On the Fourth of July, someone robbed the Johnsons. Police officers questioned three neighbors-Kyle, Rachel, and Sam. Kyle said that he was watching some movies with his family. Rachel said that she was having a barbecue outside to celebrate Independence Day. And Sam said that he was at the post office; all of his colleagues saw him. Who is lying?
Think about the date of the robbery and the activities that people usually do on that day...
Sam is lying. The Fourth of July is a public holiday; he couldn't be working at the post office on this day.
When summer break ended, Mila told her friends about her vacation in Africa. Mila said, "Oh, it was great! But on the last day of my trip, a massive volcanic eruption happened; it didn't spoil my vacation only because I flew home that day,". Mila's friends didn't believe her. Why?
Think about what happens when a massive volcanic eruption occurs...
All flights must get canceled when a volcanic eruption occurs, so Mila couldn't have flown home on the last day of her vacation; she's lying.
There are 11 candles in front of you, all of them with burning wicks. Your friend blows out six of these wicks. How many candles will remain?
Think about what happens to the candles when the wicks are blown out...
The six candles that had their wicks blown out will remain. After all, one, the other five candles will eventually burn down, and two, I asked you how many candles will remain, NOT, how many flames will remain.
Karma is the most popular girl at her school. At the school's ball, four guys claim to be Karma's boyfriend. Keeping in mind that only the boyfriend tells the truth, can you guess who the boyfriend is if these are the four statements from the guys? 1) Guy #4 is the boyfriend. 2) I am the boyfriend. 3) Guy #1 is the boyfriend. 4) I am the boyfriend.
Think about who would say what if they were the boyfriend, and who would say what if they were not...
Guy #2 is the boyfriend. Only the boyfriend tells the truth, so he will say, "I am the boyfriend,"; therefore, either the second guy or the fourth guy is Karma's boyfriend. If the fourth guy was the boyfriend, then both he and the first guy would be telling the truth, which is against the conditions. Therefore, Guy #2 is Karma's boyfriend.
Colin recently bought a new motorbike. One morning, he polished the bike for his evening bike ride, closed the garage, and went to work. When Colin came back, he found that the motorbike was gone. The man called the police, and the officers questioned three neighbors. Jessica said that she had stayed home all day because she was sick. Elizabeth said that when she was walking her dog, she saw that the motorbike was still in the garage. Pete said that he had come to Colin's house to ask for some garden tools, but when nobody opened the door for him, he simply left. Who stole the motorbike?
Think about who had a reason to lie about their whereabouts that day...
Elizabeth stole the motorbike. She couldn't possibly see that the bike was still in the garage because Colin closed the garage before leaving to go to work.
A rookie police officer was working his assigned beat, but to make his job a little more interesting, he decided to bring his radar gun along with him. He began testing the gun by pointing it at various moving objects to determine their speed. He noted people were moving between one and three miles per hour; however, when he pointed his radar gun away from the crowd of people there, the gun suddenly read 80 M.P.H. Again he pointed it in the same direction, and he got a speed reading of 85 M.P.H. He continued pointing the radar gun toward the same general area for the next 30 minutes and recorded speeds ranging between 60 and 95 miles per hour. Considering the fact there were numerous people milling about the area he was patrolling, why do you suppose he never once reported any of these high speeds to his department? For the safety of all of these people, shouldn't a speed trap be set up or speeding tickets issued? What exactly was going on here?
Think about where the police officer might be standing, and what might be nearby that could be moving at such high speeds...
The rookie police officer was assigned to patrol a minor league baseball game. Most of his radar readings came from his pointing the gun at the various pitches the opposing pitchers were throwing during the game.
In the realm of intellect and wit, where riddles intertwine, a labyrinthine puzzle tests the sharpest mind. Within this riddle's depths, a story of knights and kings and a treasure untold shall unfold. Imagine a mighty chessboard, with sixty-four squares so grand, where black and white alternate, a captivating land. Upon this board, two knights are placed, noble in their might. Their mission: to find the treasure hidden out of sight. But here's the twist, the tricky part, the puzzle's cunning scheme: the knights must journey together, a duo they must seem. One knight moves north, then two steps to the right, while the other takes a diagonal leap, a path both swift and light. They continue their pursuit, weaving through the chessboard's squares, till they've visited each and every one, proving their thorough care. Now comes the question, the riddle's hidden key: how many times did their paths cross, tell me if you see. Remember, their moves are synchronized, each step taken as a pair. Calculate their crossings, and unravel the secret with care.
Think about the symmetry of the chessboard and the synchronized movements of the two knights. Focus on how their paths will mirror each other as they traverse the board.
To find the number of times the paths of the two knights cross, we need to analyze their movements on the chessboard. Let's assign coordinates to the squares of the chessboard. We can label the columns as A, B, C, D, E, F, G, and H (from left to right), and the rows as 1, 2, 3, 4, 5, 6, 7, 8 (from bottom to top). Now, let's examine the movements of the knights. The first knight moves one square north and two squares to the right, which can be represented as (2, 1) on the coordinate plane. The second knight takes a diagonal leap, moving one square northeast, which can be represented as (1, 1). We'll start by assuming the initial position of both knights is (0, 0). Now, let's track their movements: The first knight moves to (2, 1). The second knight moves to (1, 1). The first knight moves to (3, 2). The second knight moves to (2, 3). The first knight moves to (4, 4). By analyzing their movements, we can see that the knights' paths intersected once at the coordinate (2, 3). Therefore, the answer is that the paths of the knights cross once.

There are 3 light bulbs in three separate rooms. in front of you, there is a panel with 3 separate switches. They only turn on or off. You may look inside each room only once. How can you tell which bulb belongs to which switch?
Here's a hint: Think about the initial state of the bulbs and how you can manipulate them to gather the most information possible in a single glance. Consider using a "process of elimination" approach, and think about what you can learn from a bulb being ON or OFF.
You turn on any two switches, leave them for a few minutes, and turn one switch off. You enter each room only once. you know that the lightbulb that is lit belongs to the switch that was left on, the bulb that is off, but hot, belongs to the switch you turned off, and the cold bulb belongs to the switch you never touched.

Which number would be bigger: the product of all of the numbers on your calculator, or the SUM of those numbers?
Think about the number 0...
The sum would be bigger because multiplying any number by zero always results in zero. Yes, you have to include zero; it is also a number on your calculator.

You have 14 brown socks, 14 blue socks and 14 black socks in your sock drawer. How many socks must you remove (without looking to be sure) to have a matched pair?

Four. You will have a pair of one color or another.
Lazy Larry agreed to work on a job for his brother-in-law for thirty hours at eight dollars an hour, on the condition that he would forfeit ten dollars per hour for every hour that he idled. At the end of the thirty hours Larry wasn't owed any money and didn't owe his brother-in-law any money either. How many hours did Larry work and how many hours did he idle?
Think about the "break-even" point: if Larry didn't work at all, how much would he owe his brother-in-law?
Lazy Larry worked 16-2/3 hours and idled 13-1/3 hours. 16-2/3 hours, at $8.00 an hour amounts to the same amount as 13-1/3 hours at $10.00 per hour.
