Your friend has 100 red marbles, 100 blue marbles and 2 jars. He proposes a game. He fills the jars with the marbles, put the two jars behind his back and tell you to pick one of them at random. You’ll then close your eyes, he’ll hand you the jar you picked, and you’ll pick a random marble from that jar. You win if the marble you pick is blue, and you lose otherwise. To give you the best shot at winning, your friend gives you the two jars before the game starts and says you can move the marbles around however you’d like, as long as all 200 marbles are in one of the 2 jars (that is, you can’t throw any marbles away). How should you move the marbles around to give yourself the best chance of picking a blue marble?

A student has missed an excessive number of days at school and thus the principal called him to his office and requested for an explanation. The student said, “There just isn’t enough time for school. I need 8 hours of sleep a day, which adds up to about 122 days a year. Weekends off is 104 days a year. Summer vacation is about 60 days. If I spend about an hour on each meal, that’s 3 hours a day or 45 days a year. I need at least 2 hours of exercise and relaxation time each day to stay physically and mentally fit, adding another 30 days. Add all of that up and you get about 361 days. That only leaves 4 days for school.” The principal is confused, but can’t figure out why. What is wrong with the student’s argument?

The paragraph below is very unusual. How quickly can you find out what is so unusual about it? “Gatsby was walking back from a visit down in Branton Hill’s manufacturing district on a Saturday night. A busy day’s traffic had its noisy run; and with not many folks in sight, His Honor got along without having to stop to grasp a hand, or talk; for a mayor out of City Hall is a shining mark for any politician. And so, coming to Broadway, a booming bass drum and sounds of singing, told of a small Salvation Army unit carrying on amidst Broadway’s night shopping crowds. Gatsby, walking towards that group, saw a young girl, back toward him, just finishing a long, soulful oration … “ The above passage is taken from the book “Gatsby” written by Ernest Vincent Wright in the late 1930s.

The court takes decision to relax the sentence given to criminal if he can solve a puzzle. Criminal has to take decision to open one of the doors. Behind each door is either a lady or a tiger. They may be both tigers, both ladies or one of each. If the criminal opens a door to find a lady he will marry her and if he opens a door to find a tiger he will be eaten alive. Of course, the criminal would prefer to be married than eaten alive. Each of the doors has a statement written on it. The statement on door one says, “In this room there is a lady, and in the other room there is a tiger.” The statement on door two says,”In one of these rooms there is a lady, and in one of these rooms there is a tiger.” The criminal is informed that one of the statements is true and one is false. Which door should the criminal open?

There is a prison with 100 prisoners, each in separate cells with no form of contact. There is an area in the prison with a single light bulb in it. Each day, the warden picks one of the prisoners at random, even if they have been picked before, and takes them out to the lobby. The prisoner will have the choice to flip the switch if they want. The light bulb starts off. When a prisoner is taken into the area with the light bulb, he can also say “Every prisoner has been brought to the light bulb.” If this is true all prisoners will go free. However, if a prisoner chooses to say this and it’s wrong, all the prisoners will be executed. So a prisoner should only say this if he knows it is true for sure. Before the first day of this process begins, all the prisoners are allowed to get together to discuss a strategy to eventually save themselves. What strategy could they use to ensure they will go free?

A Japanese ship was en route in the open sea. The Japanese captain went for a shower removing his diamond ring and Rolex watch on the table. When he returned, his valuables were missing. The captain immediately called the five suspected crew members and asked each one where and what he was doing for the last 15 minutes. The Filipino cook in a heavy overcoat said, “I was in fridge room getting meat for cooking.” The Indian Engineer with a torch in hand said, “I was working on generator engine.” The Sri Lankan seaman said, “I was on the mast (top of the ship) correcting the flag which was upside down by mistake.” The British radio officer said, “I was messaging to company that we are reaching the next port in 72 hours. From now that is Wednesday morning at 10 AM. The British navigation officer said, “I am on night watch, so sleeping in my cabin.” The captain caught the liar. So who is the thief?

One murder happened in a village. A police officer instructed two police constables to go to the crime scene, investigate and prepare an preliminary incident report. It was already past midnight and the crime scene was far away from the police station. The two constables decided not to travel to the crime scene and came up with a fake incident report instead. Below is the report. When we reached the spot, the door was open and one man aged between 40-45 was found dead lying on the floor. The light and fan were switched on. There were some items found on a table: – One open bottle of poison, – One half filled drinking water bottle, – One fountain pen, – One newspaper was flipped open, pages 9 and 10 facing each other, – One table top calendar showing June 20, – One notebook.

A guard is stationed at the entrance of a bridge. He is tasked to shoot anyone who tries to cross to the other side of the bridge, and to turn away anyone who comes in from the opposite side of the bridge. You are on his side of the bridge and want to escape to the other side. Because the bridge is old and rickety, anyone who tries to cross it does so at a constant speed, and it always takes exactly 10 minutes to cross. The guard comes out of his post every 6 minutes and looks down the bridge for any people trying to leave, and at all other times he sits in his post and snoozes. You know you can sneak past him when he’s sleeping, but the problem is that you won’t be able to make it all the way to the other side of the bridge before he sees you (since he comes out every 6 minutes, but it takes 10 minutes to cross). One day a brilliant idea comes to you, and soon you’ve successfully crossed to the other side of the bridge without being shot. How did you do it?

This puzzle has been said to have been invented by Albert Einstein as a boy and some claim that only 2% of the population can solve it. There are 5 houses in 5 different colors. All the 5 owners are of different nationality. The 5 owners drink different beverages, smoke different brand of cigars, and own different pets. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage. There are five houses. The Brit lives in the red house. The Spaniard owns the dog. Coffee is drunk in the green house. The Ukrainian drinks tea. The green house is immediately to the right of the ivory house. The Old Gold smoker owns snails. Kools are smoked in the yellow house. Milk is drunk in the middle house. The Norwegian lives in the first house. The man who smokes Chesterfields lives in the house next to the man with the fox. Kools are smoked in the house next to the house where the horse is kept. The Lucky Strike smoker drinks orange juice. The Japanese smokes Parliaments. The Norwegian lives next to the blue house. Who owns the zebra?

The King calls in three wise men and tells them to all close their eyes. While their eyes are closed, he goes around and puts a hat on each of them. “I put a blue or white hat on each of you,” the King says. “I won’t tell you what color each hat is, but I promise you that at least one of you has a blue hat.” “Now open your eyes,” he continues. “You may not communicate with each other at all. Within one hour, one of you must call out the color of your own hat. If you aren’t able to do this, or if anyone calls out the wrong color, I will have you all exiled from the kingdom.” The wise men open their eyes and look at the other mens’ hats. They stand there for almost the whole hour in silence, thinking. Just as time is about to run out, all three men figure out the color of their own hats and yell the colors out at the same time. You can assume that all three men are perfect logicians, that they know that the others are perfect logicians, and that they all think at the same speed. What colors are the three men’s hats?
