Here are 10 questions that might not test your intelligence so much as your ability to "think out of the box" (the answers are given below):
1. A man lives on the 28th floor of a high-rise building. Every day he gets the lift down to the ground floor to leave the building to go to work. Upon returning from work he always gets down at the 26th floor and has to climb the other two floors - unless it's raining! Why?
2. A man and his son are in a car accident. The father dies on the spot, but the boy is rushed to the hospital. When he arrives the surgeon says, "I can't operate on this boy, he is my son!" How can this be?
3. A woman had two sons who were born on the same hour of the same day of the same year. But they were not twins. How could this be so?
4. A murderer is condemned to death. He has to choose between three rooms. The first is full of raging fires, the second of assassins with loaded guns, and the third of lions that haven't eaten in 3 years. Which room is the safest for him to go to?
5. Can you name three consecutive days without using the words Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, or Sunday? (or day names in any other language)
6. A London cab driver picked up a lady who was a notorious chatterbox. He did not want to engage in conversation, so he pretended to be deaf and dumb. He pointed to his mouth and ears to indicate that he could neither speak nor hear. After she alighted, he pointed to the meter so that she could see how much she owed. She paid him and walked off. Then she realized that he could not have been a deaf mute. How did she know?
7. There are six eggs in the basket. Six people each take one of the eggs. How can it be that one egg is left in the basket?
8. Anthony and Cleopatra are lying dead on the floor of a room. Nearby is a broken bowl. There is no mark on either of their bodies and they were not poisoned. How did they die?
9. The boss of a storage warehouse had just arrived at work when one of his employees burst into his office. The man said that while asleep in the building the previous night he had dreamt that one of the stored boxes contained a bomb which would explode at two p.m. The boss was sceptical, but agreed to investigate. After a search, a bomb was truly found in the area foreseen in the man's dream. The police were called to defuse the bomb and thus a tragedy was averted. Yet afterwards, the boss after thanking the employee profusely, fired him. The sacked man had not planted the bomb, and his prophetic dream had saved the warehouse from a tragedy. Yet the manager was right to fire him. How could that be so?
10. A poor servant in a village was told by his master that he could wish for anything he wanted. It could be any wish at all but just one. The servant asked his mother what she wanted and she said she wanted a TV set. Next, the servant asked his wife who said she wanted a microwave. Finally, the servant went to his father who wanted a bicycle. The next day he went to his master and made one wish through which his mother, father and wife each got what they wanted. What was his wish?
1. The man is very short and can only press the button for the 26th floor. However, if it is raining then he will have his umbrella with him to press the higher button.
2. The surgeon was his mother (this is the type of questions you should watch out for in an interview, especially if the interviewer is a woman!)
3. They were two of a set of triplets (the third being a girl). Of course they can also be two of quadruplets, etc.).
4. The third. Lions that haven't eaten in three years would certainly have been dead.
5. Yesterday, Today, and Tomorrow!
6. He couldn't be deaf as he must have heard her instructions when she entered his taxi or he wouldn't have known where to take her.
7. The last person took the basket with the last egg still inside.
8. Anthony and Cleopatra were actually the names of two goldfish. The bowl was knocked over by a cat and they were left without water.
9. Because he was the night watchman (or some other night shift worker) and had been sleeping on his job.
10. Since it could be any wish at all, he asked for three wishes, thus satisfying everybody! Of course he could also simply ask for a sum large enough to allow him to buy all the three items.
Tytamayo from Texas has sent me this riddle, saying it is driving her absolutely crazy: There are 7 girls in a bus. Each girl has 7 backpacks. In each backpack, there are 7 big cats. For every big cat there are 7 little cats. Question: How many legs are there in the bus?
Assuming that this is a straightforward mathematical problem and that there is no one else in the bus, see if you can account for 10,990 legs?
Suleiman Garba Sulei of Bayero University, Kano, Nigeria, sent me the following brainteaser: In northern Nigeria there was a man who had 68 big camels and 3 sons Babangida the 1st born, Tanko, the 2nd born and Jatau, the last born. As he was about to die, he uttered his last words as follows: "If I die, Babangida, I don't like any lawyer to divide those camels as irrationally as the way he may like. So tell him this is how I want the camels to be divided among the three of you: You take half of the camels, Tanko takes one-third (1/3) and Jatau takes one-ninth (1/9) of the camels. That's how I like it, Babangida, no other way; don't let any of the camels be slaughtered and its meat be divided because it's against the rule of our forefathers to slaughter any of the camels."
If you were the lawyer, how can you divide the camels as their father wanted it?
How sharp are your eyes? There is no catch in this but you need to have very sharp eyes. See if you can find them all in under one minute (without using the cursor to help).

Is this dancer spinning to the right (clockwise) or to the left (anticlockwise)?
Whatever your answer is, you might be able to find someone who insists that she is spinning the other way. Well, we can never be too sure in life, can we? There is an explanation to this (it has to do with whether we are right-brained or left-brained). Just as we have a dominant hand, there is also a dominant side to our brain, says Margaret Rouse, director of whatis.com. According to whether we are right-brained or left-brained we process information in different ways. However she adds that no one is totally left-brained or totally right-brained. There are many others too who believe in the "right brain vs left brain" phenomenon. Actually it was an American Roger Sperry, a neuropsychologist, who initiated the study of the relationship between the brain’s right and left hemispheres. His split-brain research made him co-winner of the 1981 Nobel Prize in Medicine. His research showed that the two different sides of the brain control two different “modes” of thinking. Thus the left brain is logical, objective and analytical while the right brain is intuitive, subjective and focuses on creativity.
Hello,
I have a brainteaser that's been teasing my brain for some time now. I am hopeful that you will have an answer.
3 men go into a motel. The desk clerk said the room was $30, so each man
paid $10 and went to the room. A while later, the desk clerk realized the
room was only $25, so he sent the bellboy to the 3 guys' room with $5. On
the way, the bellboy couldn't figure out how to split $5 evenly between 3
men so he gave each man $1 and kept the other $2 for himself. This meant
that the 3 men each paid $9 for the room, which made a total of $27. Add to
that the $2 the bellboy kept and the total is $29. Where is the other
dollar?
- From Richard A. Feimer (message received by email)
Mr. Feimer has agreed to share this brain-teaser with others. Try to look at the problem from different angles.
Here is another brainteaser from Suleiman Garba Sulei of Bayero University, Kano, Nigeria: Four persons must cross a large lake to get back to their respective village. The 1st person sees the lake, touches its shallow water and crosses it safely. The 2nd person sees the lake, never touches its water but crosses it more safer than the 1st person and the last two persons don't even see the lake, never touch its water but they crossed it nevertheless.
Who are those four persons?
Names are not what they claim to be! (Thanks to Shirley Han for sharing).
1) How long did the Hundred Years War last?
2) Which country makes Panama hats?
3) From which animal do we get catgut?
4) In which month do Russians celebrate the October Revolution?
5) What is a camel's hair brush made of?
6) The Canary Islands in the Pacific is named after what animal?
7) What was King George VI's first name?
8) What color is a purple finch?
9) Where are Chinese gooseberries from?
10) What is the color of the black box in a commercial airplane?
A riddle for you (answer below*): When is a door not a door?
NOTE: Some of these need some thinking (mostly lateral thinking), others need no thinking at all, and as for the rest, you will never be able to find the answers if you think too hard!
1. There is no catch to this question but can you find the answer without using your calculator but through logical reasoning alone? Of the 800 women in an African village, 3% wear just one earring. Half of the remaining 97% wear two earrings while the other half don't wear any earring at all. What is the total number of earrings worn by the women in the village?
2. There are only two barbers in a small village and they have their shops opposite each other. A logician passing by saw that the first barber's shop was untidy, the barber himself was unkempt and had a lousy haircut. The barbershop opposite was clean and the barber was tidy and well-shaven yet he preferred to have his hair cut by the first barber. Why was this?
3. At a restaurant a customer found a fly in his cup of coffee just as he was about to drink it and asked the waiter to have it changed. When the waiter came back he took a sip and told the waiter: "This was the same cup that I had earlier." How did he know?
4. We were born of the same mother, on the same day, at the same hour and in the same year. Yet we are not twins. How do you explain this?
5.Two fathers and two sons were seated round a table. There were four apples on the table. Each of them took one apple and ate it entirely yet there was still one apple left on the table. How was this possible?
6. Before Mount Everest was discovered which was the highest mountain in the world?
7. Here everything is not always in order. For example, Friday comes before Thursday, the cart comes before the horse, the driver comes before the employer. Where are we?
8. In a drawer are 20 red socks and 20 black socks in complete disorder. If a man gropes in the dark and opens the drawer what is the smallest number of socks he must take out to be sure that he has one pair of the same colour?
9. When I am alive I stay put where I am. It is only when I am dead that I move about here and there. Who am I?
10. How can you be behind a person when that person is also behind you?
11. I am never the first to speak but I am always the last to be heard. Who am I?
12. This one has been withdrawn. (Someone wrote to say he was hurt by this brainteaser which plays around with the black colour. I personally don't see any insinuations to a certain race of people but we have to be sensitive to the feelings of others.)
(September 26, 2005) I decided to put back the above brain-teaser after receiving this email from 10GG (full name and email address withheld as requested):
You cannot allow a small number of people, one it looks like in this case,"Someone" to dictate what is or is not acceptable on your site, you are always going to upset a few people whatever you say but what gives them the right to censor what you believe to be decent and harmless and deprive the rest of us from seeing it.
Sensitivity to the feelings of others is fine but how do you decide when someone is being oversensitive to the point of being irrational.
If they don't like what you put on your site, no one is forcing them to use it.
Interesting site, please keep up the good work.
His argument makes sense to me so I am putting back the original brain-teaser which is as follows:
A black man, dressed completely in black, was crossing a highway leisurely when a black sports car came towards him at a terrific speed round a corner. Yet the driver managed to see him and was able to avoid him. How was this possible?
13. Jack was piloting a plane behind a car but was never able to overtake it. Why?
Given up trying? Need to know the answers? Go here. Answer to the riddle: When is a door not a door? *When it is ajar! Or perhaps the above riddles were all too easy for you? Then go here for Brainteasers 2.
