Interview Questions That Aren't Riddles

Some interview questions may be difficult, but they may not be a mystery. These questions are usually about you rather than an external problem that you need to solve. Examples include:

"Are you more of a hunter or a gatherer?"

"If you were a box of chocolates, what kind of chocolate would you be and why?"

"How honest are you?"

"How would you explain the Internet to a 3-year-old?"

These interview questions can be divided into two opposing areas: subjective and knowledge-based.

A subjective interview question usually does not have a correct answer, or at least an answer that depends on the person answering it. In a job interview, this might sound like your typical "What's your biggest weakness?" or "Do you see yourself more as a leader or a follower?" There are certainly right and wrong ways to answer a question like this, but most of the time you can be successful simply by being honest about your experience and skills. In other words, a subjective question will never try to trick you the way a puzzle usually does.

A knowledge-based job application question measures your competency in a specific area; often highly specialized. When an interview presents you with one of these, it's trying to gauge your familiarity with a topic that's likely to be central to the job you're applying for. You can think of these questions as the type you might find on a high school history test. As long as you have the facts straight, you should be able to easily answer knowledge-based questions without overthinking or problem solving.

Compared to these other types of questions, puzzles can be easier or harder depending on how you tend to solve problems. As a candidate, you will never again have to deal with a riddle, or study a bunch of facts beforehand. However, you can improve your overall puzzle-solving ability with practice. Think of the riddles as exercises for your mind. Your brain is a muscle like any other, and the more you use it, the stronger it gets. That's why this post is here: to give you an extra chance to practice and improve your puzzle solving. With that in mind, this is another element of riddles that sets them apart from many other types of interview questions: if you relax and take your time, they can be a lot of fun!

Advisory riddle with answers

Now let's look at some real mysteries. As you read each puzzle, try to solve it with calm, confidence, and a sense of urgency. Think about the problem and, as slowly as you can, think about how your brain needs to find the answer.

I remember when I was studying difficult subjects in college, when I tried to read fast I got lost. Instead, what I needed was to slow down and think carefully about all the connections the author made to explain a particular point. Taking the time to think through a problem in stages often produces much faster and better results than solving it quickly.

We see this consistently with members taking the Consulting Offering training and even members taking our Advanced Consulting Skills training. Members who rush through material, jumping from episode to episode, program to program, trying to find shortcuts and quickly reading material, do not perform as well as members who diligently work through programs in order. that we recommend, choosing several carefully and mastering concepts and approaches.

The same logic applies to solving puzzles. If you are in a hurry, you are likely to find the wrong answer.

For example, if we look again at a riddle we considered earlier, the one about socks. Some candidates may immediately panic: "Oh, it's probably statistics. I have to understand the probabilities. My God, I don't know how to figure this out!"

However, all you have to do is imagine that you are in a dark room, there are black and white socks in the drawer. You must get a matching pair. What are the possible scenarios? Well, you can get 2 socks, but there's no guarantee they'll match.

Let's say you have 3 socks, the next lowest number. What are the possible scenarios? Well, you can get 3 black socks, 3 white socks, 2 white socks and 1 black sock, or 2 black socks and 1 white sock. In all possible scenarios, you end up with a matching pair. You see, if you think about the problem calmly, if you let your brain process the information, the answer is simple and obvious. The key is to trust that you're smart and that you'll figure it out, and to let your brain work at a comfortable speed to figure it out.

And have fun with it. If you solve a case during case interview preparation or during an actual case interview, have fun. try to have fun Having strong problem-solving skills is powerful. You can do a lot of good in the world if you are good at solving problems. So enjoy the process and trust your ability to figure things out.

Practice consulting riddles

It's important to note that difficulties are subjective, especially when dealing with structured problems designed to make you think outside the box. If you get stuck on a puzzle, try solving a few different ones before coming back to it, and rest assured, you'll only get faster as you learn reliable troubleshooting methods.

If you want to check your solutions or if you just can't solve a particular puzzle no matter how closely you look at it, you can always scroll down to the bottom of the section that has solutions for each puzzle. Each numbered solution includes an "Answer", which is a simple statement that provides the correct answer to the teaser and, if necessary, an "Explanation" that goes further into examining the strategies or thought patterns involved in the solution that you might apply. to the teaser problem. special provocation It is strongly recommended that you read the "Explanation" parts of the Solution Key, even if you have reached the correct conclusion. Often these pieces reveal ways in which you can simplify your thinking, making future puzzles of a similar nature that much easier.

So get ready: it's time for some mental gymnastics.

Simple Tips Puzzle

The following 41 puzzles are grouped under the Easy label, but that doesn't mean they aren't challenging. In fact, some people think that these puzzles are the hardest of all.Becauseits simplicity. If you are used to relying on calculations and complex logic, you should drop all prejudices about how to deal with these problems.

The most important tip to keep in mind for this section isverBe very careful with each question. If it seems too easy, he's probably cheating on you, and the same is true if it seems too difficult. Be aware of writing tricks, ambiguities, and the convergence of the literal and the metaphorical. Look for an "Aha!" Moment that puts the original teaser in a whole new light.

Let's start with a simple riddle. Prepare? Define. Go!

(1) A farmer tries to cross a river. He takes a rabbit, carrots, and a fox with him. He has a very small raft, so he can only carry one item across the river at a time. How does it cross the river?

Answers to simple counseling riddles

1. Take the rabbit, sail back. He catches the fox and returns to the rabbit. release the rabbit and collect the carrots; sail back and take the rabbit. However, there is an alternative answer. Take the bunny, sail back to get the carrots, sail back with the bunny to get the fox, go back again to get the bunny. The carrots and fox from step 2 are interchangeable.
2. jason Jason, Suzan, Jeffrey and Jennifer are siblings.
3. December 31. The day before yesterday was December 30 when he turned 17, yesterday was December 31 when he turned 18, today is January 1 and he will turn 19 and next year he will turn 20.
4. Three generations of a family. One of the “parents” is both a child and a parent.
5. The answer is your father, assuming your mother and father are married.

11. Only 1 time.
12. piano or any keyboard.
13. your word
14. only one After that it will not be empty.
15. Short answer.EXPLANATION: Saying this riddle out loud makes it much more difficult since you don't have the visual aid of the word "shorter". However, when you write, the solution is right in front of you. Adding two letters to a word does not make it smaller; on the contrary, it isbecomes "shorter"—literally becomes the word "shorter". And if you subtract those two letters, you get your answer: "short."
16. Only until you reach the middle of the forest. After that, a dog will run out of the forest.
17. ANSWER: Your horse's name is Montag.EXPLANATION: There are several ways to read this question. Most people will assume by default that you mean a day of the week, in which case there is no possible solution. Two days after Monday is always Wednesday, regardless of the month, year, etc. In this context, how can we find our solution? Something like "time travel" seems to be the only option left.con"Monday" actually refers to the day of the week. But there's no real confirmation of that in the riddle itself. The information we have received says that a man will arrive in the city on Monday. That must mean that he is physically riding something called "Monday", most likely a horse.
18. ANSWER: The man is bald.EXPLANATION: This type of puzzle makes us question our assumptions about the world. Of course, everyone knows that some people are bald. However, since bald men are in the minority compared to those with hair, our standard image of a "man" is usually not bald. Working with this default image, this puzzle can be quite confusing, but if we allow ourselves to think outside the box, the answer becomes obvious.
19. 12 months. Each month has at least 28 days.
20. Seven.
21. A window.
22. A bell.
23. Steps.
24. A sponge.

28. 1 brick weighs 2 kg.
29. I'm Rebecca's daughter.
30. "Speakers in the back."
31. ANSWER: A secret.EXPLANATION: This is actually a very easy puzzle to solve as long as you follow each step to its logical conclusion. First, realize that you are looking for an "it": an object, entity, or concept. Next, consider the only fact about this "it" that has been made available to you: it is intrinsically indivisible. What is characterized by its uniqueness? A secret. By definition, when you tell someone a personal secret, it is no longer a secret.
32. There is no smoke as it is an electric train.
33. Only 1 time because the next time you subtract 10 from 90.
34. amanda
35. Fog.
36. The letter g.
37. A map.
38. the letter r
39. A coat of paint.
40. a letter V
41. Answer: meat.EXPLANATION: Riddles often try to trick you with superfluous information while hiding really important facts. Here the key to solving the enigma is in the first three words: "John the butcher". Part of a butcher's job is to weigh meat for sale to customers. The riddle distracts him with information about John's height, but that alone isn't enough to determine his weight; therefore "regret" should not function as a reflexive verb. John regularly calculates the weight of something else, and since he is a butcher, that "something" is meat.

Advisory puzzles of medium difficulty

And here it is more difficult.

(1) What do you notice about the following sequence of numbers?
– 8, 11, 4, 9, 1, 6, 3, 0

And here is another rather difficult one.

(2) You have a 3-gallon jug and a 5-gallon jug. You must fill the 5 gallon jug with exactly 4 gallons of water. What would you do?

Another relatively easy one if you keep an open mind.

(3) How can you throw a ball, stop it, and make it fly in the opposite direction while only touching the ball once?

Likewise, this one is relatively easy if you keep an open mind.

(4) Imagine that you have to put a coin in an empty bottle and then seal the bottle with a cork. How did you get the coin out without removing the cork or breaking the bottle?

This is one of my favorites.

(5) You have 3 boxes. One is with apples, one is with oranges, and one is with a combination of apples and oranges. All the boxes are mislabeled. In other words, the label identifies the wrong contents of the box. You can only open 1 box, and without looking at the box you can take 1 fruit and look at it. How can you label all the boxes correctly?

Here is another one of my favourites.

Answers to the test riddles of medium difficulty.

1. The digits are in alphabetical order. (Eight, eleven, four, nine, one, six, three, zero)
2. Fill the 3 gallon jug. Pour into the 5 gallon jug. Refill the 3 gallon jug and slowly pour into the 5 gallon jug until full. Since the 5 gallon jug already contained 3 gallons, it will only fit 2 more gallons. And now you have 1 gallon in the 3 gallon jar. Remove the water from the 5 gallon jug, pour 1 gallon from the 3 gallon jug. Refill the 3 gallon jug and pour into the 5 gallon jug. You now have exactly 4 gallons of water in the 5 gallon jug.O, there is an alternative way. Fill the 5 gallon jug and transfer to the 3 gallon jug. You now have 2 gallons left in the large jug. Empty the small pitcher and pour the 2 gallons from the large pitcher into the small pitcher. You now have room for 1 gallon in the small jug. Completely fill the large jug, then try to fill the 3 gallon jug with the remaining 1 gallon jug. You now have 4 gallons in the large jug.
3. Chuck it.
4. Push the cork in.
5. Here is a very long statement from one of the FC members:“Let's call 3 labels Os (all oranges), As (all apples), OA (a combination of orange and apple). Since all the boxes are mislabeled, the possible fruits for each box are: OA (all oranges, all apples), As (all oranges, combination of both), Os (all apples, all apples).combination of both). Then take 1 fruit from an enrolled AO. Scenario 1: If it is orange, the box contains all oranges, the correct label should be Os. So the marking as must have a combination of both fruits, correct designation OA. The last box, correctly label as. Scenario 2: if it is an apple, similar logic”.This is a correct answer, but it helps to make it clearer during a real interview.
6. A really correct answer from one of theFC members:„Let's call 3 switches 1, 2, 3. Turn switch 1 longer, say 2 minutes; Switch 2 for 20 s. Go to the other room. The hottest lamp is controlled by switch 1, the slightly warm lamp by switch 2, the remaining lamp by switch 3.There is an alternative and faster way to do this. Briefly turn the switch one at a time until the bulb has warmed up. Delete it. Then turn on switch 2. Go into the room. The hot bulb that is not on is switch 1, the on bulb is switch 2, and the other one is switch 3.
7. There is a hole in the empty pocket.
8. none. Both weigh 1 kilo.
9. He fell off the bottom step.
10. 888+88+8+8+8.
11. Metric tons.
12. the letter m
13. Breathing.
14. A towel.
15. Hairdresser.
16. Your color since you drive the bus.
17. The boxers were women.
18. ANSWER: They will not be buried. At least not in the short term.
    EXPLANATION: The issue of geographical limits is irrelevant since the survivors are not buried. Sacrifices are a different matter of course, but that doesn't matter for this particular question. Always pay attention to questions that, despite being worded correctly, don't make any sense on closer inspection!

4. Monte Everest.
5. This is a lateral thinking problem. The answer here has nothing to do with the meaning of the words, but with the words themselves, the answer is the letter e.
6. NOTHING NO.
7. ANSWER: The down on a tennis ball makes it move more slowly through the air.
   EXPLANATION: This is a very common riddle and one that leaves most people completely blank at first. Don't panic, it's the worst thing you can do in a situation like this. Your interviewer certainly doesn't expect you to have advanced knowledge of tennis ball construction techniques, so it's okay if you don't know where to start. He steps back and looks at your target. It is true that tennis balls are hairy, and this property distinguishes them from balls used in other sports. Having established this, your next task is to identify what unique tennis characteristics would require modification to your particular type of ball. If you think about it a bit, you'll come to the conclusion that this is the only sport where ball-in-air time is the most important factor. That means the fuzz has to be related to that particular aspect in some way. From this it can be concluded that it helps to slow down the ball, which makes the game really playable.
