A simple peasant bought a number of camels and is taking them to his farm. As he rides contentedly along he counts them - he counts 29. He was sure he had bought 30 camel, so in alarm he jumps off his camel and counts the camels again. To his delight there are 30. Half an hour later, he counts his camels and once more there are just 29. Confused, he climbs off his camel and counts again. Once more there are 30. Can you explain?
It could be delivered by mail, email, by hand, or even by pigeon.
It is sometimes short, sometimes lengthy, and with deep, profound, or simple feelings.
What is it?
In a recreational activity, you are given four different jars of 2 liters, 4 liters, 6 liters and 8 liters respectively with an unlimited water supply. Then you are asked to measure exactly 5 liters of water using them.
How will you do it?
It's impossible!
You cannot measure an odd number of liters when we only have jars that hold odd amounts.
The Weight of Soap
Riddle:
We have two soap of equal weights and a 3/4 pound weight.
However, after using 1/4 of soap we place all three objects on balance as On one side of balance we place one soap (unused) and on another side, we placed used soap (i.e 3/4th of soap) and 3/4 pound weight.
What is the soap weight?
3 pounds.
if 3/4 of a pound weigh the same as a 1 quarter of the soap, then a simple formula is soap weight = 4 X 3/4 = 3 Pounds.
My Wall Clock
Riddle:
I have a clock in my house, on the wall.
On a summer's day I forgot to wind it and it stopped. Then I went to visit a friend who had a watch that was always right on time. After I stayed for a bit, I went home, made a simple alteration and set the clock just right.
Now how did I do this when I had no watch on me to tell how long it took me to come back from my friend's place?
Before I left, I wound the wall clock. Upon my return, the amount of change that I could see in the clock is how long it took to go to my friends place and come back, adding to that the time I spent there, which I know because the clock at my friend's place is accurate.
Subtracting the time of the visit from the time I was absent from my house, and dividing by 2, I obtained the time it took me to return home. I added this time to what my friend watch showed when I left, and set the sum on my wall clock.
Google Riddles - The Surprise Box
Riddle:
You have 3 boxes. One of them contains a prize. You were allowed to pick just one of them.
You pick - and it's empty.
With 2 boxes left, you now have one box in your hand and another box in front of you. If given the chance to exchange your box with the box in front of you, would you do it? Why, and why not?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
In the beginning, with 3 boxes, things were simple. You had a chance of 1 in 3 to find the prize. NOW we know that one of the boxes is empty but you still made a guess of 1 in 3, now you have a new choice of 1 in 2. Your probability goes up and that is why you SHOULD CHANGE THE BOX.
Don't feel bad if you disagree, this riddle has been hotly debated.
Google Riddles - The Return Flight
Riddle:
Today is more windy than yesterday, will a return flight take the same time, less time, or the same amount of time to complete?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
Let's do a worked example. Lets say our plane has to travel 300 miles there and 300 miles back. It has a standard cruising speed of 600mph. In the case of no wind it will travel the 600 miles in 1 hour exactly. Simple enough. Let us say that the wind speed is 100mph so the plane will be wind assisted to 700mph and slowed to 500mph - Wind Assisted: 300 miles at 700mph takes 0.429 hours - Wind Slowed: 300 miles at 500mph takes 0.6 hours - Total Time: 1.029 hours
